Florence sits in an Apennine river valley with a transitional Mediterranean climate — mild winters, hot dry summers, wetter springs and autumns. Temperatures swing from 2°C overnight in January to 35°C+ midday in July, the city radiates heat from its stone-built centre, and rainfall concentrates in November and April. This 2026 climate guide covers Florence’s weather month by month, what to expect from each season, the daily temperature curves you’ll actually feel as a tourist, and how the climate affects sightseeing, packing and travel decisions.
Turn the forecast into a suitcase with our Florence packing list, and keep our rainy day guide to Florence bookmarked for the days it does not cooperate.
Florence’s Climate: The Big Picture
Florence’s official Köppen classification is Cfa — humid subtropical, also referred to as transitional Mediterranean. Three local features make it different from the textbook Mediterranean of Rome or Naples:
- Inland valley geography. Florence sits 50km inland in a basin surrounded by the Apennine foothills. Air movement is limited, which exaggerates summer heat (no sea breezes) and autumn humidity (moisture pools).
- Hotter summers than coastal Tuscany. July and August averages run 4–6°C hotter than the Versilia coast 80km west; sea-level breezes don’t reach the city.
- Wetter than Mediterranean stereotype. Florence receives 800mm of rain annually, distributed across all four seasons, with peaks in November (114mm) and April (75mm). It is not the dry Mediterranean climate of southern Italy.

Florence has more than 800mm of total annual rainfall — wetter than London or Madrid, drier than Dublin. The two driest months are July and August; the wettest is November.
January in Florence
Florence’s coldest month. Daytime highs hover at 8–11°C, overnight lows 0–4°C. Frost on cars in the early morning is common; light snow falls roughly once per winter (typically just enough to cover roofs for a few hours before melting). Sunset is around 17:00 in the first week, 17:30 by month’s end. Daylight runs from 08:00 to 17:30.
Rain falls roughly 9 days of the month, but the city’s defining January weather is cold humidity — damp grey days when 5°C feels like 0°C. Layered wool clothing is essential. Most January days are walkable for sightseeing if you dress for it.
The single most affecting January phenomenon: the surrounding Apennines turn snow-capped, and sunny days produce dramatic mountain views from Piazzale Michelangelo and the Boboli upper terraces. The city itself rarely gets snow, but the mountain backdrop is more visible in January than any other month.
February in Florence
Slightly warmer than January, with the first hints of spring in the second half of the month. Highs 11–13°C, lows 2–5°C. Almonds and forsythia bloom in late February in the Boboli and Bardini gardens, but mimosa (the Italian symbolic flower of International Women’s Day on 8 March) hits its peak in late February in protected microclimates.
Rainy days remain at 8–9, but rainfall totals are slightly lower than January. The biggest February characteristic is variability — a single February week can include a 16°C sunny afternoon and a 1°C snowy morning. Pack for both.
March in Florence
Spring’s official start. Highs climb from 12°C in early March to 17°C by month’s end, with first 20°C+ afternoons appearing in the third week. Daffodils, almond blossom, and the first wisteria buds open in city gardens.
March is wet — 9 rainy days, with significant late-month rainfall as the polar jet stream meets warming Mediterranean air. The classic March Florence weather is “three days sunny, two days raining”; pack a packable rain jacket and an umbrella. Crowds remain low and museums walkable.
April in Florence
April is when Florence visibly becomes a spring city. Highs climb from 16°C to 22°C through the month. The Bardini Garden’s wisteria peaks in mid-to-late April; the Iris Garden opens in the last week. Easter falls between late March and late April depending on the year (5 April in 2026); the Scoppio del Carro Easter Sunday tradition is a major local event.
April is moderately rainy — 9 days, 75mm. The defining April pattern is April showers: heavy 30-minute downpours in the afternoon followed by golden evening light. Outdoor sightseeing remains comfortable; layers and an umbrella suffice.
May in Florence
May is widely considered Florence’s most beautiful month. Long sunny days (9 hours of sunshine), highs 22–26°C, low rainfall, peak garden colour. Rose Garden in full bloom; Iris Garden in peak bloom (third week of May); roses also climb every Oltrarno wall.
The first really hot afternoons (28°C+) start in the last week of May, but the city remains easily walkable. Crowds rise visibly through the month, and museum slot booking lead-times grow from 1 week (early May) to 3+ weeks (late May).
June in Florence
Summer’s first month. Highs 26–30°C, with the historical centre’s stone radiation making feel-temperatures 3–5°C hotter at midday. Long days — sunset around 21:00 — make outdoor evening dining the norm.
June is Florence’s driest month after July — 5 rainy days, 53mm total. Major events include the Calcio Storico Fiorentino (24 June, medieval football tournament) and the Festa di San Giovanni (24 June fireworks over the Arno). The city begins its Estate Fiorentina outdoor cinema, dance and music programming.
July in Florence
July is hot. Average highs 32°C, with regular spikes above 36°C and occasional heatwaves to 40°C. Overnight lows 18–20°C don’t fully cool the city — the historic centre remains warm at midnight. Sunshine 11 hours per day, only 3 rainy days. The defining July feature is the 4pm to 7pm afternoon heat trap: stone-radiation peaks, and outdoor sightseeing becomes uncomfortable until evening.
Practical adaptations: schedule outdoor activities for 09:00–11:30 and after 19:00. Use mid-afternoons for air-conditioned museums or hotel siesta. Hydrate aggressively (refillable bottle plus city’s nasoni drinking fountains). Wear breathable linen and cotton, wide-brim sun hat, SPF 50+ sunscreen.
August in Florence
Identical climate to July — 32°C highs, dry, 10 hours of sunshine. The differences are social rather than meteorological: Ferragosto (15 August national holiday) sees Florentines vacate the city for the coast or the mountains, and family-run shops, butchers, bakers and small trattorias close for 1–3 weeks around mid-August.
Tourist-facing businesses (major museums, big hotels, chain restaurants) remain open. The city’s daily rhythm thins, but the Estate Fiorentina outdoor programming continues. Heat strategies are identical to July.
September in Florence
The transition month. Highs cool from 28°C in the first week to 23°C by month’s end. The first heavy autumn rain typically arrives in mid-to-late September after the August dry stretch.
September is reliably warm but increasingly bearable for outdoor sightseeing. Italian schools return in mid-September, and tour groups begin shifting from peak family travellers toward older retirees and culture-focused trips. Hotel rates start dropping in the third week.
October in Florence
October is Florence’s most-recommended month. Highs 19–24°C, dry first half, occasional rain in the second half, exceptional Tuscan harvest light. Crowds drop noticeably from summer peaks, museum bookings need only 1–2 weeks of advance notice, and hotel rates settle into pre-Christmas low season.
The surrounding Tuscan countryside shifts to autumn colours through October — vineyards turn gold-orange, oak forests russet. Day trips to Chianti, San Gimignano and the Val d’Orcia are at their most photographically rewarding.
November in Florence
November is Florence’s wettest month — 114mm rainfall across 11 rainy days, often delivered in 24–48 hour stretches of steady rain. Highs 13–17°C, lows 5–8°C. Daylight shortens to 9.5 hours by month’s end (sunset before 17:00). Humidity peaks at 83%.
Despite the wet, November is excellent for budget travellers — hotel rates 30–45% off peak. The new olive oil (olio nuovo) arrives mid-November, the trifle festivals run through the month, and the city’s restaurants shift to hearty seasonal Tuscan cuisine. Pack waterproof boots, an umbrella and a warm jacket.
December in Florence
December is cool and damp. Highs 10–13°C, lows 2–5°C. 9 rainy days, 76mm of rain. Daylight is shortest in the year — sunrise 07:50, sunset 16:45. Christmas markets open on Piazza Santa Croce and Piazzale Donatello in late November and run through Epiphany (6 January).
December has two distinct phases: the first three weeks are off-season (low crowds, low rates), and the last 10 days plus first week of January are peak holiday (rates spike to summer levels). Snow is rare but possible — January is more likely.
“Feels Like” Temperature: Florence’s Stone Heat Trap
The official temperature reading at the airport doesn’t capture how Florence actually feels at street level. Three local features distort the experience:
- Stone radiation. The historic centre’s pietra forte slabs absorb heat through summer days and re-radiate it for hours after sunset. Midday felt-temperatures in July are typically 4–6°C above the airport reading.
- Narrow streets. Many medieval streets are 3–5m wide between 4-storey buildings, blocking breeze and trapping heat. Squares and the Lungarno embankments are several degrees cooler.
- Limited sea breeze. Florence’s inland-valley position means almost zero coastal moderating effect.
The flip side is winter — the same stone walls produce a damp chill that makes 5°C feel like 0°C. Layered wool, scarves and waterproof footwear are necessary in December and January even when the thermometer reads “mild.”
Florence Rain: Patterns and Adaptation
Florence’s rainfall pattern matters more than the totals. Three rainfall types occur:
- Spring/autumn afternoon thunderstorms — typically 30–60 minutes of heavy rain followed by dramatic golden-hour light. Common in April, May, September, October.
- Multi-day frontal rain — November’s signature pattern. 24–72 hours of steady rain followed by a clear two-day window.
- Light winter drizzle — December and January’s typical “rainy day” is a grey day with light continuous rain rather than dramatic downpour.
Practical adaptations: an umbrella (compact for handbag) is essential gear from October through April. A waterproof jacket is preferable in shoulder season; in winter, layered wool plus waterproof outer is the formula. Don’t reschedule whole sightseeing days for spring/autumn rain — typical morning rain clears by midday.
Extreme Weather Events
Florence experiences several types of extreme weather, each rare but occasionally affecting tourists.
- Heatwaves. July and August can deliver multi-day stretches of 38–42°C. Italian civil protection issues “red alert” warnings; museums extend opening hours, public hospitals see heat-related admissions surge. Take heatwave warnings seriously — schedule outdoor activities only before 11:00 and after 20:00, use air-conditioned spaces during the day, hydrate continuously.
- Flooding. The Arno River last seriously flooded Florence in November 1966 (5+ metre rise, devastating); subsequent flood-control engineering makes a repeat unlikely but not impossible. Light Arno rises during heavy autumn rain are normal and not dangerous.
- Snow. Light snow occurs 0–2 times per winter. Heavy snow (multi-cm accumulation) is a multi-decade event. The 2018 snow that closed the Cathedral for a day was the city’s biggest in 20+ years.
- Strong wind / hail. Spring and autumn can produce localised hailstorms with golf-ball-sized hail damaging cars and street vendors. Hide indoors when forecast.

Florence Weather FAQ
What is the hottest month in Florence?
July and August are tied — average highs 32°C, regular spikes above 35°C, occasional heatwaves to 40°C. The historic centre’s stone radiation makes felt temperatures 4–6°C hotter than the airport reading.
What is the coldest month in Florence?
January — average high 10°C, low 2°C, with overnight frost common and rare snow possible. Damp humidity makes the felt temperature several degrees colder than the thermometer suggests.
When does it rain most in Florence?
November (114mm, 11 rainy days) is the wettest month, followed by April (75mm, 9 days) and October (96mm, 9 days). July is the driest at 37mm.
Does it snow in Florence?
Light snow falls 0–2 times per winter, typically January. Heavy snow with multi-cm accumulation is a multi-decade event. Snow on the Cathedral and Ponte Vecchio is photographically dramatic but melts within 12–24 hours.
How humid is Florence?
Annual average relative humidity around 70%, peaking at 83% in November and dropping to 58% in July. Summer humidity is low (Florence is dryer than coastal Italy in summer); winter humidity is high and contributes to the “feels colder than the thermometer” sensation.
What month has the best weather in Florence?
May (24°C high, 9 hours sun, 8 rainy days) and October (21°C high, 6 hours sun, 9 rainy days) are the consensus best-weather months. Both deliver mild temperatures, manageable rainfall, and exceptional outdoor light.
Should I bring a rain jacket to Florence?
Yes — every month except July reliably sees 5+ rainy days. A packable waterproof jacket and a compact umbrella are essential year-round.
Do hotels in Florence have air conditioning?
Most 3-star+ hotels and major chains have reliable air conditioning. Older B&Bs, family-run guesthouses, and some Oltrarno apartments either lack AC entirely or have window units that struggle with 35°C+ summer heat. If visiting in July or August, verify AC quality before booking — “AC available” is not always the same as “AC reliably cools the room.”
Florence’s climate rewards travellers who plan around it. Mild spring and autumn shoulders deliver the best balance of weather, light and crowd levels; summer requires aggressive heat adaptation; winter offers solitude and Apennine views in exchange for damp cold. Pack for the season, watch for the predictable rain patterns, treat July and August as “morning and evening only” months, and you’ll find a Florence that fits whatever weather profile you prefer.
