Question 1

When is the sunniest time of year in Venice?

Accepted Answer

The sunniest time of year in Venice is the summer, with June 2025 being the single brightest month at 422.5 hours of sunshine — about 14.1 hours per day.

Across the meteorological summer (June to August) of 2025, Venice recorded roughly 1,131 hours of sunshine, averaging about 12.3 hours of daylight sun each day. August followed June closely with 361.0 hours, while July saw 347.8 hours. Over the full year, Venice tallied 2,947 hours of sunshine in 2025, equivalent to around 8.1 sunny hours per day on average.

If you prefer bright skies without the peak summer heat, late spring is an excellent alternative. May 2025 delivered 317.4 hours of sunshine alongside comfortable conditions, with an average temperature of 17.1°C (62.8°F) and daytime highs near 26.1°C (79.0°F). By contrast, June was considerably warmer, averaging 25.0°C (77.0°F) with highs reaching 33.5°C (92.3°F).

The darkest stretch in Venice is mid-winter: December 2025 managed just 113.9 hours of sunshine, or about 3.7 hours per day.

For sightseeing, photography, and exploring the canals, the long, luminous days from May through August give visitors the most reliable sunshine in Venice — with May offering the best balance of light and mild, pleasant weather.

Question 2

What were the temperature extremes in Venice in 2025?

Accepted Answer

Venice recorded its hottest day of 2025 on August 10, when temperatures peaked at 36.4°C (97.5°F), and its coldest reading on January 15, when the temperature dropped to -3.9°C (25.0°F). That gives Venice an annual temperature range of roughly 40°C (72°F) across the year.

Looking at the full 2025 calendar year, the city's weather was clearly defined by its seasons. June was the warmest month, averaging 25.0°C (77.0°F), while January was the coldest at just 5.2°C (41.4°F). The annual mean temperature settled at a mild 14.7°C (58.5°F), reflecting Venice's temperate Adriatic climate.

Hot spells were a regular summer feature. Venice saw 34 days reach or exceed 30°C (86°F) in 2025, including 4 days that climbed to 35°C (95°F) or higher. At the other end, winter brought 18 days with frost, where the minimum temperature fell to 0°C (32°F) or below.

These extremes have practical implications for visitors. Peak summer heat in July and August can make midday sightseeing in Venice uncomfortable, so early mornings and evenings are best for exploring. Winter, by contrast, is genuinely cold and damp, with frost and chilly fog common, making spring and autumn the most comfortable times to experience the city's weather.

Question 3

Which season is the wettest in Venice?

Accepted Answer

Summer is the wettest season in Venice, with the meteorological summer of 2025 (June 1 to August 31) delivering 343.9 mm (13.5 in) of rain — roughly a third of the city's annual total.

Across 2025, Venice received 1,048.9 mm (41.3 in) of precipitation. Summer led all seasons, followed by spring (March to May) with 249.0 mm (9.8 in) and autumn (September to November) with 243.2 mm (9.6 in). The portion of winter falling within 2025 (January and February) was by far the driest stretch at just 137.8 mm (5.4 in).

The single rainiest month was August 2025, when 145.4 mm (5.7 in) fell on Venice — more than any other month of the year. Much of this summer rainfall arrives as short, intense thunderstorms rather than the steady drizzle typical of cooler months.

For visitors, this means Venice's warm summer weather comes with a real chance of heavy downpours, so packing a compact umbrella and planning flexible indoor options is wise from June through August. If you prefer drier conditions, late winter and mid-autumn months in Venice tend to see less total rainfall, making them appealing windows for exploring the city's canals and squares with a lower risk of being caught in a storm.

Question 4

What is the weather like in Venice in August?

Accepted Answer

August is the height of summer in Venice, bringing hot, humid days, warm nights, and occasional heavy thunderstorms. In August 2025, the city averaged a mean temperature of 24.4°C (75.9°F), making it one of the warmest months of the year.

Daytime highs in Venice averaged 28.5°C (83.3°F), while nights stayed mild at around 20.6°C (69.1°F). The month peaked with a scorching 36.4°C (97.5°F) on August 10, and 10 days climbed to 30°C (86°F) or hotter. Humidity averaged 69%, which can make the heat feel more intense around the canals and crowded squares.

Despite the heat, August was also the wettest month of 2025 in Venice. Rainfall totalled 145.4mm (5.7in) across 11 rainy days, much of it falling in short, intense bursts. The single wettest day was August 20, which delivered 46.7mm (1.84in) of rain on its own.

The upside is plenty of sunshine: Venice recorded 361 hours of sun in August 2025, averaging roughly 11.6 hours per day.

For visitors, this means August in Venice is reliably warm and bright but demands a flexible plan. Pack light, breathable clothing and sun protection, but keep a compact umbrella handy for sudden afternoon downpours. Early mornings and evenings offer the most comfortable conditions for sightseeing, while the midday heat and humidity are best spent on a shaded terrace or a cooling boat ride across the lagoon.

Question 5

How windy is Venice, and which months are windiest?

Accepted Answer

Venice is a relatively calm, low-wind city, averaging just 10.8 km/h (6.7 mph) across 2025, with the windiest conditions arriving in spring and summer rather than winter.

Wind speeds in Venice stayed within a narrow band throughout 2025, ranging from 9.7 km/h (6.0 mph) to 12.2 km/h (7.6 mph) month to month. The windiest single month was April 2025 at 12.2 km/h (7.6 mph), closely followed by July at 12.1 km/h (7.5 mph). The calmest month was January 2025, averaging only 9.7 km/h (6.0 mph).

Looking at seasonal patterns, summer (June–August 2025) was the breeziest period at 11.9 km/h (7.4 mph), while winter (January–February 2025) was the most still at 9.85 km/h (6.1 mph). Spring and autumn fell in between, at 11.3 km/h (7.0 mph) and 10.2 km/h (6.3 mph) respectively.

For visitors, this means Venice offers gentle, manageable breezes year-round, ideal for gondola rides, walking tours, and waterfront dining. The slightly stronger spring and summer winds help take the edge off warmer afternoons, while the calm winter air keeps conditions stable for sightseeing. Overall, wind is rarely a disruptive factor when planning a trip to Venice.
