Question 1

When is the sunniest time of year in Nice?

Accepted Answer

The sunniest time of year in Nice is the summer, with July 2025 standing out as the brightest month of all. Across the full 2025 calendar year, Nice recorded an exceptional 3,103 hours of sunshine, averaging roughly 8.5 hours of sun per day.

Summer (June to August) was by far the sunniest stretch, delivering 1,133 hours of sunshine in 2025 — an average of about 378 hours per month. July led the way with 398 hours, equivalent to nearly 12.8 hours of sun each day. August followed closely with 385 hours, and June with 349 hours.

This brightness came with heat and dry skies. July 2025 saw average temperatures of 24.9°C (76.8°F) and peaked at 36.1°C (97.0°F), while the three summer months together collected just 73mm (2.9 in) of rain. By contrast, February was the least sunny month, with only 140 hours of sunshine.

For visitors planning around the weather, the late-spring-to-summer window offers Nice's most reliable sunshine. May 2025 already provided 296 hours of sun with milder temperatures, making it a comfortable alternative for those who prefer to avoid the peak summer heat. Whether you are heading to the Promenade des Anglais or exploring the surrounding hills, the months from June through August give Nice its signature Mediterranean glow — long, dry, and consistently bright.

Question 2

Which season is the wettest in Nice?

Accepted Answer

Spring is the wettest season in Nice, with the city recording 400.2 mm (15.8 in) of rainfall during spring 2025 (March to May) — far more than any other season that year.

Looking at 2025 by meteorological season, the rainfall pattern in Nice was clear:

- **Spring (March–May):** 400.2 mm (15.8 in)
- **Autumn (September–November):** 335.9 mm (13.2 in)
- **Winter (January–February 2025):** 188.4 mm (7.4 in)
- **Summer (June–August):** 73.4 mm (2.9 in)

March was the single rainiest month with 211.2 mm (8.3 in), while June was the driest at just 7.8 mm (0.3 in). Across the full year, Nice received 1,109.8 mm (43.7 in) of total precipitation in 2025.

These figures show that rain in Nice is strongly seasonal: spring and autumn deliver the bulk of the annual total, often through heavy bursts rather than steady drizzle, while summer stays reliably dry. If you want the warm, sunny Mediterranean weather Nice is known for with minimal rainfall, the June-to-August window is the safest bet. Travelers planning spring or autumn trips should pack a light rain jacket and expect occasional wet days, even though temperatures remain mild and pleasant throughout these shoulder seasons.
