| Annual rainfall | 650mm |
| Rain days per year | 80 |
| Odds on an average day | 22% |
| Wettest month | November — 95mm over 12 days |
| Driest month | July — 10mm over 1 days |
| Rain type | thunderstorms |
| Best dry window | July and August are virtually rainless with intense Mediterranean sunshine — the maquis shrubland is aromatic in the heat. |
| Worst rain window | November brings heavy storms — flash flooding in mountain valleys is possible and some GR20 sections become dangerous. |
November delivers 850% more rain than July (95mm vs 10mm). That gap is the difference between planning around showers and ignoring them.
No single month holds more than 15% of the annual total, so rain in Corsica is spread through the year — there is no season you can rely on being dry.
Corsica rain arrives in short, heavy bursts — shelter and timing matter more than gear.
Rain falls on about 12 days in November against 1 in July — the frequency swing matters more for planning than the millimetre totals.

Rain probability is the chance that at least 0.2mm falls at your location — not how long it rains. For Corsica we combine the hourly probability curve, expected volume in millimetres, and the city's own rainfall record into a single umbrella verdict.
| Factor | Weight | What it measures |
|---|---|---|
| Hourly probability | 40% | Peak and sustained chance of measurable rain across the next 24 hours. |
| Expected volume | 30% | Total millimetres, which separates a passing shower from a genuine soaking. |
| Timing & duration | 20% | When rain starts, when it eases, and the longest continuous dry window. |
| Local rain type | 10% | Drizzle, brief showers, thunderstorms or monsoon — each needs different gear. |

Summer is reliably dry and sunny. Autumn brings intense Mediterranean storms that can dump heavy rain in hours. A light jacket is enough June-September; proper rain gear needed for spring and autumn hiking.
No. Probability is the chance that at least 0.2mm of rain falls at your location at some point in the period. Check the expected millimetres alongside it: 40% with 0.4mm is a passing shower, 40% with 12mm is a soaking.
