January delivers 323% more rain than July (338mm vs 80mm). 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 Seychelles is spread through the year — there is no season you can rely on being dry.
Seychelles rain typically comes as discrete showers, so a compact umbrella and a flexible plan are usually enough.
Rain falls on about 21 days in January against 5 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 Seychelles 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. |
