Overview of Praslin’s Summer Climate
On Praslin Island, summer means steady warmth, high humidity, and frequent rain showers. Daytime temperatures sit in the upper 20s to low 30s °C (low to mid-80s °F), and sea breezes take the edge off the humidity.
Rain happens often, but the sun usually comes back not long after. Praslin has a tropical climate, so summer weather stays warm and humid.
Showers show up a lot during this season, often in the afternoon or evening. They might be heavy, but they tend to move through quickly, leaving blue skies behind.
You’ll notice a mix of sunny and cloudy days. Even in the wetter weeks, Praslin still gets several hours of sunshine daily.
Winds usually stay light to moderate, but they can pick up during storms. The sea keeps warm, averaging around 27–29 °C (81–84 °F), which is perfect for swimming and snorkeling.
Sometimes, though, heavy rain can make the water a little murky. Visibility drops after big showers because of runoff.
Seasonal Temperature Patterns
Daytime temperatures in summer usually range from 28 °C (82 °F) to 31 °C (88 °F). Nights cool off just a bit, often staying between 24 °C (75 °F) and 26 °C (79 °F).
This narrow range comes from the island’s spot near the equator. The hottest stretch usually hits between March and April, with daytime highs at their peak.
July and August feel a bit cooler, but honestly, it’s only by a couple degrees. Since it rarely gets chilly, you won’t need warm clothes.
Pack lightweight, breathable fabrics—they’re your best bet. Most hotels and guesthouses have air conditioning or ceiling fans to help you sleep comfortably.
