Clima em Beau Vallon (Mahé) em maio

Praslin-forum threads on May specifically call out the seaweed situation on Cote d'Or: the trade winds typically shift direction in April, and by May the beach is usually clear again, crystal water and none of the seaweed buildup that can affect it earlier in the year. The same clearing effect is described for Anse Georgette, Anse Lazio and Anse Source d'Argent, all called seaweed-free bets by May. The southeast trade winds pick up starting in May, running through September, though posters say the month isn't yet at peak windiness. Forecasts here are called notoriously overcautious, one visitor reporting an entire May stay without a single wet day despite regular rain predictions. May and October are grouped as similarly moderate rainfall months, May the hotter of the two. The record: 27.9C days feeling like a sticky 32C, 26.4C nights, a notably high 207mm across 20.2 days, 81 percent humidity, a 29.7C sea and 10.1 hours of sun.

Seychelles forum threads are consistent that January is the rainiest month of the year, and Beau Vallon specifically - on the northern side of Mahé - tends to see more rain and cloud than the island's southern coast, thanks to the northwest trade winds pushing cloud masses in this time of year. Despite that, posters were clear this isn't monsoon-style all-day rain: a typical day mixes real sunshine with rain showers, and most visitors get at least a few solid beach hours daily even in the wettest stretch. The general advice: expect a genuine mix of sun, cloud and rain rather than betting on either extreme.

Forum posters describe mid-March visits as mainly sunny and hot with the occasional full rain day mixed in - Seychelles weather is repeatedly called genuinely unpredictable, with posters noting the islands have real micro-climates that can make conditions differ from one side of Mahe to the other, so no forecast covers every variation. The specific seasonal issue for Beau Vallon in March is dead seaweed washing up on the beach, a recurring nuisance posters say clears up by late April into May, when the ocean also turns calmer with better visibility as temperatures and humidity start to ease. For travelers prioritizing clean sand and clear water over slightly warmer conditions, posters suggest that later window is the better trade-off.
