ヴィクトリア 8月の天気

August is the roughest month of the Seychelles year and the cause is the south-east trades: July and August bring the strongest of them, with choppy water and the poorest snorkelling of the year, especially on a beach that faces into it. The same wind moves seaweed - on Praslin it piles up on Grand Anse and Anse Kerlan, and on Mahe along the south and south-west coasts. The forum's answer is a coast rather than a month: Cote d'Or on Praslin and Beau Vallon on Mahe stay clear and clear-watered, and carry the shops, restaurants and agencies as well. Our row has the wind at 30.6 kph. The record: 25.5C days that feel like 28C, 24.6C nights, 12.2 precipitation days carrying 61.8mm and a 26.6C sea.

Forum posters describe September as generally falling within the Seychelles' quieter, more settled season, though posters are consistent that no month here is fully predictable given the tropical setting - It is worth noting that Victoria's own 12-month climate record does not actually show September as a dry month - February and August run considerably drier (around 12-13 rainy days each versus September's roughly 19), with September's rainfall total among the higher months of the year rather than the lower. Posters flag rougher ocean conditions and stronger currents as a real September consideration at some beaches, improving into October once winds shift and settle from southeast to northwest, bringing calmer water and better snorkeling visibility. Posters generally rate September as a workable but genuinely wetter choice for Victoria than the forum's "dry season" label suggests, with October the better-supported pick for calmer water and lower rain.

Forum posters describe March as the tail end of the Seychelles' rainy season (driven by north-west winds), with rain generally less frequent than February - typical showers are short, stormy 10-15 minute bursts followed by a return to sun, rather than sustained all-day rain. Posters are consistent that hot and humid conditions define the month regardless of the rain, with one mid-March visitor reporting mostly sunny, hot weather with just one full rain day mixed into an otherwise clear stretch. By late March specifically, posters say shifting winds bring genuinely improved weather and calmer seas, meaningfully reducing rain odds compared to earlier in the month. One regional nuance: posters note the higher-mountain islands see more rain than flatter ones, making nearby Praslin or La Digue a slightly drier alternative to Mahe (where Victoria sits) if minimizing rain risk matters.
