מזג האוויר בSayulita (Riviera Nayarit) במאי

May is the gap between two seasons and regulars value it for exactly that. The rains have not started - they arrive late May or early June and run to September - the heat has not reached its summer level, the crowds have gone, and the hotel rates drop from their high-season figures this month. The caveat is at the end: humidity starts building in the last weeks, and every week after that is worse. Our row shows the dry half plainly at 6.4mm across 0.9 days, with 32.1C reading as 37C and a 27.6C sea. Nights hold at 22.4C. It is usually breezy on the beach, and our 11.4 kph average says that breeze is light. The record: humidity 75 percent, 11.9 hours of sun and AQI 56.

Sayulita's forum draws a real distinction between the two halves of October: the first couple of weeks are still properly rainy season, with high heat, humidity and torrential downpours mostly overnight, while the back half of the month sees the heavy rain largely wind down even though it's still genuinely hot and humid. Posters pointed to late October into early November as a real sweet spot, once the worst of the humidity has broken. Warm, swimmable ocean water year-round is a constant regardless of which half of the month you catch.

Forum posters describe early April as one of the driest, most pleasant stretches of the year - mid-80sF days, mid-to-low-60sF nights, with no rain since the previous October and mosquito numbers correspondingly at their lowest. A cooling ocean breeze in the afternoon means posters recommend packing a light sweatshirt or pants even on an otherwise hot day. Posters contrast April favorably with February, noting shorts and short sleeves work fine in April versus needing light long sleeves and trousers earlier in the dry season. The one clear scheduling warning: Sayulita gets genuinely overwhelmed with domestic tourists during Semana Santa (Easter Holy Week), and posters consistently suggest avoiding that specific week if a quieter April visit is the goal.
