מזג האוויר בSayulita (Riviera Nayarit) בפברואר

February sits squarely inside the humpback season here, which regulars date precisely - roughly the 8th of December to the 23rd of March, with the whales in Banderas Bay through to April - and January reports describe breaching offshore all day. On weather they mostly say February is fantastic, with one dissenting account of a first week of heavy rain and the mountains lost in cloud; our row's 19.9mm across 2 precipitation days says the usual case is the dry one. The number worth checking before packing swimwear is the sea: 24.8C here, noticeably cooler than the Mexican Pacific further south, because this is a winter bay. The record: 29.3C reading as 33C, 18.1C nights, humidity 79 percent, 10.2 hours of sun and AQI 31.

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.
