March is the comfortable end of the Puerto Vallarta season on the forum's account: warm days in the low 80s F, cool mornings and evenings early in the month, humidity lower than it will be all year and the odd breezy day. Two dates decide a March trip. Whale season officially runs 8 December to 23 March, so an early-March visit is inside it and a late-March one is picking up strays. And the busiest week of the year is the one either side of Easter, which can land in March - the first fortnight is described as busy but not overwhelming. The record: 29.8C days that feel like 34C, 17.7C nights, 0.2 precipitation days in the whole month, 11.1 hours of sun, a 24.8C sea 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.
