Todos Santos has two seasons: the dry, mild winter (November through April) and the hot, occasionally stormy summer (May through October). The best months are November through March, when daytime temperatures stay in the mid-twenties, the surf is consistent, and the town is at its most active socially and culturally.
July and August bring heat and humidity, and the occasional late-summer hurricane. The town quiets down and some restaurants close or reduce hours. Late October sees a rush of returning residents and the beginning of the art season.
The Festival de Arte, usually held in late October or early November, is the liveliest cultural event of the year.
