Cancún is warm year-round — that's the whole business model — but three overlapping calendars decide whether a trip feels ideal or merely fine.
The dry season (roughly November to April)
This is peak season for a reason: lower humidity, minimal rain, and the most reliably calm, clear water. It's also when prices and crowds peak, especially around Christmas/New Year and North American spring break in March.
The wet, hot season (May to October)
Expect short, heavy afternoon downpours rather than all-day rain, alongside real heat and humidity. Mornings are often clear. This stretch overlaps with hurricane season and generally lower hotel rates.
Hurricane season (June 1 – November 30)
Officially the Atlantic hurricane season runs these six months, with the highest statistical risk from August through October. Direct hits on Cancún itself are infrequent, but tropical storms and indirect effects (rain bands, rough surf) are common enough to plan around if you're traveling in late summer. Always check the season's outlook and any active storm tracking a week or two before you fly.
Sargassum season
Sargassum is the brown seaweed that periodically washes up on Caribbean-facing beaches. It tends to be worst from roughly April through August and lighter outside that window, though the amount varies significantly year to year and isn't fully predictable. It affects beaches unevenly — the Hotel Zone's northern beaches (facing Bahía de Mujeres) are typically calmer than the east-facing Caribbean beaches. See our sargassum update page for the current picture.
🗓️ Our take
Late November to early December, and again in April right after Easter week, tend to offer the best balance: good weather, lighter sargassum, and prices that haven't hit peak-season levels yet.
