Quick answer
January to March is the best all-round time for Cancún: dry, warm and usually little seaweed. November and early December are a close second and often cheaper. June to September is the riskiest time, as peak sargassum season overlaps with the Atlantic hurricane season (1 June to 30 November).
How do the months compare?
| Months | Seaweed | Storm risk | Verdict |
|---|---|---|---|
| Jan–Mar | Usually low | None | Best overall, busiest |
| Apr–May | Rising | None | Good, check seaweed reports |
| Jun–Aug | Peak | Hurricane season | Cheapest, highest risk |
| Sep–Oct | Easing | Highest (September) | Deals, but get insurance |
| Nov–early Dec | Usually low | Season ends 30 Nov | Great value |
How do you avoid sargassum?
- Stay on the Cancún Hotel Zone's north-facing beaches or Isla Mujeres, which are often less affected than the Riviera Maya further south.
- Check a live seaweed report a few days before you go.
- Pick a resort with a pool you'd enjoy anyway.
What if you travel in hurricane season?
- Buy travel insurance as soon as you book, before any storm is named.
- Choose refundable hotels.
- Know what you are owed if your flight is cancelled: see our flight delay guide.
