Good to know
Good to Know
- Cancun remains beautifully warm year-round—the main choice is between peak-season prices (Dec-April) and hurricane-season discounts (June-Oct), not between good and bad weather.
- Hurricane season rain typically arrives as brief afternoon showers (10-20 minutes) followed by sun, not all-day downpours. Morning activities are reliably sunny even during peak rainy months.
- January-February and November offer the best combination: warm weather, minimal sargassum seaweed, and significantly lower prices than December peak.
- April-May provides excellent value—weather still warm and dry, sargassum just beginning to build, and prices drop sharply after Spring Break crowds depart.
- September-October offer the deepest price discounts (40-60% off peak season) if you book travel insurance with hurricane coverage and remain flexible on dates.
- Sargassum seaweed peaks June-August on Caribbean-facing beaches; November-March is seaweed-free. All-inclusive resorts manage it daily; independent hotels may be affected.
- Pack a light sweater or long-sleeve shirt for evenings December-February, especially during northerly wind events (el Norte) that can bring cooler nights to the low 50s-60s°F.
- UV index remains moderate-high year-round (6-7), so sunscreen and sun protection are essential every season.
