Optimal Weather: December-April. Dry season, 25-28°C, minimal rainfall. Peak season pricing and crowds expected.

Best Value: May and November. Shoulder seasons with excellent weather, reduced hotel rates. May reaches 32°C+ but ocean breeze makes it manageable.

Hurricane Season Reality: June-October. August-September are peak months, but most storms miss Cancún entirely. Hotels offer excellent last-minute deals. Travel insurance essential.

Avoid: March (spring break chaos) and December 15-January 5 (premium pricing, maximum crowds). If visiting during spring break, advance reservations critical.

Important: Check sargassum seaweed forecasts before booking. Can wash up April-August making beaches unswimmable. Compares unfavorably to Caribbean destinations like Barbados which rarely experience seaweed issues.
