All Months
April through October offers the best weather, but each season brings trade-offs. Summer means warmest temperatures but thickest crowds and highest prices. The aquarium sells out weekends, and good restaurants require reservations.
Shoulder seasons — April-May and September-October — deliver ideal conditions. Fewer tourists, lower hotel rates, and clearer skies before summer fog sets in. Water temperatures peak in September and October, making it prime time for kayaking.
Winter brings whale migration season from December through April. Gray whales pass close to shore, and you'll spot them from 17-Mile Drive or whale watching boats. Just pack rain gear — Monterey gets most of its 20 annual inches between November and March.
Here's the thing about Monterey weather: it changes fast. Morning fog burns off by noon most days, revealing sunny skies. But temperatures rarely break 75°F, even in August. Always bring layers and closed-toe shoes for evening walks.
