Chatham & Monomoy Weather by Season

Winter

Charter and refuge access diminish while nor’easters reshape bars, beaches and navigation channels.

Spring

Cold water, fog and shifting shoals complicate the return of boating before summer services stabilize.

Summer

Tide, wind and thunderstorms control safe harbor exits; official wildlife guidance governs beach access.

Fall

Tropical swell can alter inlets before cooler, calmer periods return between early coastal storms.

Key Climate Data Points

  • Local climate: Lower Cape marine climate; annual mean temperature about 51–53°F; roughly 45–47 inches precipitation; around 25–35 inches snow; navigation conditions can change after major storms.
  • Warmest period: August carries the warmest air and water, though ocean fog and northeast wind can cool the outer shore abruptly.
  • Coolest period: January is coldest, with few sheltered options on beaches, flats and refuge approaches.
  • Primary storm or hazard season: Shoaling, strong current, rip currents, fog, tropical swell and nor’easters can change launch or refuge access quickly.
  • Best general outdoor window: July through September is the most practical marine window, tempered by wildlife protections and same-day small-craft conditions.
