Weather by Season

Winter

Winter at Letchworth State Park brings cold, shorter daylight, and periodic snow or ice. Snow and ice can support the listed winter activities, but conditions and access must be confirmed locally.

Spring

Spring is changeable, with rain, mud, snowmelt, rising water, and lingering ice in shaded or elevated terrain. Lower routes and developed facilities generally become usable before exposed, backcountry, or high-elevation areas.

Summer

Summer usually provides the broadest access, but heat, humidity, thunderstorms, crowds, and occasional wildfire smoke can alter plans. Start exposed outings early and keep a weather-safe turnaround point.

Fall

Fall brings cooler air, foliage crowds, shorter daylight, and increasing wind. Early snow or ice can reach northern and elevated areas while lower valleys and coastal destinations remain milder.

Key Climate Data Points

  • Annual average temperature: around 44–48°F, using the relevant local and elevation context.
  • Annual snowfall: commonly 70–130 inches, with sharp lake-effect differences.
  • Warmest months: July and August are normally warmest.
  • Coolest months: January is typically coolest, with February similarly cold in northern and elevated areas.
  • Wettest season: precipitation is distributed through the year, with late spring through summer often wettest from rain and thunderstorms.
  • Driest season: no season is reliably dry statewide; early fall often provides the most stable outdoor windows.
  • Best outdoor window: June through October for warm-season access, with midwinter best only where established winter recreation is supported.
