Ithaca experiences a classic four-season climate in New York's Finger Lakes region, with distinct seasonal shifts that actually follow a pretty predictable pattern. Winters are cold and snowy (though the data shows minimal precipitation, Ithaca typically gets significant snowfall), with temperatures regularly dropping below freezing from December through March. Summers are comfortably warm rather than scorching, with July peaks around 29°C (84°F), making it pleasant for outdoor activities without the oppressive heat you'd find further south. The shoulder seasons are where Ithaca really shines, particularly late spring and early fall when temperatures are mild and the surrounding gorges and vineyards are at their most photogenic. Spring arrives gradually, with March still quite chilly but May warming up nicely to around 21°C (70°F). Fall is arguably the star season here—September and October offer that crisp, colorful upstate New York experience with comfortable temperatures and lower humidity than summer. Worth noting that the rainfall data provided seems unusually low for this region, which normally sees fairly consistent precipitation year-round, so you'll want to be prepared for rain in any season.

Best Time to Visit

Beach & Relaxation
Late June through August offers the warmest weather for enjoying Cayuga Lake beaches and swimming, with temperatures in the mid to upper 20s°C (70s-80s°F).
Cultural Exploration
May through October provides comfortable weather for exploring Cornell's campus, local museums, and the downtown commons without winter's harsh conditions or summer's occasional humidity.
Adventure & Hiking
Late April through October is ideal for gorge hiking and waterfall exploration, with May and September being particularly pleasant—warm enough for comfort but cool enough to avoid overheating on trails.
Budget Travel
January through March and November offer the lowest accommodation rates and fewer crowds, though you'll need to embrace cold weather and potential snow for the savings.
