Month-by-Month Guide
January
The coldest month in Ithaca, with temperatures hovering around freezing and typically significant snowfall (despite the low precipitation reading in the data). The gorges can be stunning with ice formations, but many trails close for safety. It's quiet around town when Cornell students are on winter break.
February
Still firmly winter, though days are getting noticeably longer. Temperatures remain below or just above freezing most days. This is typically one of the snowiest months, so the surrounding hills and gorges can look quite dramatic if you're prepared for the cold.
March
The transition month where winter starts loosening its grip, though you'll still get snow and freezing temperatures, particularly early in the month. By late March, you might catch the first hints of spring, but it's unpredictable—could be 15°C one day and snowing the next.
April
Spring finally arrives in earnest, though it's the cool, muddy kind of spring. Waterfalls are typically at their most powerful from snowmelt, and you'll see the landscape green up considerably. Temperatures are mild but you'll still want layers, especially in the mornings and evenings.
May
One of the nicest months in Ithaca, with comfortable temperatures and the landscape in full bloom. The gorges are spectacular, and it's warm enough for most outdoor activities without summer's humidity. Cornell's graduation brings a temporary crowd surge mid-month.
June
Early summer brings consistently warm weather and longer days, perfect for exploring the wine trails and hiking. Humidity starts picking up but isn't oppressive yet. Tourist season is ramping up, particularly on weekends, as people flock to the gorges and Cayuga Lake.
July
The warmest month, though at 29°C (84°F) it's pleasantly warm rather than sweltering. This is peak summer tourist season, so popular spots like Taughannock Falls and Buttermilk Falls can get crowded on weekends. Good weather for swimming in the lake and outdoor festivals.
August
Similar to July but with slightly higher rainfall (though still quite low). Warm days and comfortable evenings make this ideal for outdoor dining and evening walks. Students start returning toward month's end, bringing more energy to the downtown area.
September
Early fall brings some of the year's most pleasant weather—warm days, cool nights, and lower humidity than summer. The college town vibe returns in full force. By late September, you might catch early fall colors, particularly at higher elevations around the area.
October
Peak fall foliage season, with spectacular colors throughout the region—this is when Ithaca looks like a postcard. Temperatures are crisp and comfortable for hiking, though you'll need layers as mornings can be quite cool. Weekends get busy with leaf-peepers.
November
Late fall transitions toward winter, with temperatures dropping considerably and the landscape turning gray and bare. Early November can still be pleasant, but by month's end you're looking at near-freezing temperatures and possibly the first snow. Crowds thin out significantly.
December
Winter sets in with cold temperatures and typically snowy conditions (though precipitation data seems low). The holiday season brings some festive atmosphere downtown, but it's generally quiet. Many outdoor attractions have limited hours or close for the season.
