Ithaca, located in New York's Finger Lakes region, experiences a classic four-season continental climate with significant seasonal variation. Winters (December-February) are cold and snowy, with temperatures regularly dropping below freezing, while summers (June-August) are warm and pleasant with temperatures reaching the upper 20s°C. The city receives relatively consistent precipitation throughout the year, though the data shows notably low rainfall amounts that likely represent snowfall in winter months converted to liquid equivalent. Spring (March-May) brings a gradual warming with temperatures climbing from near freezing to comfortable mid-20s°C, while fall (September-November) offers spectacular foliage as temperatures cool from summer highs back down to winter lows. The shoulder seasons of late spring and early fall are particularly attractive for visitors, offering mild temperatures and beautiful natural scenery. Humidity remains fairly consistent at 70% year-round, contributing to the area's lush greenery during warmer months.

Budget Travel
