Understanding Manhattan, MT's Unique Climate Profile

Manhattan, Montana, situated within the expansive Gallatin Valley, boasts a fascinating climate shaped by its specific geographical features. From our experience, expecting diverse conditions throughout the year is key to fully appreciating this area, which truly delivers on the promise of distinct seasons.

Geographic Influences on Local Weather

The most significant influencers on Manhattan's weather are the surrounding mountain ranges—the Gallatin Range to the east, the Tobacco Root Mountains to the west, and the Bridger Range to the northeast. These towering peaks create a rain shadow effect and channel prevailing winds, significantly impacting temperature and precipitation patterns. The Gallatin Valley itself acts as a basin, often trapping cold air during winter inversions, leading to much colder temperatures than higher elevations. Conversely, during summer, the valley can experience significant daytime heating. This unique topography results in a classic continental climate, marked by substantial temperature differences between summer and winter, and often between day and night. — Westerly, RI ZIP Codes: Complete Guide

Key Climatic Indicators: Temperature & Precipitation

Manhattan's climate is defined by its temperature extremes and varied precipitation. Summers typically see average high temperatures in the upper 70s to low 80s Fahrenheit (25-29°C), with nights cooling down considerably, often into the 40s or 50s Fahrenheit (4-12°C). Winters are significantly colder, with average highs in the 20s Fahrenheit (-6 to -1°C) and lows frequently dropping into the single digits or even below zero (-18°C or colder).

Precipitation is distributed throughout the year, with a slight peak in late spring and early summer from convective thunderstorms. However, a substantial portion of the annual precipitation falls as snow. According to data compiled from the National Oceanic and Atmospheric Administration (NOAA), Manhattan, MT receives an average of around 15-18 inches (380-460 mm) of precipitation annually, with annual snowfall often exceeding 50 inches (127 cm) and sometimes reaching 70-80 inches (178-203 cm) in heavier years.
