Navigating Precipitation: Rain, Snow, and More

Precipitation plays a central role in the West Windsor, New Jersey weather narrative, influencing everything from water resources to daily commutes. Understanding its patterns is key to preparedness.

Annual Rainfall Distribution

West Windsor receives a fairly even distribution of rainfall throughout the year, averaging around 45-50 inches (114-127 cm) annually. However, spring and summer months often see slightly higher totals due to convective thunderstorms and frontal systems. While consistent, heavy downpours can lead to localized flooding, especially in low-lying areas or where drainage systems are overwhelmed. We recommend monitoring local flood warnings during periods of prolonged or intense rain.

Snowfall Expectations and Variability

As mentioned, West Windsor experiences regular snowfall. The amount can vary significantly from year to year; some winters may see minimal accumulation, while others are hit with multiple large storms. While the average is around 20-30 inches, historic blizzards have brought much more. For instance, the West Windsor, New Jersey weather has been known to deliver over a foot of snow in a single event. The National Weather Service (NWS) provides excellent forecasts for snowfall amounts, which are crucial for planning travel and school closures.

Other Precipitation Types

Beyond rain and snow, West Windsor can also experience other forms of precipitation. Sleet, which occurs when snowflakes partially melt and refreeze into ice pellets, can make surfaces slippery. Freezing rain is perhaps the most dangerous, falling as liquid rain but freezing upon contact with surfaces, creating a glaze of ice that can be extremely hazardous for driving and walking, and can cause significant power outages due to ice accumulation on power lines. We've observed that preparedness for these less common but high-impact events is just as vital as for heavy snow.
