March weather forecast
Connecticut, USA

March marks a transition period in Connecticut's weather, moving from the chilling grasp of winter toward the more temperate conditions of spring. Average temperatures begin to rise, though they still reflect the coolness associated with the tail end of the winter season.

Snowfall becomes less common as the month progresses, especially in the southern and coastal regions. Inland and northern areas might still receive occasional snow, but generally, the amounts are reduced compared to the preceding winter months. Accumulated snowfall from previous months starts to melt, contributing to increased moisture levels.

Rainfall becomes more frequent in March, reflecting the shift from solid to liquid precipitation. The state averages between 44" (1118mm) to 48" (1219mm) of rainfall annually, and March contributes to this total with occasional showers.

Cold fronts from the Canadian North become less frequent, and while icy road conditions may still be encountered, particularly in northern regions, they are generally less severe than in January and February. Coastal fog continues to decrease in prevalence as temperatures rise.

The increase in temperatures also leads to a reduction in humidity, especially in the coastal regions, marking a shift away from the dampness associated with winter.

March's weather in Connecticut signifies a turning point in the climatic year, with a clear move away from the intensity of winter, paving the way for the more temperate conditions of spring. Variations between regions remain, with coastal areas experiencing milder weather compared to the more variable and sometimes still wintry conditions of the inland northern regions.
