March weather forecast and climate
Connecticut, USA

March is cold in Connecticut, with the transition from winter to spring in the second half of the month. The average high temperatures are in the cold 45°F (7.2°C) to 50°F (10°C) range, while the average low temperatures are in the freezing zone of 22°F (-5.6°C) to 32°F (0°C). Mornings dawn with a promise of sunny afternoons, but frequently fade into cold evenings and frosty nights.
The snow covers the ground in the interior, while the coast rarely sees a frozen landscape. Precipitation is to the tune of 3" (76mm) to 5" (127mm), and the snowfall in the range of 5" (127mm) to 8" (203mm) attracts many followers. New Haven along the coast registers temperatures between 31°F (-0.6°C) to 48°F (8.9°C), while Burlington in the interior is cold between 26°F (-3.3°C) to 47°F (8.3°C).
Winter coats are very much in vogue as cold fronts from the Canadian north routinely make way to the interior. The daylight improves steadily as the spring season knocks the doors of Connecticut in late March.
