March was generally characterized by cooler than normal temperatures and above normal precipitation that came and went in a cyclical nature. Throughout the month, pulses of one-to-two day precipitation events delivered approximately 8-12 inches of snow following several days of sunshine each week. This weekly weather pattern increased the snowpack despite the clear sunny spells and lengthening hours of daylight provided by the onset of spring. Seward gained 2 hours and 34 minutes of daylight over the course of the month.
As recorded at the Seward airport, total precipitation for the month was 6.14 inches (139% of normal), 1.72 inches above the 30-year average (1981-2010) for the month. The monthly average temperature for March was 30.2 degrees F; 1.9 degrees F below the 30-year average. March 25th was the windiest day of the month reported at the Seward airport with sustained winds of 21.8 mph and a 5-second wind gust of 45 mph.
