Although the below-normal temperatures experienced in March continued into April, the previous precipitation pattern ceased, resulting in little new rain or snow in the Kenai Fjords area. Measurable precipitation was recorded at the Seward airport on only two of the thirty days. Despite very little new precipitation, 50 inches of snow remained on the ground in the Exit Glacier area at the end of the month, the likely result of cool temperatures that impeded snowmelt. Daylight continued to lengthen as Seward gained 3 hours and 33 minutes of daylight over the course of the month.
As recorded at the Seward airport, total precipitation for the month was 0.69 inches (15% of normal), 3.83 inches below the 30-year average (1981-2010) for the month. The monthly average temperature for April was 33.5 degrees F; 5.2 degrees F below the 30-year average. April 8thwas the windiest day of the month reported at the Seward airport with sustained winds of 23.5 mph and a 5-second wind gust of 47 mph.
