Unseasonably warm and dry conditions persisted throughout the month of May providing an early start to the upcoming summer season. Both daytime and nighttime average monthly temperatures were above normal for the month and resulted in a new record high average monthly temperature of 50.9 degrees F, exceeding the previous record high May temperature of 50.6 degrees F set in 2004. New daily record high temperatures were recorded at the Seward airport on five days, May 1, 2, 9, 10, and 17. The 17th was the warmest day of the month, reaching 78 degrees F.
The warm and dry conditions allowed for an early start to the growing season but also allowed for a human-caused wildfire to take hold on the Kenai National Wildlife Refuge on the western part of the Kenai Peninsula. The total acreage burned exceeded 190,000 acres, making this the second largest recorded fire to burn on the Kenai Peninsula. Widespread smoke from this fire was observed in all directions on the Kenai Peninsula and beyond.
As recorded at the Seward airport, the monthly average temperature for May was 50.9 degrees F; 4.5 degrees above the 30-year normal. The total precipitation was 1.28 inches (38% of normal), 2.09 inches below the 30-year normal (1981-2010) for the month.
