August saw Kenai Fjords’ temperatures return to normal and provided plenty of rain to ensure that, as is the fate of many good things, the lovely weather of summer 2013 had come to an end. After two months of above-average monthly temperatures, the monthly average temperature for August precisely equaled the 30-year average for the month, calculated from temperatures ranging from 44-69 degrees F at the Seward airport.
Considering the season as a whole, the Kenai Fjords area received more precipitation than normal this summer (see the monthly precipitation graph located in the next section of this report). From May-August the Seward airport recorded a total of 23.76 inches of precipitation, 9.56 inches above normal for these four months combined, amounting to 167% of normal rainfall. These numbers may conflict with the human perception of the fair weather we had this summer but reveal the significance and overall cumulative effect of individual rain events (such as were experienced and discussed in the July 2013 summary), as well as the consistent rain brought on in August when measurable precipitation was recorded on 22 days.
As recorded at the Seward airport, total precipitation for the month was 10.72 inches (191% of normal), 5.11 inches above the 30-year average (1981-2010) for the month.The monthly average temperature for July was 55.7 degrees F; equal tothe 30-year average. In general, winds were relatively calm throughout the month with maximum average wind speeds of 13.4 mph and a maximum wind gust of 25 mph, both recorded on August 3rd.
