Much as already been made regarding the breaking of the record for consecutive 70-degree days for Anchorage. Today is day number 14 in a row and the forecast for the next several days indicates that the record will be extended. What has not been noted anywhere is that the last two weeks has been the warmest two week period ever measured in Anchorage when looking at the average daily temperature. Here is the list:
14-Day Ave Temp Date Range Rank
64.96 7/17/2013 - 7/30/2013 1 * (minor edit on 7/31)
64.89 7/7/2003 - 7/20/2003 2
64.82 6/20/1953 - 7/3/1953 3
64.75 7/18/1936 - 7/31/1936 4
In addition, Anchorage (and Fairbanks) are closing in on their warmest summer-to-date records. Here is an update of the chart uploaded a few days ago.
Note: Each of the thin lines represents the cumulative average temperature for the summer season at a specific point in the season for the 10 warmest summers on record. Here is an example of how it works.
Date Temperature Season-to-Date Temp. Calculation
June 1 66 66.0 66 / 1
June 2 62 64.0 (66+62) / 2
June 3 71 66.3 (66+62+71) / 3
June 4 67 66.5 (66+62+71+67) / 4
June 5 65 66.2 (66+62+71+67+65) / 5
At the beginning of the summer there is a lot of variation since the value in the denominator is small. Over the course of the summer the lines tend to converge.
