CWG readers predict 42 90+ days in Washington, D.C. by the fall

Distribution of predictions for 90+ days from Capital Weather Gang readers
More than 200 readers entered our game to forecast the number of days that will reach 90 or higher at Reagan National Airport between May 1 and October 15. The average number predicted was 42 (also the median).

This number is slightly lower than Capital Weather Gang’s prediction of 45-50. The range of submissions spanned 4 to 105. Since 1980, the most 90+ days to occur was 68 in 1980 and 2010, and least was 11 in 2004.

The above chart displays a histogram which gives a good general sense of the grouping of predictions.

Interestingly, reader forecasts had a tendency to fall into a range either just above (41 to 50) or below (21-30) the historical average number of 90+ days, rather than average itself - which is 36 (or between 31-40).
