If you think this June has so far been cooler than the past few, you’re not alone, and you’re generally on the right track.


National Weather Service meteorologist Andrew Woodcock mentioned it this morning in his forecast discussion, and it got me thinking, so I dug a little deeper to compare the past five Junes, and I wanted to take a peek at the long range forecast for the rest of this month.

So far this June at Reagan National Airport (DCA), there have been only two 90 degree days with the warmest temperature being 91°. Compare that to 2012 when there were three 90 degree days by the 17th, but there were eight during the second half of the month for a grand total of eleven. Also, keep in mind that there was some serious heat during June 2012 with the warmest reading being 104° on the 29th.

Below is a table of the previous 5 Junes. Of note: June 2010 had eighteen 90 degree days, so over half the month featured highs at or above 90° with a maximum temperature of 100° on the 24th. Conversely, what a relief June 2009 was with only two 90 degree days and a maximum of a mere 91°.

June Comparison

So what’s ahead for the rest of the month? Well, for the rest of this week, I think we’ll have only one shot at a 90 degree day, and that’ll be tomorrow. Also, Sunday and into the final week of June I think we have the potential to come close to 90° for a few more days, and should DCA hit 90°, I doubt it’ll exceed it by much. The Climate Prediction Center has the D.C. area within an increased chance of above average temperatures through the end of June, but no major heat seems to be in the works for the final two weeks of June for the Washington area. That doesn’t mean that it’ll be cool with below average temperatures – I’m just looking at 90 degree day potential.
