July outlook: D.C.'s hottest month to play the part.

We lean toward conditions being slightly hotter and wetter than average.

As we set foot into what’s typically our hottest month of the year, we may be able to use the past 30 days as a guide as to what to expect. June has been slightly hotter and wetter than normal, which is where July appears to be headed as well.

The 30-year (1991 to 2020) average temperature in July is around 81 degrees, and we estimate an outcome between 81 and 83 degrees this year.

Average rainfall is 4.33 inches, and we’re forecasting 5 to 6 inches this July.

Models project a hot, humid and stormy first half

July will start out much the same way June performed, with variable temperatures that average out to the hotter side and intermittent periods of heavy rainfall. While the upcoming holiday weekend leans cool, the overall two-week forecast from the various model simulations, as shown below, features slightly hotter than normal temperatures and above normal precipitation. >>>
