RICHMOND, Va. — September 2016 started off with some wet days, but we had a prolonged period of dry weather in the middle part of the month. That ended by the final two weeks as two different storm systems dumped bouts of heavy rain across the area. The first was from the remnants of what was Tropical Storm Julia, and the second one was from a stagnant area of low pressure located to our west.
The total for the month exceeded 11 inches, which was more than seven inches above normal. We set a new record rainfall on September 28 of 4.74″. Other portions of Virginia saw even higher rain totals. During the final week of September, some areas south and east of Richmond received over ten inches of rain.
Some rain fall on just over half of the month (53% of the days). The month ended up being the second wettest September on record, and the 11th wettest month ever in Richmond weather history. Rainfall records for Richmond date back to 1872.
And although we had some cooler days across the month, September ended up being 3.4° above normal. The daily highs averaged out to 82° and the lows averaged out to 66°. The hottest temperature was 94° on September 9, and the coolest temperature was 58° on September 5. Cooling needs were about 40% above normal for a typical September.
