AUSTIN, Texas — According to a tweet from the National Weather Service on Tuesday, Aug. 8, neither Austin nor San Antonio has experienced a day with daily average temperatures below normal in a full two months.
When averaging out the daily high and low temperatures from each day since June 8 at Camp Mabry, every day has been above the normal daily value. The normal daily value is also an average, but the average over a 30-year period, rather than just one day.
Even on days this summer when the high-temperature value for a given day was below average, the daily average still remained above.
July 6 was our only "below average" day last month, with 92 as our official high temperature. However, the low for that day was 78, giving us a daily average of 85 degrees. The normal daily average, or climatological average for July 6 is just 0.1 degree below that, at 84.9°F.
So yes, technically, we have been above average almost all summer long. Remember meteorological summer began on June 1.
The first eight days of June had daily averages below or at normal. This was the tail end of generally normal springtime temperatures Austin endured throughout May.
The 2-month long streak of above-average daily temperatures is likely to continue through August if our upper air pattern remains the same. So far, the "heat dome" didn't wobble much throughout July, and it is forecasted to stay more or less stagnant through August.
Either the upper-level pattern changes or a tropical depression is able to move inland and relieve Central Texas from some heat.
Apart from the above-average temperatures, our current streak of consecutive triple-digit days is now at 33 as of Wednesday. The overall number of triple-digit days for the summer of 2023 stands at 48.
