All-time Austin heat record tied

August 23rd, 2011 at 1:00 am by under Weather

Prior to 2009, we often wondered whether Austin’s  heat wave records from the 1920s were really accurate. After all, we’d never even been close to experiencing 66 days of triple digit heat, as recorded in 1923, much less the 69 day record from 1925. In fact, until we recorded 50 days in 2008, the closest we had come was 42 days back in 2000.

The summers of 2009 and 2011 have put the matter to rest. Monday’s record-tying high of 105 degrees was the 68th time this summer the high reached 100 degrees or hotter, equaling 2009′s number.

The all-time record of 69 days was tied early Tuesday afternoon as the temperatures topped 100 degrees again, and Wednesday will become the 70th day–a new all-time record for Austin.  Unfortunately, the record will only last one day, because we are forecasting triple digit highs into early next week, meaning a new record will be established every day.

Here’s more information from the National Weather Service:

    All this unbearably hot weather has gotten quite depressing in my opinion.

    On a related note, I just read that the forecast for this upcoming weekend is now calling for much hotter weather. Only a day or so ago, the thought was that the upper level ridge would be moving to the four corners area, which would lead to somewhat milder weather (albeit still around 100). Now, the NWS forecasters are saying the ridge still will move westward, but it’s supposed to be even hotter! What’s changed?

    I am still curious whether you guys ever actually reported anything on the inaccuracy of the 1920s records. Just today I went looking again and found that the NCDC site doesn’t actually record WHERE the thermometer was for the 1920s ‘heat wave’ – only that it moved to the UT campus in 1926, coincidentally when the extreme heat readings suddenly stopped.

    Also noticed in their data that the daily maximum minimums (highest nighttime lows) have no datapoints from the 1920s in them at all. Wouldn’t this data, combined with the nowhere-near-historic heat in San Antonio during those years suggest a bad thermometer placement for at least the first half of the 1920s?

  3. RKM says:

    Any word on when it’s going to drop? We’re all a little desperate for some cooler days, and I can’t find any info about any end in sight.

    1. Bob says:

      I’d like to add my voice to the group who’s wondering when this is going to quit? Would it be possible to bracket it?

      Something like “superhot until at least Sept. 3, then just very hot until Thanksgiving”

      Just looking for a date to look forward to.

  4. Dry Line says:

    The State Climatologist’s reports for 1923 and 1925 do NOT back the claims that Austin or the state suffered through heat waves like the ones in recent years.

    Austin is not mentioned in either report. The first line of the 1923 report states: “The state-wide mean temperature was close to average but the precipitation showed a very large excess in all regions.”

    The state report for 1925 begins: “The year was warmer and drier than average. Two months, April and July, were the warmest ever for those months.” Clearly 1925 was not a calendar cover in Texas, but the State Climatologist’s report suggests it was nothing like 2011.
