Texas Spring Heatwave Is Not Unusual

May 15, 2022

By Paul Homewood


There has naturally been an attempt to blame the Texas power shortages on an “unusual heatwave”:





Fox is predicting temperatures to peak on Monday, at 101F in San Antonio and 96F in Houston:




Neither of these temperatures are unusually high for May.

In San Antonio, the record for May is 104F, set in 2004. There have been eight years since 1948, when temperatures hit 100F or more in May:



Across  in Houston, it is a similar story, with a record of 99F set way back in 1999. There have been thirteen years when May temperatures hit 95F and higher since just 1970:




Houston, we have a problem! But it is not global warming!

    My younger brother has lived in South Texas/Houston for 45 years, and knows that this kind of heat is not the least bit unusual for this time of year, in fact its normal service and people just get on with it, except of course for the many contemporary climate alarmists.

    True. The weather is not unusual. Ive lived here Houston on and off for 30 yrs. The issue is the state government. They have kicked all coal fired generation in to touch and replaced with wind. The margin between generation capacity and demand has been incrementally diminished while population has increased significantly (both out of staters and illegals). Another story about inept gov planning! The power system failure of Feb 21 has encouraged some better decisions of late but the pressures placed on the system by the intermittents is palpable.

    ‘Heat wave pushes Texas power demand toward levels rarely seen in spring’

    So f#$%ing what?

    They are going to have to deal with the heat in a month, anyway.

    As we saw in a previous post here, ‘as it confronts both unseasonably hot weather and six power generation facilities tripping offline . . . the facilities going offline Friday afternoon resulted in the loss of 2,900 megawatts of power.’

    The problem isn’t the weather, it’s generating capacity. These geniuses think the solution is to change the weather.

    “Don’t like the weather? Change it!”

    Bloomberg are stupid.

      Consider that brilliant apercu pinched! Well said!

    Going back to 1921 (and through 1940) NOAA’s NCDC was responsible for systematically (and seasonally) lowering the official US Weather Bureau monthly temperatures for almost all of the 48 states. Texas in May was no exception. A full one degree lower in 1921, slightly less in 1934, 1938 and 1940. Presumably record highs and lows were part of those adjustments.

      It’s called “homogenisation” apparently.
      I had a big argument on one of the climate science blogs with a programmer who insisted that it wasn’t deliberate scientific policy to mess with the temperature record, it was a product of the “AlGoreIthms”.
      I pointed out that as amongst other things I was a programmer going back to the mid-1960s and knew a bit about such things and my algorithms did as I told them, but it was a waste of time.

        If there are random errors, then averages wouldn’t change with adjustments as there’d be similar errors both ways – too hot and too cold.

        The fact they do change shows either there’s systematic error – but they haven’t identified that – or they are simply wrong.

        Or they are deliberate, more likely.

    Well, that same climate change must equally by responsible for the very unusual un-seasonal cold and wet we’re experiencing in the Pacific North West – some of us continuing to have to wear winter woollies in mid-May! All-time record cold temps registered this week at Seatac airport.

    Most certainly nothing exceptional. The mean of the Houston Max temps is 93.65;
    σ = 2.4, so the forecast of 96 degrees sits within one standard deviation of the mean.

      Ah but its averages that count as they are “normal”.

      We will destroy our economy based on our ignorance of basic statistics.

    Minor quibble.
    “Across in Houston, it is a similar story, with a record of 99F set way back in 1999.” should read 1996.

    I’ve been to Houston a few times.
