I’ve been in Texas (in the Dallas area) for over 30 years, and this seems to be one of the strangest summers I can remember; specifically, in July and in August, it has been cool enough in the evenings to open the windows because the temperature dropped to the mid-60s. That is certainly atypical; normally, when it gets hot toward the end of May, the windows get closed, and stay closed until late in September. But twice now, because of what they call a “polar vortex”, the temperatures have dropped and we’ve had a few days of very nice weather.
