The problem is it has been never ending this summer in San Antonio, and it's not a dry heat like say the Arizona or California deserts. Not trying to say it's worse than what Phoenix had last month by any means, but it's not the same as 40C would be there either. It was quite humid today and our heat index was 110F = 44C thanks to a 67F = 19.4C dewpoint whereas with a more desert like 45F = 7.2C dew point like say Barstow, CA has right now you'd be talking about a heat index of only 100F = 38C at 104F = 40C. And it has been like this for ten straight days now and we have been above 100F = 38C for 37 of the last 39 days, with the other two being 99F = 37.2. 40C for more than a week and a half in a non desert climate sucks hard. This area is only supposed to get 19 days of 100F = 38C per year on average and we're at 48 right now with 18 days of the hottest month remaining. Hell we have had 14 days of 105+ this year when our previous record was 4. This is not the kind of climate that should be getting to 40C regularly. It's a humid grassland, not a desert area.
