Austin reaches 100-degree day milestone as July declared earth’s hottest month on record

Weather Blog

Austin reached 103 degrees Thursday afternoon–the 24th time temperatures have reached the triple digits this summer. 24 days is the average annual number of 100-degree days since 1990, however since records began in Austin in the 1800s, 14 days is the long-term average. In a clear sign of continued global warming, since 1998 the average number of 100-degree days in Austin has climbed to 34.

And, Central Texas is not alone. NOAA confirmed what we reported with preliminary data last week– last month was the hottest month on earth since at least 1850. July 2019 marked the 415th straight month that was warmer than the 20th-century average.

Both Arctic sea ice and Antarctic sea ice were at their lowest levels on record for the month, missing a total of 1 million square miles of ice, according to NOAA..
