November is here and colder mornings are right around the corner. John Lopez of Austin was wondering when the area normally receives its first freeze of the season.
Some areas of the western hill country have already dropped into the freeze zone during the last week of October. That is a little early. Normally Austin gets the first freeze early in December. However, the hill country is more likely to get the first frost early in November and areas south and east of Austin freeze late in November.
In 1924, Austin had its earliest freeze ever with a low coming in at 31 degrees on October 26th.
The number of freezes continues to decrease in Austin because the city has grown so much in the last 20 years. It has become an urban heat island. All the concrete radiates more heat producing a warmer bubble around the city.
In the last 30 years temperatures on average have dropped to freezing levels in Austin 25 times per year compared to 45 for parts of the hill country.
Another cold front arrives next week giving parts of the area a slight chance of a light freeze but overall the temperature outlook for November shows warmer than average weather continues.
