Frequently asked questions about Austin's climate
Is Christmas getting warmer in Austin?
The average high temperature during Christmas week, December 20 to 27, was 15.1°C in 1976 to 1986. In 2015 to 2025 that same week averaged 19.1°C. A rise of 4°C over the exact same week of the year.
How many tropical nights does Austin get now?
Austin averaged 152 nights a year that never cooled below 20°C in 2015 to 2025, up from 135 in 1976 to 1986. A night like that is the main reason sleep gets worse during a heatwave, the body can't cool down enough to reach deep sleep.
How long do heatwaves last in Austin now?
The longest unbroken run of exceptionally hot days now averages 15 days a year, up from 7 days in Austin's own early record. The threshold is Austin's own 95th percentile hot day from the 1976 to 1986 window, not a fixed number for every city, so this measures how the city's own definition of too hot has shifted, not just how often it crossed some fixed temperature.
Is the pavement too hot for dogs in Austin?
On 224 days a year now, the temperature passes 25°C, hot enough that asphalt or sand in full sun reaches roughly 52°C, the point vets say a dog's paw pads start to burn within about a minute. That's up from 200 days in the 1976 to 1986 window. The simple test, press the back of your hand to the pavement for seven seconds, if that's too hot for you, it's too hot for a dog.
How hot does a parked car get in Austin?
Austin now has 287 days a year warm enough, above 20°C, for a closed car in the sun to get hot enough to melt chocolate left on the seat, up from 272 in the early record. A closed car reaches that point within about an hour, which is also why leaving a child or a pet alone in the car, even briefly, is dangerous on far more days than it used to be.
Are dry spells getting longer in Austin?
The longest unbroken run of days with under 1mm of rain now averages 28 days a year, up from 26 in 1976 to 1986. Longer dry spells matter for sprinkler bans and cracking in clay soil foundations.
Is insect season getting longer in Austin?
The warm season here, days averaging above 10°C, is now about 5.5% warmer than in 1976 to 1986. Under the Q10 rule from biology, insects and mosquito larvae develop roughly twice as fast for every 10°C of warming, so this difference translates into noticeably faster breeding cycles, one reason insect season starts earlier and runs longer than it used to.
