Here's how often lightning strikes in Austin
After multiple storms swept through Austin this week, we're looking at how often lightning strikes around Central Texas.
Why it matters: Aside from the immediate danger to people, aircraft and infrastructure, lightning can spark wildfires — and the number of strikes is predicted to increase amid climate change, researchers have found.
By the numbers: Texas is one of America's lightning capitals, as it's home to all of the top 10 U.S. counties ranked by lightning strikes per square mile in 2024, per weather data firm Vaisala Xweather.
Walker County had about 825 strikes per square mile in 2024; Limestone County had 811; and Madison County had 795. All are along or close to I-45 between Houston and Dallas.
Yes, but: Things aren't as scary in Travis County, where there were about 145 strikes per square mile last year.
Reality check: Still, that's more than 150,000 strikes in Travis County in 2024.
One strike caused a house fire in North Austin this month, per CBS Austin. No one was injured.
Austin-area fire departments also responded to at least a pair of house fires sparked by lightning in a single night in March, per KXAN. No injuries were reported in those incidents, either.
Between the lines: Texas' lightning hotspot status isn't random — it's more prone to strikes as a result of consistent storms tied to its climate and geography.
How it works: Vaisala Xweather's data comes from sensors that use radio waves to detect and triangulate lightning strikes, with a claimed median accuracy of 84 meters (just under 300 feet).

Better weather, better Nelly: Korda shoots up board at ShopRite LPGA Classic with a 66
Better weather, better Nelly: Korda shoots up board at ShopRite LPGA Classic with a 66 Before we overanalyze the difference between Nelly Korda's game during Friday's opening round of the ShopRite LPGA Classic presented by Acer and where her game was in the second round, let's consider all the variables. Korda had four birdies and four bogeys en route to an even-par 71 on Friday, and followed with a sparkling 66 on Saturday. But when asked what was better, the world's best player had a pretty easy answer. "The weather was better," Korda said. "Wasn't as windy. We were playing in pretty gusty conditions yesterday and with the greens being kind of smaller already, it's tough to kind of judge your starting target with everything. Just makes it a little bit more difficult." "When the wind is down, you can be a little bit more aggressive." Korda was just that, posting three birdies on both the front and back to go with a single bogey on the par-4 12th hole at Seaview's Bay Course in Galloway, New Jersey. At 5 under for the three-day event, she's six strokes behind leader Ilhee Lee, but trending in the right direction. And after not taking part in this event for a few years, Korda is enjoying the crowds that come with the New York City-area event. "It's nice to see everyone come out and support. It's my favorite of part of what I do is kind of inspiring the next generation, seeing all the little girls and boys come out and support, not just me, but all of us out here," she said. "Definitely seen a trend in a really great direction even just with the fans that have been coming out. "It's great to see and great to play in front of as well."

Shade in Austin: Is it the same for everyone?
AUSTIN (KXAN) — While Austin ranks high for providing shade, some portions of the city could provide even more, especially as summer approaches, according to an organization that worked on a map to show what parts of the city have tree cover. Meteorological summer officially began June 1, and this means that temperatures in Austin, Texas, will only continue to rise and affect those spending time outside. The Shade Map, developed by American Forests and the UCLA Luskin Center of Innovation, indicates that Austin has approximately 33 million trees providing natural shade and cooling. This number places the city at a 92 on the Tree Equity Score, indicating strong overall tree coverage for the city overall. While this number is high, tree distribution is not necessarily equal across neighborhoods, meaning not everyone receives the same coverage, the study found. People can use the map to see how shady routes to school or work are. The map shows west Austin has more shade than east Austin. It also found most shade to sidewalks, in particular, comes from trees. How cool are trees? Austin tree canopy is growing 'Austin sidewalks get on average 30-60% shade over the course of a day – leaving residents in the full sun at least half the time when commuting to school or work. Even the lushest neighborhoods with extensive tree cover have only 49% shade at noon,' American Forests said in a release. According to the Shade Map, trees provide 300 times more shade than buildings at midday, highlighting the crucial role trees play in urban heat protection, according to Benita Hussain at American Forests. With temperatures frequently rising above 100 degrees in Austin, shade aids in preventing extreme heat exposure. Using the tree equality score feature on the shade map, Hussain urges the City of Austin to collaborate with organizations such as TreeFolks and the Austin Parks Foundation to fill in the gaps. Hussain also stated it is important to maintain and protect existing tree infrastructure and consider trees as 'living infrastructure' — not just greenery, but essential for urban health. Check pavement temperatures before walking your dog 'It's everything from protecting our current trees in those spots in addition to certainly planting more trees,' Hussain said. 'We want cities to say, 'Look. Look at the shade, look at the trees, and the cooling benefits,'' Hussain said. 'How do we invest in places that don't have enough trees? We don't have enough shade in order to meet what we see is a public health need across the city. What would it take to be able to address some of those areas that might be problem spots that have less tree cover?' Copyright 2025 Nexstar Media, Inc. All rights reserved.
