The NASCAR season opens Sunday with the 68th edition of the Dayton 500 at Daytona International Speedway. The broadcast starts at 12:30 p.m. ET and the green flag is at 2:30 p.m. ET (FOX and the FOX Sports app). What does the weather look like? Sunday’s low is 59 degrees and the high is 78, according to FOX Weather. There’s a 41% chance of rain, slated to pour between 1 p.m. ET and 4 p.m. ET, so it could potentially disrupt the race. There are also winds heading south at 16 miles per hour. The sun will set at 6:14 p.m. ET.

There were two delays that totaled more than three hours and 30 minutes until William Byron ultimately won the race. Rain has also already been a story for the 2026 season of NASCAR. The Clash at Bowman Gray, the exhibition race last Wednesday, took three and a half hours to complete, and included 17 caution flags, and dicey racing on a wet track.

But skies should be clear for the remainder of the race week and weekend, from Wednesday through Saturday. That includes Practice 1 on Wednesday, Feb. 11 at 10 a.m. ET and qualifying on Wednesday at 8:15 p.m. ET. Then on Thursday the cars are split into two duels — Duel 1 is at 7 p.m. ET and Duel 2 starts at 8:45 p.m. ET. Practice 2 will be held Friday at 5:35 p.m. ET. Then the weekend starts with Practice 3 on Saturday at 3 p.m. ET. Each of those events should proceed without weather obstacles, according to FOX weather. Sunday’s race could be a different story.
