What to watch for on this route
In the planner, TripCaptain highlights forecast weather risks between Austin, TX and Dallas, TX and summarizes the analysis with a Hazard Score™ from 0 to 100. A higher score indicates lower forecast risk, without guaranteeing road conditions.
- Severe Thunderstorm: I-35 runs through the heart of Texas hail country — spring supercells bring giant hail, damaging winds, and tornado risk near Waco and Temple.
- Flash Flooding: Central Texas is one of the most flash-flood-prone regions in the US; intense rain can put water over low I-35 frontage roads in minutes.
- Extreme Heat: Summer temperatures regularly top 38°C (100°F), stressing tires on hot pavement and raising the risk of engine overheating in stop-and-go traffic.
When to go, season by season
- Spring (Mar–May): Peak severe-storm season — giant hail, tornadoes, and flash flooding are all possible. Check radar before driving; this is the highest-risk season.
- Summer (Jun–Aug): Extreme heat. Check tire pressure, carry water, and avoid long midday stops. Otherwise dry and predictable driving.
- Fall (Sep–Nov): The best driving season — warm, mostly dry, and calm. A secondary minor storm peak can occur in October.
- Winter (Dec–Feb): Mild most days, but rare ice storms can glaze I-35 and shut the corridor — the February 2021 freeze is the cautionary example.
