Texas weather can throw you some serious curveballs if you’re not prepared. From scorching heat waves to flash floods and tornadoes, the Lone Star State experiences it all.
Whether you’re heading to humid Houston or the dry deserts of El Paso, understanding local weather patterns could make or break your Texas adventure.
1. Prepare For Heat, Even In Spring And Fall
Summer isn’t the only scorching season in Texas. Even March and October can deliver temperatures above 90°F, especially in places like San Antonio and the Rio Grande Valley.
Lightweight, breathable clothing becomes your best friend. Pack moisture-wicking fabrics and light colors that reflect rather than absorb the sun’s intensity. Sunscreen with at least SPF 50 is non-negotiable, reapply every two hours.
Early mornings and evenings offer relief, so schedule outdoor activities accordingly. The midday sun between 11am-3pm can be particularly brutal, even during “cooler” seasons.
2. Watch For Severe Storms
Those gorgeous blue Texas skies can transform into menacing storm fronts within hours. The eastern half of Texas sits in ‘Tornado Alley,’ making spring particularly volatile with dramatic weather shifts.
Storm-tracking apps like RadarScope provide real-time updates that national weather services might miss. The purple-red radar blotches? Those indicate potential hail; something your rental car company won’t appreciate.
Hotel staff can offer valuable local insights about storm patterns. Many Texans have weather wisdom passed down through generations about which cloud formations spell trouble in their specific region.
3. Pack Layers For North Texas
Morning frost giving way to afternoon sunshine isn’t uncommon in Dallas-Fort Worth and the Panhandle. Temperature swings of 30 degrees within a single day happen regularly, especially during fall and spring.
The secret? Layering with pieces you can easily add or remove. A light jacket, thin sweater, and t-shirt combination works wonders. Scarves serve double duty, warmth in the morning, sun protection in the afternoon.
Northern Texas winds can make temperatures feel significantly colder than what’s on the forecast. The “feels like” temperature matters more than the actual reading when deciding what to wear each day.
4. Respect The Wind In West Texas
Amarillo locals joke that if you don’t like the weather, wait five minutes; and the wind is usually behind those rapid changes. Gusts regularly exceed 40mph across the plains, kicking up dust devils that reduce visibility without warning.
Sensitive electronics deserve extra protection in this environment. Dust particles find their way into camera lenses and laptop keyboards with remarkable efficiency. Bring protective cases or at minimum, ziplock bags as emergency covers.
High-profile vehicles like RVs and moving trucks require extra caution on west Texas highways. Strong crosswinds on long, straight stretches of road can push vehicles into other lanes unexpectedly.
5. Flooding Happens Fast
Blue skies overhead don’t guarantee safe passage in Central Texas, especially along the Hill Country. Flash floods develop with terrifying speed, sometimes from storms miles away that you never even witnessed.
Six inches of rushing water can knock adults off their feet; twelve inches will float most vehicles. The limestone terrain throughout Central Texas doesn’t absorb rainfall well, creating instant rivers where dry creek beds stood moments before.
When rain begins, move to higher ground immediately. Memorize the local emergency number (usually 911) and download the FEMA app for flood alerts specific to your location. Never, ever drive through water-covered roads.
6. Hydration Is Non-Negotiable
Your body loses moisture in Texas long before you feel thirsty. The combination of low humidity in western regions and high heat throughout the state creates perfect conditions for sneaky dehydration.
Smart travelers carry insulated water bottles that keep liquids cool for hours. Aim for at least 16oz every two hours while sightseeing, more if you’re active outdoors. Electrolyte packets added to water help replace minerals lost through sweating.
Monitor your urine color as an easy hydration check. Pale yellow means you’re doing well; anything darker signals it’s time to drink more. Even mild dehydration can trigger headaches and fatigue that ruin vacation plans.
7. Check Coastal Conditions
Gulf Coast beaches offer stunning getaways, but they come with unique weather challenges. Hurricane season officially runs June through November, though August and September typically see the most activity.
Beach flags aren’t just decorative; they’re crucial safety indicators. Green means calm conditions, yellow suggests caution, red indicates high hazard, and purple warns of dangerous marine life. Double red flags mean the water is closed to public swimming.
Rip currents claim more lives than hurricanes along Texas shores. If caught in one, swim parallel to the shore until you’re free from the current, then angle back toward land. Fighting directly against the flow leads to exhaustion.
8. Know The Microclimates
Texas spans multiple climate zones across its vast territory. El Paso’s desert might be experiencing bone-dry 95°F heat while Houston simultaneously deals with tropical 85°F humidity that makes it feel like 100°F.
The Hill Country around Austin and Fredericksburg creates its own weather patterns. Evening temperatures often drop 20+ degrees from daytime highs due to elevation changes, bringing welcome relief after scorching afternoons.
Research historical weather data for your specific destinations rather than relying on general “Texas weather” forecasts. The state’s size means conditions in one region rarely reflect what’s happening elsewhere; pack accordingly for each stop on your itinerary.
9. Protect Against Sun Glare
Texas sunshine delivers an intensity that catches many visitors off guard. The flat, wide-open landscapes of many regions mean nothing blocks the sun’s direct assault on your eyes and skin. Quality polarized sunglasses aren’t just for comfort, they’re safety equipment, especially when driving. The glare off highways can cause momentary blindness, particularly dangerous on remote roads where speed limits can reach 80 or even 85 mph on specific stretches, like the SH 130 toll road between Austin and Seguin. Morning and evening drives present the worst glare challenges. The low-angle sun creates blinding conditions that regular sunglasses can’t fully handle.
10. Use Local Weather Resources
National weather apps often miss critical regional details in a state as vast as Texas. Local meteorologists understand nuances like when the sea breeze typically pushes inland or how certain hill formations affect storm development.
Television stations in major Texas cities offer free weather apps with superior radar coverage and alerts tailored to smaller geographic areas. KXAN in Austin, KHOU in Houston, and WFAA in Dallas provide particularly detailed forecasts.
Follow county-specific emergency management offices on social media for the most immediate alerts. These accounts often post weather warnings before they reach broader channels, giving you precious extra minutes to prepare or change plans.
