Summary
Pack for serious heat: Dallas, Houston, Miami and Monterrey regularly experience June-July humid heat with wet-bulb temperatures of 28°C (82.4°F) or higher, and Dallas hit dangerous heat-stress levels on about half of June and July days over the past decade. The good news: AT&T Stadium and NRG Stadium are air-conditioned. Here is what to bring city by city, and how to stay connected and hydrated.
Which host cities are hottest
Southern and Gulf venues carry the most heat risk. Houston is likely to see three-quarters of June-July afternoon hours above a 28°C wet-bulb reading, with muggy dew points in the low-to-mid 70s. The wider trend is real, too: extremely hot days have roughly tripled across repeat host cities since 1986. Northern venues like Seattle, Vancouver and Toronto stay far more comfortable.
Heat-readiness packing list
| Item | Why it matters |
|---|---|
| Refillable water bottle (empty) | Refill past security; key in humid heat |
| Light, breathable clothing + hat | Reflects sun, wicks sweat |
| High-SPF sunscreen + sunglasses | Long days in open-air seating |
| Electrolyte tablets + portable fan | Hydration and cooling in the queue |
Remember the clear-bag policy: bring an empty bottle in your clear bag and refill once inside.
Time your day around the heat
In hot cities, plan outdoor fan-festival time for mornings or evenings, ride air-conditioned transit during peak afternoon, and lean on the cool indoors of venues like Houston's NRG Stadium. Heading north for a match? Seattle and Vancouver are a welcome break.
