Heatwave grips Florida, Texas, California with temperatures over 100°F

Millions across the southern and western United States are preparing for a severe heatwave expected to dominate the weather over the next several days. The intense heat, with temperatures soaring above 100°F (38°C) in many areas, will coincide with the ongoing FIFA World Cup 2026 matches hosted in the U.S.

South Florida faces particularly extreme conditions. Miami is anticipating heat index values between 103°F and 106°F (39°C to 41°C), despite daytime highs of 90°F to 95°F (32°C to 35°C). The National Weather Service (NWS) in Miami has issued warnings, indicating a 50% to 70% chance of elevated health risks, particularly for the elderly, young children, and individuals with pre-existing medical conditions. While a high-pressure system may bring more stable weather, isolated afternoon thunderstorms are still possible, mainly in inland and southwestern parts of the state.

In the Tampa Bay area, the NWS expects heat to be a constant throughout the week. Daily heat index values are projected to exceed 105°F (41°C), with actual temperatures ranging from 88°F to 98°F (31°C to 37°C), depending on proximity to the coast. Rain chances and storms are more likely in inland areas and south of Interstate 4.

Texas is also bracing for dangerous heat. The NWS forecasts extreme temperatures, especially in the western and southwestern regions, where thermometers are expected to surpass 100°F (38°C). The Midland/Odessa NWS office specifically warned of dangerous heat on Monday, with widespread highs between 100°F and 110°F (38°C to 43°C). Authorities are urging residents to take precautions, including drinking plenty of water and seeking shade to prevent heat exhaustion and heatstroke. Isolated storms may also occur in some parts of Texas during the afternoon and evening.
