The brutal summer heat has returned to central Arizona, with Phoenix set to experience dangerous temperatures hitting a scorching 111°F starting Sunday. These extreme conditions are expected to last well into the week, raising serious health concerns for residents and visitors.
The National Weather Service has issued an Extreme Heat Watch for much of Maricopa County, including Phoenix, Tempe, Glendale, Scottsdale, Mesa, and Avondale, from Tuesday through Thursday.
Heat Watch and Risk of Heat-Related Illnesses
The Extreme Heat Watch will be in effect from Tuesday morning to Thursday evening. The highest risk for heat-related illnesses, such as heatstroke and dehydration, will occur between 11 a.m. and 6 p.m., when temperatures are at their peak.
For those planning to be outside during these hours, it’s crucial to take frequent breaks, hydrate, and find shade whenever possible.
During these hot conditions, children, seniors, and those with respiratory issues are most vulnerable. The Arizona Department of Environmental Quality has also issued a High Pollution Advisory for Monday, with ozone levels expected to reach unhealthy levels.
It is highly recommended to limit outdoor activities, particularly for sensitive groups, and to delay activities like yard work until the evening when the temperature cools slightly.
Upcoming Temperatures and Wind Conditions
Phoenix’s heat wave will begin on Sunday with temperatures nearing 109°F, followed by highs of 111°F on both Monday and Tuesday. The weather will remain similarly hot with only slight relief expected. Winds will be light, offering minimal respite from the scorching heat.
Nighttime temperatures will also remain high, staying in the upper 80s, making it difficult for people to cool down after the sun sets.
Although the hot winds may bring some gusts up to 20 mph on Wednesday, it won’t be enough to cool the region significantly. Thursday will still see dangerously high temperatures, with a high of 108°F expected.
People are urged to stay alert and avoid strenuous outdoor activities, particularly during the hottest hours of the day.
Cooling Centers and Tips for Staying Safe
To help residents cope with the extreme heat, cooling centers have been set up across Maricopa County. If you’re looking for a place to cool down, you can call 2-1-1 to find the nearest location. It’s important for outdoor workers, especially those on construction sites or road crews, to stay hydrated and take regular breaks in shaded or air-conditioned areas.
This level of heat is considered a Major Heat Risk, and without prompt action, it could lead to heat stroke, exhaustion, or cramps.
