Phoenix wakes up muggy and hot on Tuesday, July 14, 2026, with partly cloudy skies and temperatures already sitting in the low 80s this morning. Highs are expected to climb near 106°F this afternoon, and humid evenings will bring little overnight relief as lows settle in the upper 80s to low 90s. If you have plans outside, push activity to early morning or after sunset and carry water.
Extreme Heat Warning In Effect
The National Weather Service has issued an Extreme Heat Warning for the lower deserts from 10 a.m. Tuesday, July 14 through 8 p.m. Thursday, July 16, with heat index values forecast to reach around 111°F. Overnight minimums staying in the 80s are a major concern, since bodies have little chance to recover between hot days and hot nights. Residents are urged to monitor heat illness symptoms and check on neighbors who may be vulnerable, according to the National Weather Service Phoenix.
What To Expect Today And Tonight
Sunny skies and light southeast winds will push temperatures into the mid 100s this afternoon, with only a slight chance of showers or thunderstorms late Tuesday night. Most of the valley should stay dry through the evening, and any thunderstorms that do form are expected to be widely scattered and brief. Winds will remain light at 0 to 5 mph through the day, so heat and humidity, not wind, will be the primary concerns.
Heat Relief And Cooling Centers
The City of Phoenix is operating a network of cooling centers, hydration stations and respite sites. If you need a cool place or help getting there, call 2-1-1 for locations and transportation options. For the official list of sites and hours, see the City of Phoenix cooling centers. For background on the valley’s recent heat trends, check earlier reporting.
Late-Week Storm Risk
A disturbance arriving from the east later this week is expected to increase shower and thunderstorm coverage on Thursday and Friday, with the highest odds of widespread storms and localized heavy rainfall on Thursday. Where storms train or stall, brief heavy downpours could produce localized flash flooding. Forecasters say flash flooding is the main thunderstorm hazard, so avoid low-lying washes and do not drive through flooded roadways. Keep an eye on the forecast and alerts from the National Weather Service Phoenix for updates.
Practical Tips
Limit exertion during the hottest hours, roughly 11 a.m. to 6 p.m., drink fluids often, and seek air-conditioned spaces if you feel faint or confused. Employers and outdoor crews should schedule frequent breaks and ensure access to shade and water. If roads are flooded after storms, remember: turn around, do not drown. Check in on older neighbors, secure pets, and shift errands to cooler hours when possible.
