Why was metro Phoenix extreme heat warning extended?<\/p>\n
\u201cThe main reason we extended the extreme heat warning is because we\u2019re going to continue to see areas of major heat risk into early next week,\u201d Gabriel Lojero of the NWS in Phoenix told KTAR News 92.3 FM on Friday afternoon.<\/p>\n
The Phoenix weather forecast calls for high temperatures of 110-113 degrees in the coming days, along with a slight increase in humidity that will make conditions worse. The normal high for this time of year is 105 degrees.<\/p>\n
\u201cOur overnight low temperatures are still going to remain pretty elevated in the upper 80s to around 90 degrees,\u201d Lojero said. \u201cSo as a result, there\u2019s not going to be as much of overnight relief for the body to recuperate.\u201d<\/p>\n
While the conditions are hot enough to extend the extreme heat warning, it\u2019s actually a break after two days of record-setting heat.<\/p>\n
On Thursday, it reached 118 degrees<\/a> at Phoenix Sky Harbor International Airport, which the NWS uses for the city\u2019s official readings. It was the hottest August day ever recorded in Phoenix and broke a 120-year-old heat record for Aug. 7. It also tied July 9 for the hottest day of 2025.<\/p>\n
A day earlier, Phoenix reached 116 degrees<\/a> to break a 30-year-old record for the date.<\/p>\n
\u201cThe good news is that we\u2019re not expecting temperatures of those extremes because we\u2019re not seeing the record high pressure strength that we saw the last couple of days,\u201d Lojero said.<\/p>\n
How to stay safe during extreme heat warnings<\/p>\n
Due to the dangerous conditions, the following Phoenix hiking trails\u00a0are restricted<\/a>\u00a0from 8 a.m. to 5 p.m. on extreme heat warning days:<\/p>\n
\n
- Camelback Mountain: Echo Canyon Trail and Cholla trail.<\/li>\n
- Phoenix Mountains Preserve: Piestewa Peak Summit Trail and associated trails.<\/li>\n
- South Mountain Park and Preserve: Holbert Trail, Mormon Trail, Hau\u2019Pal Loop Trail and access to the National Trail from the Pima Canyon Trailhead.<\/li>\n<\/ul>\n
\u201cGiven that we extended the extreme heat warning through the weekend into early next week, it\u2019s a good reminder that people need to take all the necessary heat precautions: Try to limit your time spent outdoors, drink lots of water, keep yourself hydrated,\u201d Lojero said.<\/p>\n
Another tip is to wear light, loose-fitting clothing. <\/p>\n
\u201cIf you have to be outside for an extended period of time, try to take frequent breaks in the shade,\u201d Lojero said.<\/p>\n
