PHOENIX — Beware to those planning to spend the Labor Day weekend outside in metro Phoenix: It’s going to be hot.

The Valley will be under an excessive heat warning from 10 a.m. Saturday until 8 p.m. Monday, according to the National Weather Service.

Temperatures are expected to hit between 106 and 108 degrees daily through Tuesday.

“The heat’s not going away. This is part of a prolonged event,” Sean Benedict, a meteorologist with NWS Phoenix, told KTAR News 92.3 FM on Wednesday. “The temperatures will be a few degrees above normal through at least Labor Day.”

The forecast calls for overnight lows in the mid-80s through the weekend.

After a stretch of relatively moderate temperatures, this weekend’s excessive heat warning will be the second in less than a week.

Phoenix hit 110 degrees on Tuesday, the only time in the August the mark was hit.

Excessive heat warnings trigger a daytime shutdown of select hiking trails in Phoenix.

Camelback Mountain’s Echo Canyon and Cholla trails and all Piestewa Peak trails will be off limits Saturday-Monday from 11 a.m. to 5 p.m., per city policy.

Regional planning agency Maricopa Association of Governments has prepared a list of heat relief sites that operate during excessive heat warnings.
