You might forgive those who swallowed hard when the power went out late Thursday afternoon.

On a day when the temperature reached 118 degrees, according to the National Weather Service in Phoenix, the prospect of no air conditioning for any length of time was disconcerting.

Luckily, the outage was relatively short-lived – about 30 minutes – for at least some residents. But others were apparently without electricity for nearly three-and-a-half hours. One Senita resident posted on Facebook that her power only came back around 8 p.m.

According to a map on the Electrical District No. 3 web site, the outage affected about 1,300 customers in its North Central Region, an area bounded on the east by North White and Parker Road, on the north by the city boundary, on the west by the Ak-Chin Indian Community and on the south by West Peters and Nall Road. It was unclear whether that number included some who had their power back relatively soon.

Electrical District No. 3 did not immediately respond to InMaricopa for a comment on the outage.

According to posts on Facebook, the outage hit homes in at least some parts of Glennwilde, Senita 1 and 2, and the Villages. Some reported their electricity went out, came back on briefly and then went out again. Businesses in the Maricopa Business Center at the western end of Honeycutt Road also lost power – for about 30 minutes.

Thursday’s temperature, recorded at the Phoenix Sky Harbor Airport, broke the record for the daily high for the date, 114 degrees set in 2015, according to the National Weather Service, which noted there have only been 18 other days in Phoenix’s period of record to reach 118 degrees or greater. Temperatures should reach a high of 115 degrees or greater through Sunday, forecasters said.
