Rain chances will increase later this week and expand into the lower deserts. The best chances will fall on Thursday and Friday. Moisture levels will still be fairly limited, so rainfall amounts should be on the light side for most locations. #azwx<\/a> #cawx<\/a> pic.twitter.com\/59P6knhE90<\/a><\/p>\n \u2014 NWS Phoenix (@NWSPhoenix) August 12, 2025<\/a><\/p>\n<\/blockquote>\n When was the last time it rained in Phoenix?<\/p>\n It hasn\u2019t rained at Phoenix Sky Harbor International Airport, which the NWS uses for the city\u2019s official readings, since 0.16 inches fell on July 2. That also was Phoenix\u2019s only measurable rainfall since the official start of the monsoon season on June 15.<\/p>\n \u201cSo far this monsoon, it\u2019s been fairly dry across south-central Arizona. \u2026 We still have a month-and-a-half to go here, so we still have time to make up the difference,\u201d O\u2019Malley said.<\/p>\n Arizona\u2019s monsoon season runs through Sept. 30 each year.<\/p>\n In addition to bringing moisture to the Valley, the weather system is expected to drop daily highs to the normal range of 105 degrees for this time of year \u2013 and possibly lower.<\/p>\n \u201cWe are looking for some cooler weather entering the Phoenix metro later this week,\u201d O\u2019Malley said. \u201cBy the weekend, high temperatures in the metro only will be between about 100 and 105 degrees.\u201d<\/p>\n Why was extreme heat warning extended in Phoenix?<\/p>\n But first, the Valley will have at least two more days under an extreme heat warning.<\/p>\n The advisory originally went into effect Aug. 1 and has been extended multiple times. Late last week, the NWS extended it<\/a> through 8 p.m. Tuesday. But another day was added<\/a> due to persistent extreme heat.<\/p>\n The Extreme Heat Warning for portions of south-central and southwest AZ and southeast CA has been extended through Wednesday evening. Expect highs temperatures mostly between 109-113\u00b0 for today and Wednesday. Near normal temperatures are forecast by Friday. #azwx<\/a> #cawx<\/a> pic.twitter.com\/lWtGLD56My<\/a><\/p>\n \u2014 NWS Phoenix (@NWSPhoenix) August 12, 2025<\/a><\/p>\n<\/blockquote>\n \u201cWe\u2019re looking at temperatures in the Phoenix metro area around 110 over the next couple of days.

Furthermore, Thursday was the hottest August day ever recorded<\/a> in the city with a high of 118 degrees.<\/p>\n Due to the dangerous conditions, the following Phoenix hiking trails are restricted<\/a>\u00a0from 8 a.m. to 5 p.m. on extreme heat warning days:<\/p>\n KTAR News 92.3 FM\u2019s Kellen Shover contributed to this report.<\/p>\n Follow @kstonezone<\/a><\/p>\n We want to hear from you.<\/p>\n Have a story idea or tip?
