The study<\/a>, created by the real estate information firm Cotality, predicted the average number of days counties will spend above three temperature thresholds in 2050 \u2014 days above 95 degrees, days above 110 and days above 120. Yuma County leads the nation in the first metric, with a forecasted 171 days above 95 degrees. Imperial County in California is second with 162 days at 95-plus. Rounding out the top five are La Paz County (155.9), Maricopa County (155.3) and Pinal County (146.9) \u2014 all in Arizona.<\/p>\n Cotality\u2019s head of research and development, Anand Srinivasan, said the company used counties as a foundation for the study because they use lots of data inputs but are not too large to draw conclusions about the effects of heat.<\/p>\n The rankings were the same for the number of days with temperatures greater than 110 degrees, which is closer to what Valley residents might consider \u201cextreme heat.\u201d<\/a> Yuma is predicted to see 65 such days of 110-degree heat \u2014 a 33% increase from today, according to the analysis. In populous Maricopa County, the annual number of 110-plus degree days is expected to increase by 39% to 46 days every year. While that projected figure is higher than the annual average in Phoenix, it\u2019s less than recent record-setting years<\/a> in 2024 (70 days) and 2023 (55).<\/p>\n The study raises an obvious question: If Arizona is going to be that hot, will anyone want to live here?<\/p>\n Even as temperatures and extreme heat days have been climbing in recent years, the Valley\u2019s housing market has seen a boom. Between 2016 and 2020, about 100,000 people moved to Arizona, the study said, with about 44% of them settling in Maricopa County, which is home to Phoenix.<\/p>\n \u201cThe fact that Phoenix, on a comparable basis, was more affordable to other large cities may have been a draw. But it brings about a different set of risks,\u201d Srinivasan told Phoenix New Times in a phone interview. \u201cWhat is the straw that breaks the camel\u2019s back proverbially, if there is one? It\u2019s nearly impossible to tell.\u201d<\/p>\n He mentioned Florida\u2019s insurance crisis<\/a>, which resulted in more migration out of Florida as insurance companies denied coverage for properties at substantial risk to climate change and extreme weather, as an example of such a challenge.\u00a0<\/p>\n As one might expect, a concern for the desert is water. In the next 25 years, water scarcity is expected to be a key issue for Arizona, which will lose 18% of its Colorado River water allocation<\/a> in 2026 thanks to a drought the likes of which the Southwest hasn\u2019t seen in 1,200 years<\/a>. Arizona is also depleting its groundwater at alarming rates<\/a>, and water scarcity has already limited homebuilding.<\/p>\n \u201cIf temperatures increase too drastically, it will dull the attraction of sunshine and low taxes that brought people to Arizona in the first place,\u201d Dr. Howard Botts, chief scientist at Cotality, said in a statement. \u201cBut adaptation is possible. With forward looking models and an understanding of how hot is too hot for certain construction choices or locations, we can create resilient communities across the American Southwest.\u201d<\/p>\n Still, Cotality noted that even lesser-known parts of Arizona, like Yuma, are experiencing real estate growth. In Yuma, the company estimated that by July 2026, home prices will increase by about 4%, outpacing national price growth.<\/p>\n Some are still feeling bullish. About half of Phoenix\u2019s housing inventory was purchased by investors in the first half of 2026, making the Valley the fourth-biggest market for property investors. Those buyers were mainly small-time landlords with fewer than 10 properties, while institutional investment decreased by 12%.<\/p>\n All signs point to our already-sizzling climate getting hotter, but it\u2019s unclear whether those changes will spell doom for Arizona\u2019s recent status as a popular living destination. While Arizona is attracting new residents, Cotality noted there\u2019s already a trend of Arizonans leaving for cooler, cheaper states like Colorado or Texas. \u201cThese nearby states boast strong job markets, an array of natural resources, and cooler climes filled with plenty of sunshine,\u201d the study said.<\/p>\n Time will tell if droves decide they can\u2019t take the heat. But right now, so long as the water\u2019s running and the lights are on, it seems to be business as usual in the desert.<\/p>\n","protected":false},"excerpt":{"rendered":"Here\u2019s something to think about \u2014 in just a few months, we\u2019ll be closer to the year 2050…\n","protected":false},"author":3,"featured_media":284531,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5131],"tags":[5229,5643,1587,285,1589,4329,67,586,132,5230,68,2969],"class_list":{"0":"post-284530","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-phoenix","8":"tag-america","9":"tag-arizona","10":"tag-az","11":"tag-climate-change","12":"tag-phoenix","13":"tag-real-estate","14":"tag-united-states","15":"tag-united-states-of-america","16":"tag-unitedstates","17":"tag-unitedstatesofamerica","18":"tag-us","19":"tag-usa"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/115334287599816455","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/284530","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=284530"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/284530\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/284531"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=284530"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=284530"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=284530"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"a](\"https:\/\/www.europesays.com\/us\/wp-content\/uploads\/2025\/10\/Cotality-Hottest-Counties-Graph.png\")
