Palm Springs weather in July

Joshua Tree-forum threads on a summer visit call July genuinely hot but note the park runs a real ten degrees Fahrenheit cooler than nearby Palm Springs, the elevation doing real work. Regulars describe day-to-day swings as considerable, some days sitting in the high eighties with a breeze while others climb well past a hundred and ten. Posters recommend hiking only in the early morning before the real heat builds, afternoons better spent somewhere with shade or air conditioning. Regulars call carrying far more water than feels necessary standing advice, dehydration a genuine risk even on a short walk. Posters describe the desert as still worth the visit despite the heat, sunrise and sunset both considerably more comfortable windows for exploring. Regulars recommend checking a real-time forecast rather than a general seasonal average before any longer outing. The record: 39.1C days feeling like 39C, 24.5C nights, a scant 0.5 days of measurable precipitation and 26 percent humidity.

Forum posters describe May in Palm Springs as genuinely hot, with highs commonly in the upper 90sF especially later in the month - one May visitor reported highs in the upper 90s to low 100sF most days, along with warm overnight temperatures and occasional poor air quality from blowing dust and sand. Posters consistently recommend early May specifically over late May for anyone prioritizing pool time without triple-digit heat, describing that window as warm enough to swim in an unheated pool while still falling short of the true 100+F heat typical from June through September. Posters consistently flag May, alongside late October, as a genuine shoulder-season sweet spot for avoiding peak winter rates while still getting comfortable outdoor conditions, at least early in the month. Posters generally recommend planning outdoor time for morning or evening once temperatures climb later in May.

November is the desert at its best, and the forum's own window is roughly 15 October to 1 December: days around 24°C, nights dropping to about 12. Two things they raise that the temperature cannot. First, light — the sun goes behind the mountains close to 4pm and it is dark by about 5 by mid-month, which shortens an afternoon far more than the date suggests. Second, timing inside the month: the end of November fills up with snowbirds arriving and Thanksgiving. Pools swim fine on a sunny day if heated; unheated ones really do not. Rain is rare, though storms do pass through.
