Regulars describe typically dry, sunny days in the 60s-70s Fahrenheit with genuinely chilly evenings, and note that resorts specifically run heated pools this time of year to make swimming a real option despite the season. Our row backs the mild-but-cool read, 20.5C reading as 18C over 8.5C nights feeling 5C, with rain minimal at 19mm across 2.7 days, and humidity down to a dry 52 percent. Regulars are candid that occasional cold spells can drop daytime highs into the 50s Fahrenheit with colder nights, and one long-time Scottsdale resident even reports snow showers three times in ten years around Christmas week - rare, but real. This remains genuinely one of the more popular months here, people specifically traveling in for the mild winter climate. The record: 8.2 hours of sun, an 11.6 kph wind and AQI 54.

Scottsdale-forum threads on November weather show a real split across the month: early November can still run into the 80s Fahrenheit some years, while by Thanksgiving week it's settled to around 70F by day and the 40s at night. By mid-month, posters say it's not really warm enough for serious pool time, though heated hotel pools take the edge off for anyone who still wants a swim. A sweater for morning and evening is the standing advice, and the city stays casual enough that jeans and a nice top cover dinner anywhere. Overall it's called a genuinely great month for outdoor time. The record: 25.1C days feeling like 23C, 11.4C nights, 16mm across 1.7 days, humidity a dry 38 percent and 9.2 hours of sun - warm days, a real chill once the sun's down.
Scottsdale's forum is consistent that early September still runs genuinely hot and can carry lingering monsoon humidity - daytime highs commonly in the upper 90s to around 100F+, overnight lows only dropping into the 70s. Monsoon season technically wraps up by July/August most years but occasionally drags into early September, bringing a chance of dust storms or lightning. Forum regulars said the back half of the month cools off noticeably and becomes genuinely pleasant, with pool time recommended for anyone visiting the earlier, hotter stretch.
Forum posters describe August afternoons in Scottsdale as regularly hitting 105-110F (roughly 41-43C), with early mornings still comfortable in the mid-to-high 70sF (around 24-26C) until about 9:30-10am. Posters consistently recommend scheduling any hiking or biking for sunrise or the very last light of the evening, spending midday by the pool in shade, since sitting poolside without cover in the early afternoon isn't advisable at these temperatures. Posters describe August's monsoon season as bringing storms that are typically neither all-day nor every-day events, but can be genuinely intense, including microbursts, when they do arrive. Posters do flag a real upside: nearly all major resorts run staycation-level deals in August as the off-season discount kicks in. Posters generally rate August as extremely hot but manageable with a schedule built around the coolest hours, and notably better value than in-season Scottsdale.
March in Scottsdale means spring training, and the forum's practical points are mostly about that: it is the busiest stretch of the year in the Phoenix area, hotel rates rise accordingly, and booking early matters. On weather, regulars put March roughly level with November — highs around 24°C, nights near 9 — and warn that mornings and evenings are genuinely cold: socks, a sweater, long trousers and often a jacket, though not a heavy coat. Rain is rare, under four days. If the baseball is the point, Scottsdale Stadium sits in Old Town with a trolley loop serving it.
