8月のスコッツデールについての旅行者の声
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.
スコッツデールのほかの月
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.
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.
Scottsdale's forum calls February the height of the season, generally in the high 60s to 70s°F by day, though cold snaps into the 50s do happen. Regulars are consistent that nights get genuinely chilly enough for long pants and a light sweater even when the day was shorts weather, and that a cold, rainy stretch can still turn up despite the region's reputation for reliable winter sun.
