8月的菲尼克斯旅人笔记
来自附近斯科茨代爾的笔记(相距 18 公里)
菲尼克斯还没有自己在8月的笔记——下面这些是关于斯科茨代爾的,离得够近,季节相同。
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.

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.
April is the month regulars here call their favourite: cool mornings, warm days, and the spring-training crowd gone home, because that fills March and takes the hotel rates with it. Their figures are the mid-eighties by day and mid-fifties at night; ours run a little warmer at 31.4C over 17C, and the number that matters more is 21 percent humidity with a dew point of minus 1.6C - which is why a 31.4C afternoon reads as 29C and why the mornings are genuinely cold. Their day plan follows from it: hike at dawn, pool in the afternoon. Rain is 2.8mm in the whole month. The record: 12 hours of sun, a 15.9 kph wind and AQI 53.
Regulars call February here perfect hiking weather and give highs in the low seventies with overnight lows in the upper forties. Our row agrees almost exactly: 22C by day and 9.3C by night, with 19.2mm of rain across 2.9 days and 9.5 hours of sun. The gap between those two figures is the point - nearly thirteen degrees, on 44 percent humidity and a dew point below zero - so a trail that is pleasant at eight in the morning is cold, and the same trail at two is warm. The other reason to prefer February is the calendar: baseball spring training fills the valley through March, so this is the same weather with fewer people in it. The record: a 13.5 kph wind and AQI 50.
November is the month Phoenix becomes walkable again, and the forum's advice is nonetheless to hike early or late. Even in November the midday sun is hot enough to matter - some days still reach 80F - and the trails people name are up mountains, Camelback, South Mountain and the Phoenix Mountain Preserve, where there is no shade to speak of. North Mountain is the one they hand to anybody wanting easy or mid-range. The other half of the month is the evening: early November is very pleasant but a jacket comes out after dark, and the later in the month you go the chillier it gets. Our row's 26C day against a 12.9C night is that spread. The record: 1.4 precipitation days carrying 10.4mm, humidity 37 percent and 9.2 hours of sun.

Heat-day trail closures
5月1日 – 9月30日 · 通常有停业On excessive heat warning days the city shuts the Camelback, Piestewa and South Mountain trails from eleven to five and fines people who go anyway. Expect several dozen such days a summer. 来源 ↗

North American monsoon
6月15日 – 9月30日有风险Storms build over the mountains most afternoons from mid-June and break over the valley with an hour of wind and rain. It takes the edge off the heat and puts the humidity up instead.

Haboobs
7月1日 – 9月10日 · 通常沙尘季有停业Thunderstorm outflows lift a wall of dust hundreds of metres high across the valley in minutes, grounding flights and dropping visibility to nothing. A few a summer, mostly in July and August. 来源 ↗
