8月的拉斯维加斯旅人笔记
拉斯维加斯的其他月份
Regulars are consistent that the dry heat here is a real, meaningfully different experience than a humid climate at the same temperature - sauna heat rather than steam room heat, with sweat evaporating fast enough that feeling sticky isn't really a problem. Our row backs the dry read directly, 32.1C reading as a real 29C, over 19.5C nights, with rain almost entirely absent, 4.5mm across under a day, and humidity down to a desert-dry 21 percent. Regulars are specific that the first two weeks tend to run more comfortable, with the back half of the month often pushing toward 100 Fahrenheit and nights that stay warmer too as the month wears on. The record: 12.9 hours of sun, a 16.7 kph wind and AQI 64.
February is the month regulars warn is not a pool holiday. Most resort pools are closed for the season; a handful of the big properties keep a heated one open, and if yours is shut you are usually told at check-in which neighbour will have you. Outdoor dining and club terraces are largely closed too, and walking the strip after dark is genuinely unpleasant. Our row shows why: 18C by day reads as 14C, and 6.8C at night reads as 3C, on 40 percent humidity and a dew point of minus 4.9C - desert air keeps nothing after sunset. Rain is 14mm across 1.9 days. The record: 9.4 hours of sun, a 14.4 kph wind and AQI 43.
Regulars describe November here as sunny days and cool, often windy nights, and the numbers are starker than that sounds. Our row gives 20.9C by day but a felt 18C, and 9.1C at night that feels like 5C - a desert November at 34 percent humidity with a dew point of minus 4.1C loses its heat the moment the sun goes. Their verdict on the pools is worth having before booking: mid-November is very iffy even where the water is heated, and several resorts keep only one pool open. Rain is 6.7mm in the month. Take a light layer for the day and a proper coat for the evening. The record: 8.9 hours of sun, a 12.6 kph wind and AQI 38.
March is the month the Las Vegas forum calls the most erratic of the year - 80s one year, struggling out of the 50s the next - with an average high near 70F, an average low near 45F, and a reputation as one of the windier, cloudier months. Wind and cloud together make it feel a good deal cooler than the number suggests. The practical question is the pools: many open by mid-March for spring break, and the realistic expectation for the end of the month is a mix of pool days and days too cool for it. Pack layers and keep an indoor plan. The record: 21.8C days that feel like 18C, 10.3C nights, 2 precipitation days, humidity 36 percent and 10.5 hours of sun.
