Las Vegas, NV – A stretch of warm, sunny afternoons across the Las Vegas Valley will give way to cooler temperatures just in time for Halloween, with the National Weather Service projecting a high near 70 degrees Saturday, Oct. 31. Temperatures are expected to remain near 79 degrees through the middle of the week before slipping into the mid 70s Friday. A slight chance of showers also enters the forecast Friday night and Saturday, potentially affecting outdoor celebrations across the metropolitan area.
According to the National Weather Service in Las Vegas, Wednesday, Oct. 28, should bring mostly sunny skies and a high near 79 degrees, followed by mostly cloudy conditions and a low around 61 degrees Wednesday night. Thursday continues the mild pattern with partly sunny skies and another high near 79 degrees. The more noticeable temperature change develops toward the weekend, when afternoon highs fall approximately 9 degrees between Thursday and Saturday.
Cooler Temperatures Arrive for Halloween Weekend The transition begins Friday, Oct. 30, as temperatures drop to approximately 75 degrees under partly sunny skies. Friday night brings partly cloudy conditions, a low near 59 degrees and a slight chance of showers. The National Weather Service has not provided a specific precipitation percentage or rainfall accumulation estimate for this period.
Saturday, Oct. 31, is expected to be mostly sunny, with temperatures reaching approximately 70 degrees and a slight chance of showers. Although rain remains possible, the forecast does not indicate widespread precipitation or a significant storm system affecting Las Vegas. The cooler afternoon temperatures could provide more comfortable conditions for daytime Halloween activities compared with the warmer weather earlier in the week.
The projected cooldown is gradual rather than abrupt. Thursday's expected high of 79 degrees falls to 75 Friday and 70 Saturday, representing a 9 degree decrease over two days. The forecast does not support freezing temperatures, severe thunderstorms or hazardous winter weather in the Las Vegas Valley.
Warm and Sunny Conditions Continue Through Midweek Before the weekend transition, residents can expect several afternoons featuring sunshine and temperatures near 80 degrees. Monday, Oct. 26, begins partly sunny before gradually becoming sunny, with a high around 78 degrees. East southeast winds could reach 5 to 7 mph during the afternoon.
Tuesday brings sunny skies and a high near 79 degrees, followed by mostly clear conditions and a low around 60 degrees. Wednesday continues the pattern with mostly sunny skies and another high near 79 degrees. These conditions should generally favor outdoor activities and routine travel across the metropolitan area.
Motorists using Interstate 15, U.S. Highway 95 and Interstate 215 should encounter generally favorable weather through much of the workweek. However, any showers developing Friday night or Saturday could create isolated wet pavement. No road closures, weather related traffic disruptions or flooding threats are established by the supplied local forecast.
What Residents Should Watch Before Saturday The primary forecast question heading into Halloween is whether the slight shower chance becomes more organized or remains limited. The National Weather Service outlook does not specify the timing or coverage of possible rainfall, making it too early to determine whether evening trick or treating activities will be affected.
Residents planning outdoor gatherings should monitor updated forecasts later in the week, particularly for Saturday's temperatures and precipitation chances. While cooler weather appears likely, the forecast currently favors mostly sunny skies Saturday rather than persistent rainfall.
