Fall starts on Saturday at 6:56 p.m. Pacific Daylight Time although our temperatures will approach 100° that afternoon. Above-average temperatures are expected through the weekend and next week, which means highs in the mid-to-upper 90s.
This time of year, temperatures begin to drop as we lose daylight and the sun angle decreases. When the sun is lower in the sky during the day, its ability to warm the Earth also declines.
The average high temperature drops from 94° in September to 81° in October, then to 66° in November. Lows at night are around 71° in September, 59° on October, and 47° in November.
The Climate Prediction Center predicts a 50% chance that Las Vegas sees warmer than average temperatures from October through November and December. They also suggest that precipitation will be close to average, if not slightly above. Fall is not as wet as winter or summer in Las Vegas, but we do see more rain this season than in the spring.
