Today's briefing

Las Vegas is warming up nicely this morning at 26 degrees, though it feels a touch cooler at 23 degrees with just a gentle 4 kilometre-per-hour breeze keeping things comfortable for now. Today's going to be a scorcher, with the mercury climbing to a hot 40 degrees and absolutely no rain expected, though you'll want to keep an eye on that very high UV index of 9. Make sure you've got lightweight, loose-fitting clothes sorted and don't forget the sunscreen and hat, because that UV is no joke out here. The weekend looks fairly consistent with Saturday hitting 40 degrees and staying dry, whilst Sunday stays equally warm at 40 degrees with just a slight 6 percent chance of a spot of rain.

Las Vegas weather, explained

How to read the Las Vegas forecast

A good forecast is really three views at once. The current panel tells you what it feels like outside right now, which is what matters before you head out the door. The hourly strip is for planning the next part of your day: when the rain band arrives, when the wind picks up, when it is warm enough to walk. The seven-day outlook is for the week ahead, and it is most reliable in the first three or four days. Read it from the top down and you will almost always have what you need for Las Vegas.

What the UV index actually means

The UV index rates the strength of the sun's ultraviolet radiation on a simple scale. Below 3 is low and you can be outside safely without protection. From 3 to 7 is moderate to high, the point at which sunburn becomes likely within an hour, so a hat and sunscreen earn their keep. Above 8 is very high to extreme, and skin can burn in minutes around the middle of the day. The index peaks at solar noon, not at the hottest part of the afternoon, so the safest habit is to check the number rather than judge by the temperature.

Why the overnight low matters as much as the high

Daytime maximums get the headlines, but the overnight minimum shapes how the day actually feels. A cold night means a slow, crisp start and, on clear evenings, the chance of fog or frost before dawn. A mild night means the warmth carries over and the morning is comfortable from the outset. Clear skies let heat escape and push the low down; cloud cover traps it and keeps the night warmer. That is why two days with the same maximum can feel completely different depending on the night that came before.
