Las vegas weather is turning sharply warmer this weekend in Southern Nevada, with dry conditions and high pressure staying overhead. Forecasters are calling for partly cloudy skies Saturday and mostly sunny conditions Sunday, with breezy periods at times. The bigger concern is the heat expected to ramp up starting Tuesday, when record heat is set to begin and continue through the week.
Weekend forecast: dry, unseasonably warm, and breezy at times
The immediate outlook keeps the region dry and well above the seasonal average. The average high temperature is 70°, and the forecast highs this week sit notably above that benchmark as the warm pattern holds.
For Saturday, conditions are expected to be partly cloudy with breezy stretches, with a forecast high of 89° and winds out of the northwest at 5–15 mph with gusts to 20. Saturday’s projected 89° also matches the listed record of 89°, putting the day in range of possibly tying that mark.
Sunday is expected to be mostly sunny and breezy, with a forecast high of 83° and winds from the north at 5–15 mph with gusts to 20. The record for Sunday is listed at 88°.
Las Vegas Weather shifts to record-breaking heat starting Tuesday
The forecast points to record heat beginning on Tuesday and continuing through the week, with multiple daily record values listed as likely to be surpassed. The hottest temperature on record in March is 93° (set in March 2022), and forecasters say that record will be broken during what is described as an intense heat wave.
Here is the set of forecast highs and the corresponding record highs provided for the coming days:
- Saturday: 89° (Record 89°)
- Sunday: 83° (Record 88°)
- Monday: 87° (Record 89°)
- St. Patrick’s Day: 92° (Record 91°)
- Wednesday: 96° (Record 90°)
- Thursday: 97° (Record 90°)
- Friday: 98° (Record 90°)
Tonight’s outlook is partly cloudy with a low of 61° and southwest winds at 5–10 mph.
Quick context: why the heat is building now
This stretch of dry, unseasonably warm conditions is tied to high pressure remaining overhead. With that setup holding, daytime temperatures are expected to remain well above the 70° average high for this time of year.
What’s next: watch Tuesday onward as records face a direct hit
The next key milestone arrives Tuesday, when record heat is expected to begin and persist through the week. Residents across the valley should keep close watch on day-to-day updates as the heat wave intensifies and daily record temperatures are challenged, with forecasters warning: stay safe as las vegas weather moves into potentially record-shattering territory.
