Nevada Climate – June 2026 Update

Top 5 Cities: Las Vegas, Henderson, Reno, North Las Vegas, and Sparks

This month in numbers

Nevada experienced its 7th warmest June on record, with an average temperature of 20.44°C, marking an anomaly of +2.4°C compared to the 1961–1990 baseline. The three-month period from April to June 2026 also ranked as the 7th warmest on record, with an average temperature of 14.76°C, an anomaly of +1.9°C. Globally, June 2026 was the 3rd warmest June on record for land temperatures, with an anomaly of +1°C, while the April–June period ranked as the 2nd warmest globally, also with an anomaly of +1°C.

What changed

Nevada's consistently warm temperatures this spring and early summer stand in contrast to a national picture that has also been warmer than average, but to a lesser degree. The state's 1-month anomaly of +2.44°C made it the warmest in its NOAA West US climate region this month. The ongoing warmth follows 2025, which was Nevada's warmest year on record. The state is currently experiencing a long-term warming trend of +1.23°C compared to the 1961–1990 baseline.

What’s driving change?

The persistent warmth in Nevada is largely driven by the long-term warming trend, a background climate signal that is increasingly influencing regional temperatures. This is compounded by the current weak El Niño, which is forecast to strengthen and persist through the rest of the year, potentially bringing warmer conditions to the region. El Niño typically leads to a wetter winter for the Southwest, which can initially reduce fire risk, but also spurs the growth of grasses that can later dry out and increase wildfire danger. Nevada has seen an unusual concentration of wildfire activity recently, with four wildfire events between late June and early July representing 100% of the past 12 months' total, alongside a significant flood event in June. This includes flash flooding and mudslides in northern Nevada in June, impacting nearly 100 homes and prompting emergency shelter-in-place orders in Hidden Valley.

Looking ahead

The strengthening El Niño is expected to bring warmer and drier conditions to northern and western areas of the Great Basin later in the summer, with pulses of monsoon moisture potentially moving into the eastern Great Basin from mid- to late-July.

Shifting Seasons

Warm / cold seasonsKöppen BSk · Arid

How spring and autumn have shifted in Nevada. Spring is defined as the date monthly temperatures first rise above the long-term annual mean (9.7°C, from 19501979); autumn is the date they fall back below it. Temperature swings 23.3°C peak-to-peak across the year - a classic four-seasons rhythm.
