New Mexico Climate – July 2026 Update
Top 5 Cities: Albuquerque, Las Cruces, Rio Rancho, Santa Fe, and Roswell
Summary
New Mexico experienced its 2nd warmest July on record, capping a remarkably scorching three-month period that also ranked as the state's 2nd warmest May-July period since records began in 1950. Relentless heat stretched across the state while spotty monsoon storms brought localised flash flooding to western communities, offering only temporary relief from dry conditions. The heat is expected to persist through late summer before El Niño influences winter patterns.
This month in numbers
July 2026 was the 2nd warmest on record in 77 years of state data, with an average temperature of 25.06°C that stood 2.4°C above the 1961-1990 baseline. Daily maximum temperatures averaged 33.44°C (2.7°C above average), ranking as the 5th highest on record and translating to afternoon heat that frequently pushed near or above triple digits in valley communities. Rainfall was sparse at 43.94 mm, trailing the historical baseline by 15.3 mm. This hot month capped a summer season where the May-July average temperature hit 21.91°C (+2.3°C anomaly), also the 2nd warmest May-July period ever recorded, while maximum temperatures over those three months averaged 30.65°C to rank 3rd overall.
What changed
The heat in New Mexico forms part of an extraordinary long-term trend across North America. Over the past 12 months, the state's temperature anomaly of +3.16°C ranks 3rd highest globally among 232 tracked countries and regions, reflecting a striking geographic pattern where 7 of the top 10 warmest places on Earth over the last year are US states. Globally, land temperatures in July reached their 3rd highest mark on record (+1.6°C anomaly), while the May-July global average ranked 2nd highest. Within the NOAA Southwest region (US Southwest), New Mexico sat 3rd warmest for the month behind Utah and Colorado.
What’s driving change?
The primary mechanisms behind the region's elevated temperatures are and . When arid soils lack moisture to cool the surface via evaporation, solar energy directly heats the ground, intensifying hot spells. At higher elevations across the Rocky Mountains, thinner air and reduced snowpack further accelerate local heating. On a global scale, a moderate El Niño is active in the tropical Pacific with an anomaly of +0.98°C, tracked at ENSO. While El Niño teleconnections historically offer a modest 60% probability of wetter winter conditions across the Southwest, its influence during summer remains weak and inconsistent, allowing localised heat to dominate. Severe monsoon thunderstorms brought localised flash floods, with all of New Mexico's 1 flood this year occurring in the past month as recorded at Extreme Weather tracker.
Looking ahead
Looking ahead, NOAA seasonal forecasts indicate that the moderate El Niño will continue to intensify, with a 93% probability of reaching Very Strong status during autumn and offering the prospect of increased winter precipitation across the region.

FAQs
FAQs
How is the climate in New Mexico changing?
New Mexico is warming in line with the rest of the world. The page above shows the latest monthly temperature anomaly versus the 1961-1990 baseline, the long-term annual trend, and the region's rank in the historical record. The headline panel also shows the long-term trend rate per decade and the warmest and coolest years on file.
What is the climate like in New Mexico?
New Mexico has a arid climate (Köppen BSk: Cold steppe), with both a warm/cold cycle and a wet/dry cycle through the year. July is typically the warmest month, averaging 24.2°C, while January is the coldest at 1.8°C. Annual precipitation averages around 317mm, concentrated mostly in the wet season.
Where does the climate data for New Mexico come from?
Climate data for New Mexico comes from NOAA Climate at a Glance (temperature and precipitation), refreshed every month, when the upstream temperature and rainfall data are refreshed.
What is the climate baseline used on this page?
Anomalies on this page are calculated against the 1961-1990 climatological baseline, which is the standard reference period used by the Met Office, NOAA, IPCC and most national climate services. Some panels also show the source-native 1901-2000 (NOAA) or 1991-2020 (WMO) baselines for verification. See Methodology & Sources for the full reference.
Which areas does the New Mexico climate data cover?
The New Mexico climate profile covers Albuquerque, Las Cruces, Rio Rancho, Santa Fe and surrounding areas. New Mexico climate data from NOAA Climate at a Glance
How often is the New Mexico climate update refreshed?
The New Mexico climate update is refreshed monthly, typically a few days after the previous month closes and the upstream provider (Met Office HadUK-Grid, NOAA Climate at a Glance, Copernicus ERA5 or the Global Carbon Project) publishes its update. See the Climate Rankings for cross-region comparisons.
What counts as a Heatwave Day on the New Mexico climate page?
Heatwave Days use the Warm Spell Duration Index (WSDI) - the WMO/ETCCDI-standard heatwave measure: days that are part of a run of 6 or more consecutive days above the local 90th-percentile temperature for that calendar day. The 90th-percentile threshold varies by time of year (a hot day in January is judged differently to one in July) but is fixed to the 1961-1990 baseline for every year shown - it does not shift as the climate warms, which is why Heatwave Days trend upward over time.
Does the New Mexico climate page include frost and snow data?
Yes. Frost Days (days with a minimum temperature below 0°C, World Bank CCKP) and snow water-equivalent (GPCC) are shown alongside temperature and precipitation, each measured against the 1961-1990 baseline where a like-for-like historical comparison is available.
