Albuquerque Just Rewrote Its March Temperature Record Books — 8 of the 10 Hottest March Days Ever Recorded Happened in the Last Week and a Half
ALBUQUERQUE, NM — The heat wave is over — but what it left behind in Albuquerque’s record books will stand for a very long time. In a city that has been keeping weather records since 1891, the last week and a half of March 2026 just did something that 135 years of meteorological history had never managed to do. Eight of the ten hottest March days ever recorded in Albuquerque happened between March 18 and March 26, 2026. Not over decades. Not over years. In eleven days.
The Record That Stopped Everyone Cold
Before this heat wave arrived, there was one temperature barrier that Albuquerque had never crossed in the month of March — not once in 135 years of record-keeping dating back to December 1891. A 90-degree day in March had never been recorded in Albuquerque prior to May 3. The city simply did not reach 90°F in March. That was the rule. March 2026 broke that rule — twice.
On March 21, 2026, Albuquerque recorded a 1-day mean maximum temperature of 91.0°F — the single hottest March day in the city’s entire recorded history. Four days later, on March 25, the city hit 90.0°F again — the second time in history that Albuquerque crossed the 90-degree threshold in March, and it happened in the same week.

Look at that table carefully. The top 8 spots in 135 years of Albuquerque March temperature history — six of them belong to a single 11-day stretch in 2026. The only previous entries that appear in the top 10 are a 85.0°F reading from March 26, 1971 and another from March 19, 1907. Everything else was rewritten this month.
What This Means in Plain Terms
For residents who lived through this heat wave, here is the context that puts it into perspective. When Albuquerque hit 91°F on March 21, the city was experiencing a temperature that had never been observed in March in 135 years of weather records. That is not a record that gets broken every few years. That is a record that had stood through two World Wars, the Great Depression, and every El Niño and La Niña cycle since the 1890s — and it fell in a single afternoon.
The 90°F barrier is especially significant. Prior to this month, Albuquerque had never recorded a 90-degree day before May 3 — full stop. The city crossed that barrier twice in five days during the third week of March 2026.

State-by-State Impact
🔴 New Mexico — Albuquerque / Bernalillo County — Ground zero for the most historically significant readings of this entire heat wave. All-time March record set at 91.0°F. Eight of ten hottest March days ever recorded came in the last 11 days. A 90°F day in March — something that had never happened in 135 years — occurred twice.
🔴 New Mexico — Statewide — Albuquerque’s records reflect a broader statewide pattern. New Mexico was among the hardest-hit states during the March 15–26 peak of the heat wave, with monthly temperature records broken at multiple stations across the state.
🟠 Arizona, Nevada, Southern California — Also saw historic monthly records during this same event window, with some stations recording temperatures in the 100–109°F range. The Southwest as a region experienced its most anomalous March heat in the modern observational record.
🟡 Colorado, Utah — Above-normal warmth with some daily records broken but less extreme than the core Southwest heat zone.
The Heat Is Gone — The Records Are Permanent
Albuquerque’s thermometers are finally returning to something resembling normal March temperatures. But what this heat wave accomplished in eleven days will sit at the top of the city’s climate record books indefinitely. 91.0°F in March. Two 90-degree days before the calendar even reached spring. Eight entries in the all-time top 10 — rewritten in under two weeks.
The heat wave is over. The history it made is not going anywhere.
