United States – Sidewalks baked, air shimmered, and thermometers surged far beyond seasonal norms as March delivered summer-like heat across much of the country, rewriting record books from coast to coast.
According to NOAA’s Weather Prediction Center, more than 100 locations tied or broke records for their warmest March temperatures, with the most intense heat concentrated across California, the Southwest, and parts of Texas. Some cities recorded highs between 100 and 109°F—levels rarely seen this early in the year.
Across California, Arizona, and Nevada, clusters of deep red markers highlight repeated record-breaking days, with several areas logging 12 or more daily records in a single month. The heat extended into the Plains and Midwest as well, where dozens of cities saw highs in the 80s and 90s—well above average for early spring.
Further east, the impact was less extreme but still notable. Cities from the Ohio Valley to the Northeast recorded multiple daily records, signaling how widespread this early-season warmth became. Even typically cooler regions experienced unusual spikes, accelerating snowmelt and drying out soils earlier than expected.
This pattern matters now. Early heat can stress water systems, boost pollen counts, and increase fire weather risks across already dry regions. It also sets the stage for volatile spring swings, where warmth collides with incoming storm systems.
Looking ahead, longer-range signals point toward above-normal temperatures continuing into late next week across much of the U.S., reinforcing the idea that spring may arrive faster—and hotter—than usual this year.
Are you noticing summer-like warmth already where you live, or has it stayed closer to normal?
