Record Heat Dome Brings Triple-Digit Temps, Broken Records to Yuma

Yuma is baking under conditions that belong in June, not mid-March, as a record-breaking 594 DM heat dome stretching from Los Angeles to Yuma takes hold and refuses to let go through late March. Temperatures have already climbed into the low to mid-90s, running roughly 15 degrees above normal for this time of year, and the worst is still ahead.

The heat arrived with immediate force. El Centro tied its record high of 95 degrees for the date, and forecasters say many more records will fall across the region over the next 7 to 10 days. A very strong ridge of high pressure is locked in place, keeping conditions well above normal through the weekend, with mid to upper 90s expected before the first round of triple-digit temperatures arrives next week.

"These type of temperatures and heat are very unseasonable, and it's a big deal to see triple-digits for early March," KYMA meteorologists reported. The outlet is tracking daily record highs as likely for multiple days starting later this week, with highs climbing into the low 100s by next week.

The heat dome, measured at 594 DM, is expected to intensify rather than relax. An even stronger ridge is forecast to build next week, pushing temperatures hotter still in the back half of the month. High humidity is compounding the misery, making conditions feel like full summer, with lingering moisture forecast to exacerbate the heat wave through late March.

Heat risk levels are escalating in step with the thermometer. A widespread Minor Heat Risk is in effect later this week, with forecasters warning that conditions will upgrade to Moderate Heat Risk levels next week as triple digits settle in.

For context on how extraordinary this stretch is: the earliest Yuma has ever recorded a triple-digit temperature is March 12, 1916. The current heat dome is on pace to test or surpass that historical benchmark repeatedly.

KYMA issued a direct advisory for Yuma County's large population of winter visitors and seasonal residents, many of whom are unaccustomed to desert heat of this magnitude. Knowing the signs and symptoms of heat exhaustion and heat stroke, staying hydrated, and limiting outdoor exposure during peak afternoon hours are critical precautions as the region heads into the most intense phase of this prolonged weather event.
