In brief

San Francisco is experiencing its hottest March in over two decades, with highs nearing 90°F, while regions like Phoenix and Las Vegas may also set records. Despite the warmth in the western states, the Midwest is still reeling from recent winter storms. Local residents are embracing the heat, although it poses challenges for those without air conditioning.

SAN FRANCISCO (AP) — San Francisco residents are reveling in an unexpected heat wave, experiencing warmer temperatures than usual for March. The city, typically known for its cool summers marked by fog and drizzle, is seeing highs approaching 90°F (32.2°C). This unusual weather is part of a broader heat wave affecting the western U.S. and breaking records in cities like Phoenix and Las Vegas.

As temperatures soar, Phoenix is expected to exceed 100°F (37.7°C) this week — its hottest March on record. Likewise, Las Vegas may also achieve its earliest-ever triple-digit temperature soon, which would certainly alter local tourism dynamics.

While the West is basking in warmth, parts of the Midwest are recovering from significant winter storms that have caused widespread flight cancellations this week. Many residents are adjusting their routines to adapt to the unexpected heat.

Dog owner Justyce Roliz commented on the warm weather, saying, It feels like summer already in March. That’s crazy, but I love it! Meanwhile, Jessica Ling noted the difficulty of coping with high temperatures without air conditioning, opting to spend as much time outdoors as possible.

Record highs were reported Monday, with San Francisco International Airport hitting 83°F (28.3°C) and temperatures in Redwood City reaching 90°F (32.2°C). These figures surpass previous marks set in 2004. As meteorologists note, such early heat waves are not entirely unprecedented, recalling similar conditions in 2005.

In Las Vegas, temperatures may hover between 94°F and 98°F (34.4-36.6°C), which could soon lead to the city recording its earliest occurrence of triple digits in March. Local forecasters are advising residents and visitors to stay hydrated in preparation for the heat.

Weather experts are also warning Arizonians of extreme heat advisories throughout Grand Canyon National Park, with temperatures potentially reaching 104°F (40°C). Visitors are advised to limit strenuous activities during peak heat hours.

This unusual weather pattern follows an uncharacteristically warm winter in Colorado, leading to concerns about water supply as regional utilities begin planning for summer supply stability. The increase in temperatures has intensified existing drought conditions, prompting water conservation efforts.

Overall, this heat wave stands as a reminder of the unpredictability of weather patterns, as communities engage with both the benefits and challenges of such unexpected climate shifts.
