Record-Breaking Heat Hits Southern California This March

Southern California is experiencing an unprecedented heatwave, with record-breaking temperatures recorded on Thursday, March 12. Residents should prepare for ongoing high temperatures as more heat is anticipated over the weekend and into the coming week.

Heat Records Shattered

In Orange County, Santa Ana hit a scorching 97 degrees, surpassing the previous record of 92 degrees set in 2007. According to the National Weather Service (NWS), this is the highest temperature recorded in the area since records began in 1906.

Similarly, Long Beach saw temperatures soar to 92 degrees, tying the record also set in 2007—the highest since the NWS began tracking local temperatures in 1958, according to meteorologist Lisa Phillips.

Factors Contributing to the Heat

A high-pressure system currently parked over the region is preventing any influx of cooler air from lower-pressure systems. Additionally, offshore winds are exacerbating the situation by bringing drier air, leading to what NWS meteorologist Chandler Price described as “never-ending heat.”

Heat Advisory: The NWS has issued a heat advisory for Los Angeles, Orange, San Bernardino, and Riverside counties, effective from Thursday through Friday at 8 p.m. Residents are urged to take precautions against heat stress.

Weekend Weather Forecast

Expect a gradual cooldown beginning this weekend, though temperatures will still remain above average across the region. For Orange County, temperatures are projected to range from the mid-70s to mid-80s.

In the Inland Empire, Saturday temperatures may reach the upper 80s to low 90s. By Sunday, expect highs of low 90s to low 100s. Meanwhile, LA County will experience upper 70s along the coast, while valleys will see temperatures in the 80s.

Upcoming Week Projections

The following week, residents in LA can anticipate valley temperatures hitting the low 100s, while coastal areas will remain in the upper 80s. In Orange County, coastal temps are expected to hover around 80 degrees, and inland areas may see highs in the low to mid-90s.

In inland regions, expect steady temperatures ranging from the mid-90s to the low 100s throughout next week.

Safety Tips During Extreme Heat

With the prolonged heatwave, the National Weather Service warns of significant heat stress, especially in typically cooler coastal areas where cooling systems may not be in place.

• Avoid Outdoor Activities: If possible, complete outdoor tasks early in the day or later in the evening.
• Never Leave Pets or People in Cars: This can lead to dangerous conditions.
• Stay Hydrated: Drink more water than usual, and seek shade as often as possible.
• Be Alert: Be mindful that just because it’s March, heat exhaustion remains a risk.

“This heat is very out of the ordinary,” Price cautions. Residents should remain vigilant and prioritize their health during this extreme weather event.
