Arizona/California heat wave 2026 – record temps

Entities: Arizona · Los Angeles County Lifeguard Service · Antelope Valley · Los Angeles · National Weather Service

Overview

The June‑July 2026 heat wave that swept Arizona persisted into late July, with monsoonal moisture raising humidity and prompting flood‑risk alerts. After the Extreme Heat Warning expired on July 17, new warnings projected afternoon highs of 106 °F–120 °F across the Phoenix metro area. Phoenix recorded a historic 117 °F on July 24, while nighttime temperatures lingered near 100 °F, straining schools, housing, the power grid and cooling‑center operations. By July 26 daytime highs regularly exceeded 110 °F and overnight lows stayed above 90 °F, prompting extended warnings for Yuma, Imperial County and adjacent regions.

The National Weather Service kept an extreme‑heat warning in place for Los Angeles County and surrounding areas, now extended through August 2. Forecasts call for valley highs of 100‑110 °F, interior peaks of 105‑115 °F and beach temperatures of 80‑90 °F, with ocean water unusually warm at 74 °F off Hermosa Beach and 70 °F off Zuma Beach, adding humidity that makes conditions feel like the Deep South. Heat‑related emergency‑department visits continue to climb, and lifeguards have performed nearly 2,000 rescues in recent days, including about 1,000 on a single Saturday.

A larger‑scale trial of the solar‑reflective pavement coating DuraShield‑SR in Pacoima now covers more than 700,000 sq ft of asphalt. The coating has reduced surface temperatures by over 16 °F and lowered ambient air by up to 3.4 °F, underscoring its potential as a city‑wide heat‑mitigation tool. Officials continue to urge hydration, limited outdoor activity, use of air‑conditioned spaces, and employer‑provided shaded breaks for outdoor workers. The heat is expected to ease briefly early in the week before spiking again Friday‑Sunday, prompting additional advisories and extreme‑heat warnings across the region.
