Southern California Endures Record Humidity Amid Heat Wave
US · Published Sep 9, 2026
Southern California is experiencing some of the most oppressive humidity on record, with dew points reaching 76°F (24°C) in Long Beach, Huntington Beach, and Newport Beach.
The high humidity is attributed to Tropical Storm Marie, which is sending tropical moisture into the region, combined with a ridge of high pressure from the east.

Impact & Risks

The combination of extreme heat and high humidity is creating significant heat stress, particularly for vulnerable populations such as the elderly, children, and those with pre-existing health conditions. The high humidity is making it difficult for the body to cool down, increasing the risk of heat-related illnesses. Coastal areas are also facing dangerous rip currents, high surf, and potential ocean pollution due to recent rainfall. Residents are advised to avoid swimming in the ocean and to take precautions against heat stress.
