About this spot

About

San Gabriel Rivermouth (Long Beach) is a sheltered rivermouth/jetty surfing spot near Seal Beach that’s known for rarely producing truly rideable waves. When it does line up, the break is generally small, with a mellow, soft feel that suits beginner-friendly sessions—particularly for longboarding. The spot is best at low tide, and the jetty/rivermouth layout offers some protection compared with more exposed stretches of coast. Conditions are typically about soft, mushy waves, often peaky in shape, with short rides rather than long, continuous lines. Safety is a major consideration here. Reported hazards include rocks and pollution, and stingray risk is repeatedly emphasized; rainfall can also worsen runoff impacts and increase the likelihood of debris in the water. Local guidance also stresses staying out of the active river channel during heavy discharge. Water temperature is consistently warmer than surrounding coastal areas due to thermal discharge, with winter generally around the mid-teens Celsius and late-summer warming into the low-to-mid 20s °C (depending on the month). Wind can help or hinder: the area is associated with sea-breeze behavior, and sessions are most favorable when offshore winds keep the surface cleaner—while afternoon westerlies are more likely to make things choppier.
