California Faces 32 to 46 mph Winds With Gusts Over 55 mph and 12 to 14 Foot Seas From Big Sur and Morro Bay Through Point Conception Saturday May 16 Through Sunday May 17

MORRO BAY, California — Hazardous marine conditions are developing along the California coast from Big Sur southward through Cambria, Morro Bay, San Luis Obispo and Point Conception, with moderate gale-force to fresh gale-force northwesterly winds of 32 to 46 mph and gusts exceeding 55 mph forecast to develop Saturday, May 16 through Sunday, May 17, 2026.

Seas and swell are expected to build to 12 to 14 feet with a 5 to 11 second period, creating extremely dangerous conditions for any mariners along this stretch of the California coast through the weekend.

Wind and Wave Forecast Saturday Through Sunday

The wind and wave forecast map shows the most intense conditions concentrated along the immediate California coastline from Big Sur southward through Point Conception:

• Northwesterly winds of 32 to 46 mph with gusts over 55 mph are forecast to develop along the coast from Big Sur through Point Sierra Nevada, Cambria, Morro Bay, Los Osos, San Luis Obispo, Point Buchon, Point San Luis Lighthouse, Point Sal, Santa Maria, Lompoc, Point Arguello and Point Conception beginning Saturday, May 16.
• The strongest winds shown in pink and magenta on the map are concentrated directly along the immediate coastline, with winds decreasing as you move inland toward Paso Robles, San Luis Obispo and Santa Maria.
• Seas and swell building to 12 to 14 feet with a 5 to 11 second period will create extremely rough and dangerous ocean conditions along the entire outlined coastline through Sunday, May 17.

What Gale-Force Winds Mean for Mariners

Gale-force winds are one of the most serious marine hazards and represent a significant step up in danger from typical windy conditions at sea:

• Moderate gale-force winds of 32 to 46 mph are capable of producing breaking wave crests, large waves and dramatically reduced visibility from sea spray along the California coastline from Big Sur to Point Conception through Sunday, May 17.
• Gusts exceeding 55 mph on top of sustained 32 to 46 mph winds can make vessel control extremely difficult or impossible for smaller and medium-sized boats operating between Morro Bay, Point Buchon and Point Conception this weekend.
• Seas of 12 to 14 feet combined with a 5 to 11 second wave period means waves will be arriving frequently and at significant height, creating conditions capable of capsizing vessels and making rescue operations extremely difficult along this stretch of the California coast.

Ocean Upwelling and Water Temperature Drop

The strong northwesterly winds forecast for Saturday through Sunday will also drive a significant oceanographic event along the California coast:

• These gale-force northwesterly winds will generate significant ocean upwelling, a process where strong winds push warm surface water away from the coast and pull cold water up from the deep ocean to replace it.
• Upwelling driven by this weekend’s winds will lower seawater temperatures along the California coast to 49 and 51 degrees, creating an additional life-threatening hazard for anyone who ends up in the water.
• Water temperatures of 49 to 51 degrees can cause cold shock and incapacitation within minutes of immersion, meaning even a brief accidental entry into the ocean near Morro Bay, Point Buchon or Point Conception this weekend could be fatal without immediate rescue.

Safety Actions for This Weekend

All mariners and coastal visitors along the California coast from Big Sur to Point Conception should take the following steps before Saturday, May 16:

• Do not venture out on the water between Big Sur and Point Conception this weekend. Gale-force winds of 32 to 46 mph with gusts over 55 mph and seas of 12 to 14 feet are beyond safe operating conditions for the vast majority of recreational and small commercial vessels.
• If you are currently at sea along the California coast near Morro Bay, Cambria or Point Arguello, seek safe harbor immediately before Saturday conditions develop and do not return to open water until the gale-force wind and wave threat passes.
• Coastal visitors at beaches near Morro Bay, Lompoc and Santa Maria should stay well back from the water’s edge this weekend as 12 to 14 foot waves can surge well up onto beaches without warning.
