Surf at the primary beach breaks (Morro Rock & Atascadero State Beach) is running knee to waist high on open sets. Exposed outer peaks and reefs are occasionally touching chest high on longer-period pulses. Wave energy is clean but soft due to moderate swell periods and morning high tides.
Current conditions at Morro Bay Harbor feature patchy fog and light air. Air temperature is currently 58°F with an expected high of 64°F today. Current winds are calm to light SSW at 2–3 mph. Wind trend: calm light-and-variable conditions early morning will turn to moderate onshore NW winds by midday, building into late afternoon.
High Tide: 4:08 AM (2.7 ft)
Low Tide: 8:12 AM (2.1 ft)
High Tide: 3:24 PM (4.3 ft)
Low Tide: 11:21 PM (0.5 ft)
CDIP 193 (Point Buchon) / CDIP 076 (Diablo Canyon): Primary swell direction is WNW (285°–295°) at 2.5 ft @ 11 seconds. Secondary swell direction is SSW (190°–200°) at 1.5 ft @ 14 seconds.
Surf Trend: Waves will hold in the knee-to-waist high range through the afternoon, becoming bumpy as onshore winds pick up. Tomorrow will see a slight reinforcing bump in WNW swell energy, maintaining waist-to-chest high waves across best breaks with typical early light winds followed by afternoon NW chop.
