One wave in seven is higher than the significant height, and about 3 times a day one reaches 0.4 ft. Before heading out, expect waves of up to 0.4 ft.

Cross-shore wind. The coast faces north and the wind blows along the shore: drift and current run parallel to the beach.

Today 88.0–89.1 °F air: 78 / 95 °F
Satellite (2 days ago) 83.8 °F measured 3.1 mi away

The satellite measured 4.1 °F less 2 days ago than the model gives now: the water is probably colder than the forecast says.

Water temperature changes how fish behave: in very cold or very warm water they feed less. The water is steady these days, with no sudden changes.

Water warmer than normal for late October (+2.8 °F).

The best window, 5:00 am to 9:00 am, has glassy water, though with barely any waves.

An estimate for this stretch of coast, not for a specific break: every beach or reef works its own way (its tide, bottom and angle). Check it when you get there.

Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.

Solunar periods

Today's activity: medium
  • 12:44–2:44 am Major · the moon passes overhead · high activity
  • 1:16–3:16 pm Major · the moon passes underfoot · high activity
  • 7:14–8:14 am Minor · moonset · medium activity
  • 8:19–9:19 pm Minor · moonrise · medium activity

According to solunar theory, fish feed more when the moon passes overhead or underfoot (major periods, about 2 h) and when it rises or sets (minor periods, 1 h). It works best around new and full moon.
