The waves you may find
- Most commonMost common0.2 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.0 ft. Before heading out, expect waves of up to 1.0 ft.
Wind on the coast and offshore
Offshore wind. The coast faces south and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.

Waves build over the next few days. The biggest waves arrive on Monday 2: 2.4 ft with a period of 4 s, from the northwest (slight).

Today’s surf at a glance
The best window, 6:00 am to 10:00 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.

Your diving day at a glance
The best window, 9:20 am to 11:00 am, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also good from 3:20 pm to 4:50 pm, with slack water at low tide, little swell, light wind and weak current.
Slack water comes from the tide: in inlets, channels and between islands the water can keep running for an hour or two after. Ask the local dive shop.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Moon phase and position
Today the moon is 226,461 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 12:22–2:22 am Major · the moon passes overhead · high activity
- 12:54–2:54 pm Major · the moon passes underfoot · high activity
- 8:51–9:51 am Minor · moonset · medium activity
- 5:52–6:52 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.

Water depth

- 66 ft deep1.1 mi

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 0.95 mi): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. Shallow near shore: you only reach 33 ft at 0.95 mi. For dives deeper than 33 ft, go by boat.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
