Tides in Castelsardo
Today's high and low tides
- ▼ Low tide 4:58 am 0.1 ft
- ▲ Next high tide 11:12 am 1.0 ft
- ▼ Low tide 6:02 pm 0.4 ft
- ▲ High tide 10:43 pm 0.8 ft
↑ Rising The tide is rising. 5 h 32 min to high tide at 11:12 am.
In Castelsardo the astronomical tide is very small: about 0.8 ft between high and low tide. Here the sea level is moved mostly by wind and air pressure (storm surge), which can raise or lower it more than the tide itself.
2026 extremes: the highest tide of the year is on September 26 (1.0 ft) and the lowest, on February 3 (-0.4 ft).
Heights above MLWS. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. MLWS

The sea at Castelsardo
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.8 ft
- Significant1.6 ft
- Highest expectedHighest3.4 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.4 ft. Before heading out, expect waves of up to 3.4 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces north and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Monday 2: 3.9 ft with a period of 6 s, from the north-northwest (slight).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water cools over the next few days: about 67.4 °F by Wednesday 4.
Water warmer than normal for late October (+5.3 °F).

Today’s surf at a glance
The best window, 6:24 am to 10:00 am, has light offshore wind, though with small waves and a short-period swell.
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, 9:10 am to 12:10 pm, combines little swell, light wind, weak current and the sun high.
In Castelsardo the tide barely moves the water, so there's no slack to wait for: swell, wind and current are what count.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

The moon in Castelsardo
Moon phase and position
Today the moon is 226,618 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 1:49–3:49 am Major · the moon passes overhead · high activity
- 2:21–4:21 pm Major · the moon passes underfoot · high activity
- 10:27–11:27 am Minor · moonset · medium activity
- 7:15–8:15 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 deep0.75 mi
- 164 ft deep1.7 mi
For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 0.3 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. Shore diving works here: 33 ft at 0.45 mi and 66 ft at 0.75 mi from shore.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
