- ▼ Low tide 3:11 am 0.6 ft
- ▲ High tide 9:26 am 1.3 ft

In Platja de Port-alguer the astronomical tide is very small: about 0.7 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 November 27 (1.3 ft) and the lowest, on February 3 (0.1 ft).
Heights above chart datum: the lowest astronomical tide (LAT), the zero of nautical charts in Europe. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. chart datum (LAT)

The sea at Platja de Port-alguer
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.0 ft
- Significant2.0 ft
- Highest expectedHighest4.2 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.2 ft. Before heading out, expect waves of up to 4.2 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-offshore wind. The coast faces east 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: 4.5 ft with a period of 5 s, from the north-northeast (moderate).
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 66.7 °F by Tuesday 3.
Water warmer than normal for late October (+4.1 °F).

- 2.4 ft wind swell at 3 s: messy waves
- Moderate offshore wind (16 mph): it holds up and grooms the waves
- Light: First light 6:46 am · sunrise 7:15 am · sunset 5:46 pm · last light 6:15 pm
- Tide: We don’t have a reliable tide to show here.
- Water at 67.6 °F–68.5 °F: a springsuit or a 2 mm fullsuit.
- Energy: 11 kJ · Low power
Today’s surf at a glance
The best window, 7:00 am to 11:00 am, has light offshore wind, though with small waves, a short-period swell and wind 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.

The moon in Platja de Port-alguer
Moon phase and position
Today the moon is 226,461 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:08–3:08 am Major · the moon passes overhead · high activity
- 1:39–3:39 pm Major · the moon passes underfoot · high activity
- 9:43–10:43 am Minor · moonset · medium activity
- 6:32–7:32 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.

For fishing, swimming and diving
- Shore fishing. 33 ft of water just 1,100 ft from shore: a good cast reaches deep water. Current and surf hit harder here.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. Shore diving works here: 33 ft at 1,100 ft and 66 ft at 0.4 mi from shore.
The profile is turned slightly from the coast so it does not run into an island or a headland.
