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 Petita de Portbou
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.0 ft
- Significant2.1 ft
- Highest expectedHighest4.5 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.5 ft. Before heading out, expect waves of up to 4.5 ft.
Wind on the coast and offshore
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: 5.1 ft with a period of 5 s, from the north (moderate).
Water temperature
Water temperature →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 (+4.3 °F).

Moon phase and position
Today the moon is 226,461 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:09–3:09 am Major · the moon passes overhead · high activity
- 1:40–3:40 pm Major · the moon passes underfoot · high activity
- 9:44–10:44 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.
