Where this tide comes from
Isla Cristina has no tide station nearby: its tide is calculated with the global FES2022 model, from the nearest model cells offshore (the first one 2.5 mi away). It may differ from the real tide by a few minutes and inches, and more with wind or storms. Heights are above mean sea level, not chart datum, so low tides are negative. Not for navigation.
Model attribution: FES2022 Tide was produced by LEGOS, NOVELTIS and CLS, funded by CNES, and distributed by AVISO (https://doi.org/10.24400/527896/a01-2024.004), AVISO licence (https://www.aviso.altimetry.fr/fileadmin/documents/data/License_Aviso.pdf). Modified by TidePlanet: constants interpolated from the nearest model cells offshore; heights above mean sea level.
The sea at Isla Cristina
Sea stateSea state: calm (rippled)
The waves you may find
- Most commonMost common0.2 ft
- Significant0.3 ft
- Highest expectedHighest0.7 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 0.7 ft. Before heading out, expect waves of up to 0.7 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.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Friday 30: 1.8 ft with a period of 5 s, from the south-southeast (slight).
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.

Your diving day at a glance
The best window, 9:30 am to 11:00 am, combines slack water at low tide, little swell, light wind, weak current and the sun high. Also good from 3:30 pm to 5:00 pm, with slack water at high 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.

Moon phase and position
Today the moon is 226,461 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:52–3:52 am Major · the moon passes overhead · high activity
- 2:24–4:24 pm Major · the moon passes underfoot · high activity
- 10:08–11:08 am Minor · moonset · medium activity
- 7:36–8:36 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. Shallow, gradual bottom (16 ft at 0.6 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 1.7 mi. For dives deeper than 33 ft, go by boat.
