Where this tide comes from
Sines Municipality has no tide station nearby: its tide is calculated with the global FES2022 model, from the nearest model cells offshore (the first one 1.6 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 Sines Municipality
Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.2 ft
- Significant6.5 ft
- Highest expectedHighest13 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 13 ft. Before heading out, expect waves of up to 13 ft.
Wind on the coast and offshore
Offshore wind. The coast faces west 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 ease over the next few days. The biggest waves arrive on Thursday 29: 7.1 ft with a period of 12 s, from the west-northwest (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 colder than normal for late October (−1.5 °F).

Surf in Sines Municipality today
Surf today
Good- 4.3–6.7 ft surf at the shore, a good size with some punch
- 5.6 ft swell at 9 s from the northwest, a bit short
- Light offshore wind (4 mph): it holds up and grooms the waves
- Falling tide (low tide at 10:09 am)
- Light: First light 6:31 am · sunrise 6:58 am · sunset 5:40 pm · last light 6:07 pm
- Tide: high 3:55 am (4.7 ft), low 10:09 am (-4.5 ft), high 4:24 pm (4.0 ft) and low 10:26 pm (-3.8 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.
- Water at 63.0 °F: a 3/2 fullsuit.
- Energy: 502 kJ · High power
Today’s surf at a glance
The best window, 8:00 am to 12:00 pm, has a good size and light offshore wind. 4:00 pm to 6:00 pm also works, with a good size.
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.
Diving in Sines Municipality today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (10:09 am): little current from 9:50 am to 10:30 am
- 5.4 ft swell at 9 s from the northwest: strong surge on the bottom
- Light offshore wind (4 mph)
- 0.2 mph current toward the south, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 3:55 am (3:30–4:20 am), low tide 10:09 am (9:50–10:30 am), high tide 4:24 pm (4:00–4:50 pm) and low tide 10:26 pm (10:00–10:50 pm)
- Likely visibility: poor. Swell (up to 8.2 ft at 11 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 63.0 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:07 pm. Waning gibbous (85%), rising at 8:11 pm: a bright night.
Your diving day at a glance
The best window, 9:20 am to 11:00 am, combines slack water at low tide, light wind, weak current and the sun high, though with a big swell. Also worth a look from 2:30 pm to 5:20 pm, with slack water at high tide and light wind, though with some swell and 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 226,641 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 2:02–4:02 am Major · the moon passes overhead · high activity

- 10:29–11:29 am Minor · moonset · medium activity
- 7:41–8:41 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.
