Tides in Therasia
Today's high and low tides
- ▲ High tide 1:12 am 0.2 ft
- ▼ Next low tide 8:54 am -0.1 ft
- ▲ High tide 1:18 pm 0.0 ft
- ▼ Low tide 5:54 pm -0.1 ft
↓ Falling The tide is falling. 6 h 45 min to low tide at 8:54 am.
In Therasia the astronomical tide is very small: about 0.2 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 December 25 (0.2 ft) and the lowest, on August 12 (-0.2 ft).
Heights above mean sea level. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. mean sea level

Where this tide comes from
Tides from the FES2022 station (AVISO/CNES), 1.2 mi from Therasia. Times and heights are its predictions.
Station data 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).

The sea at Therasia
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.2 ft
- Significant2.4 ft
- Highest expectedHighest5.0 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.0 ft. Before heading out, expect waves of up to 5.0 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-shore wind. The coast faces west and the wind blows along the shore: drift and current run parallel to the beach.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Wednesday 4: 5.1 ft with a period of 6 s, from the west-southwest (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 about normal for late October.

Surf in Therasia today
Surf today
Poor- 1.7–2.6 ft surf at the shore, a fun size for most surfers
- 1.4 ft swell at 5 s from the west-southwest, short: weak, messy waves
- 2.6 ft wind swell at 3 s: messy waves
- Light cross-shore wind (7 mph): a bit of chop
- First or last light of the day
- Light: First light 6:12 am · sunrise 6:39 am · sunset 5:26 pm · last light 5:52 pm
- Tide: We don’t have a reliable tide to show here.
- Water at 70.3 °F: a springsuit or a 2 mm fullsuit.
- Energy: 24 kJ · Low power
Today’s surf at a glance
The best window is 6:12 am to 10:00 am, though with 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.
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 Therasia today
Diving and snorkeling today
Likely visibility: fair- 1.6 ft swell at 4 s from the west-northwest: some surge on the bottom
- Light onshore wind (11 mph)
- 0.4 mph current toward the southwest, weak (model)
- Sun high: more light underwater
- Slack water today: none; the tide doesn't count here
- Likely visibility: fair. Swell (up to 3.8 ft at 5 s) and rain (0.26 in) over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 70.3 °F: a 5 mm wetsuit.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 5:52 pm. Waning gibbous (86%), rising at 7:53 pm: a bright night.
Your diving day at a glance
The best window, 11:30 am to 2:30 pm, combines light wind, weak current and the sun high.
In Therasia 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 Therasia
Moon phase and position
Today the moon is 226,597 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 1:39–3:39 am Major · the moon passes overhead · high activity
- 2:12–4:12 pm Major · the moon passes underfoot · high activity
- 10:00–11:00 am Minor · moonset · medium activity
- 7:23–8:23 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
Deepens quicklyThe bottom deepens quickly: 33 ft of water 0.25 mi from shore. It reaches 164 ft at 0.75 mi.
From the shoreline (1.2 mi from Therasia) out to sea, heading west.

- 33 ft deep0.25 mi
- 66 ft deep0.65 mi
- 164 ft deep0.75 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 14 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
- Swimming. The bottom drops quickly near the shore and you are soon out of your depth. Keep an eye on kids and weak swimmers.
- Diving. Shore diving works here: 33 ft at 0.25 mi and 66 ft at 0.65 mi from shore.
