Tides in Hydra
Today's high and low tides
- ▲ High tide 3:57 am 0.1 ft
- ▼ Next low tide 11:34 am -0.1 ft
↓ Falling The tide is falling. 1 h 39 min to low tide at 11:34 am.
In Hydra the astronomical tide is very small: about 0.3 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 June 15 (0.2 ft) and the lowest, on February 1 (-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 Hydra. 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). Modified by TidePlanet: constants interpolated from the nearest model cells offshore; heights above mean sea level.
The sea at Hydra
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.7 ft
- Significant1.3 ft
- Highest expectedHighest2.8 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.8 ft. Before heading out, expect waves of up to 2.8 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 southeast 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 Tuesday 3: 4.1 ft with a period of 5 s, from the south (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.

Surf in Hydra today
Surf today
Flat- Barely any waves (0.5 ft sets): flat
- Moderate offshore wind (17 mph): it holds up and grooms the waves
It’s flat today: almost no waves reach this coast.
- Light: First light 6:21 am · sunrise 6:48 am · sunset 5:32 pm · last light 5:59 pm
- Tide: We don’t have a reliable tide to show here.
- Water at 71.4 °F: a springsuit or a 2 mm fullsuit.
- Energy: 2 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 barely any waves.
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 Hydra today
Diving and snorkeling today
Likely visibility: good- 0.9 ft swell at 4 s from the northeast: barely any surge
- Light offshore wind (11 mph)
- 0.5 mph current toward the east-northeast, weak (model)
- Daylight
- Slack water today: none; the tide doesn't count here
- Likely visibility: good. Rain (0.31 in) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 71.4 °F: a 5 mm wetsuit.
- Snorkeling: good, calm sea and light wind.
- Night dive: dark from 5:59 pm. Waning gibbous (86%), rising at 7:58 pm: a bright night.
Your diving day at a glance
The best window, 4:30 pm to 5:30 pm, combines little swell, light wind and weak current. Also worth a look from 9:10 am to 12:10 pm, with little swell, weak current and the sun high, though with moderate wind.
In Hydra 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 Hydra
Moon phase and position
Today the moon is 226,597 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 1:47–3:47 am Major · the moon passes overhead · high activity
- 2:20–4:20 pm Major · the moon passes underfoot · high activity
- 10:11–11:11 am Minor · moonset · medium activity
- 7:28–8:28 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.
