BEST HOURS · 48 H (DAYLIGHT)

How is the rating calculated?

	Wind	Gusts	Waves
Go	≤ 7 m/s (≈ 14 kn) up to 4 Beaufort	≤ 10 m/s (≈ 19 kn)	≤ 0,6 m
Caution	≤ 10 m/s (≈ 19 kn) 5 Beaufort	≤ 13 m/s (≈ 25 kn)	≤ 1,0 m
Not recommended	> 10 m/s 6+ Beaufort	> 13 m/s	> 1,0 m

Thresholds for a small boat (under 5 m, engine, experienced) — the same as in “⛵ My boat”; with a profile they adapt to you. The rating takes the worst of the next 3 hours. Outside daylight, thunderstorms or gusts above the limit → “Not recommended”; fog or missing wave data → at most “Caution”.

This is guidance, not an official warning. Before going out, check the HNMS (EMY) marine forecast, MeteoAlarm (Greece), the official warnings and any orders of the Hellenic Coast Guard. In an emergency: 112 or 108 (Coast Guard).

The sea at Chios: what to know

The forecast on this page is for a sea point off Chios (38.37° N, 26.17° E), in the North-east Aegean. Values come from the Open-Meteo forecast and marine models (MET Norway as backup) and are updated several times a day.

More about the sea at Chios: wind, traffic, how to read the numbers

The strait between Chios and the Turkish coast channels north winds; with strong northerlies the sea off Chios town can be rough, while southerly winds bring waves to the east coast.

Chios has a long shipping tradition and its port serves ferries to Piraeus, Lesvos and Çeşme. Through traffic between the Dardanelles and the south passes west and east of the island.

How to read the numbers: wind up to about 10 knots and waves under 0.5 m are usually comfortable for a small boat or SUP near the coast. Waves from 1 m and gusts above 22 knots are already serious for boats under 6 m. The rating follows the boat profile you choose.

Questions and answers

How big are the waves at Chios today?

The current significant wave height in metres and its period are in the “Now” block at the top, and hour by hour in the 48-hour chart. Values come from the Open-Meteo marine model.

What is the sea temperature at Chios?

We show the model sea-surface temperature at a point offshore. Close to the beach the water can differ by 1–2 °C, especially after a strong wind.

When is it dangerous to go out by boat at Chios?

With the default small-boat profile, gusts above 22 knots or waves above 1 m give “Not recommended”. Always check the official HNMS forecast, the official warnings and any sailing ban of the Coast Guard before going out.
