Миттєва Погода — Instant Weather — Coastal Weather, Tide Times and Swimming Conditions

From the English Channel to the Mediterranean and the Atlantic coast, the Beach Weather page brings together marine data to plan a day by the sea, a surf session or coastal sailing.

Marine Information for Swimming and Water Sports

High tide, low tide times and tide coefficients

Check exact high and low water times along with the daily tide coefficient (from 20 to 120). Above coefficient 90 (spring tides), tidal range and rip currents strengthen significantly.

Sea water temperature and swell state

Each beach sheet displays sea surface temperature, significant wave height in meters, swell period in seconds and coastal thermal breeze direction.

Sun protection and swimming safety

A synthetic indicator evaluates swimming safety based on sea state and wind speed, paired with hourly UV tracking.

Frequently Asked Questions — Beaches & Tides

What is a rip current (baïne) on the Atlantic coast?

A baïne is a natural sandbar pool that empties during ebb tide, creating a strong seaward current. If caught, swim parallel to the shoreline rather than against the current.

Why is a long-period swell (over 12 seconds) more powerful?

Long-period swells originate from distant ocean storms, carrying greater deep-water energy that builds into larger wave sets near coastal sandbars.

Why is it often cooler on the beach than 10 km inland?

In the afternoon, rapid inland heating creates a thermal sea breeze that draws temperate marine air onto the shore.
