Bars compare daily height differences at this station within this seven-day window. They are not a continuous water-level curve or current speed. The scale changes with the window.

How are the Moon and sea connected?

The Moon and Sun’s tidal effects reinforce each other around new and full moons, generally producing larger tidal ranges. Ranges tend to be smaller around quarter moons.

Coast shape, water depth and local timing also matter. Lunar phase alone does not establish this station’s spring or neap tide dates.

BEFORE THE COAST

Before you head to the coast

A tide timetable is not a sea-condition forecast. Check the sea area, forecast time and on-site restrictions separately.

Marine wind: Available for today
Wave height: Available for today
Water current: Available for today
Weather warnings: Available for today

Current observations: wind at the port gauge, waves and currents at a separate offshore buoy. They may differ from your beach. Missing or outdated readings are withheld.

Forecast and on-site guidance

Official pages open separately. Select your sea area and check the issue time and forecast period. This page does not transfer the port or selected date to those sites.

Local access restrictions are not checked here. Confirm with the site operator and follow posted restrictions.

Not for navigation, entering the water, or deciding when to cross tidal flats. No entry, exit or fishing-success prediction is provided.

Reading this timetable

High and low tide: The high and low points of predicted water level at this port. They do not establish when the current stops.
Tide and current: Tides describe water-level changes; currents describe horizontal flow. This timetable does not calculate current speed.
Predicted height and depth: Tidal height needs a stated reference level. The reference level is unverified here; do not read centimetres as water depth or clearance.

A prediction for a port does not apply unchanged to every nearby beach or tidal flat.
