How accurate are these tide times?
These are tide predictions, worked out from the movement of the moon and sun
So they are calculated years in advance rather than measured on the day. Amlwch does not have its own tide gauge, so we use the same tide model that we check every month against real Environment Agency gauges at Holyhead, Llandudno and Barmouth, where it matches to within about 15 cm. Expect high and low water times here to be accurate to roughly 10 to 15 minutes.
Not for navigation
These times are a guide for planning a day out, a coastal walk or a photo. They are not for navigation or anything where an exact tide height matters, and weather can push the real sea level above or below any prediction. For navigation, use official Admiralty sources.

About Amlwch tides
Amlwch faces the open Irish Sea on the northern tip of Anglesey. The tidal range here is a little smaller than Liverpool Bay to the east — typically 4–5 metres on spring tides — but the coast is very exposed, so wind and swell can change the actual water level noticeably compared to the prediction.
