Today’s Tide Times When can you cross? Tide heights are affected by the weather and can surprise you. If you absolutely must get across, and the predicted tide height is 4.9m or above, allow about 1 hour either side of the high tide time. Allow an extra 30 mins if it is over 5.5m.
The biggest tides usually happen when high tide is due between about 12 and 3.30. Outside these times you will probably be fine to cross.
Remember sea water is very bad for car engines so its better to sit and enjoy the view while you wait.
