Where these times come from. There is no official tide station at Portrane.
These are the Marine Institute's predictions for Skerries, the nearest
official station, 10 km away. Times at Portrane will differ by a few minutes. We do not invent a local
correction, because a made up offset is worse than a stated approximation.

Portrane tide questions
- What time is high tide at Portrane today?
- Today's high water times are shown at the top of this page, taken from the Skerries station 10 km away. There are two high waters roughly every 24 hours and 50 minutes, and local times at Portrane differ from the station by a few minutes.
- Is there an official tide station at Portrane?
- No. The Marine Institute does not predict for Portrane directly. The nearest official station is Skerries, 10 km away, and that is what these times come from. We do not apply an invented local correction.
- What is the best tide for swimming at Portrane?
- This is a shallow shelving strand, so the sea moves a long way. The usable window runs from about three hours before high water to an hour and a half after.
- Which way does Portrane face?
- Portrane faces E, so a wind from that direction is onshore and a wind from the opposite side is offshore.
