Where these times come from. There is no official tide station at Keem Bay.
These are the Marine Institute's predictions for Achill Island, the nearest
official station, 6 km away. Times at Keem Bay will differ by a few minutes. We do not invent a local
correction, because a made up offset is worse than a stated approximation.

Outside the window right now. Next high water 19:20.
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.

Onshore. Keem Bay faces SW, so a WSW wind is blowing in off the sea, choppier water and easier entry drift toward the beach.

Keem Bay tide questions
- What time is high tide at Keem Bay today?
- Today's high water times are shown at the top of this page, taken from the Achill Island station 6 km away. There are two high waters roughly every 24 hours and 50 minutes, and local times at Keem Bay differ from the station by a few minutes.
- Is there an official tide station at Keem Bay?
- No. The Marine Institute does not predict for Keem Bay directly. The nearest official station is Achill Island, 6 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 Keem Bay?
- 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 Keem Bay face?
- Keem Bay faces SW, so a wind from that direction is onshore and a wind from the opposite side is offshore.
