Best window today
Outside the window right now. Next high water 15:00. 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.
Wind and sea
Keem Bay faces SW. A WNW wind is blowing along the beach, expect a lateral drift.

Questions
What time is high tide at Keem Bay today?
Today's times are 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.
