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

The Forty Foot tide questions
- What time is high tide at The Forty Foot today?
- Today's high water times are shown at the top of this page, taken from the Dublin station 10 km away. There are two high waters roughly every 24 hours and 50 minutes, and local times at The Forty Foot differ from the station by a few minutes.
- Is there an official tide station at The Forty Foot?
- No. The Marine Institute does not predict for The Forty Foot directly. The nearest official station is Dublin, 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 The Forty Foot?
- This is a slip, steps or pier entry, so depth arrives with the tide. The usable window is roughly two hours either side of high water.
- Which way does The Forty Foot face?
- The Forty Foot faces E, so a wind from that direction is onshore and a wind from the opposite side is offshore.
