Where these times come from. There is no official tide station at Rathmullan.
These are the Marine Institute's predictions for Buncrana, the nearest
official station, 6 km away. Times at Rathmullan 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 19:50.

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