Where these times come from. There is no official tide station at Rossnowlagh.
These are the Marine Institute's predictions for Killybegs, the nearest
official station, 16 km away. Times at Rossnowlagh will differ by a few minutes. We do not invent a local
correction, because a made up offset is worse than a stated approximation.

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

Rossnowlagh tide questions
- What time is high tide at Rossnowlagh today?
- Today's high water times are shown at the top of this page, taken from the Killybegs station 16 km away. There are two high waters roughly every 24 hours and 50 minutes, and local times at Rossnowlagh differ from the station by a few minutes.
- Is there an official tide station at Rossnowlagh?
- No. The Marine Institute does not predict for Rossnowlagh directly. The nearest official station is Killybegs, 16 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 Rossnowlagh?
- 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 Rossnowlagh face?
- Rossnowlagh faces WSW, so a wind from that direction is onshore and a wind from the opposite side is offshore.
