Where this tide comes from
Greenisland has no station of its own, so we use the tide at Bangor (Environment Agency), 8.5 mi away. On the open coast the difference is usually a few minutes and inches; inside estuaries, rivers and enclosed bays it can be much larger.
Station data attribution: This uses Environment Agency tide gauge data from the real-time data API (Beta): Bangor (E73824), https://environment.data.gov.uk/flood-monitoring/id/stations/E73824. Contains public sector information licensed under the Open Government Licence v3.0 (https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/).

Wind on the coast and offshore
Cross-shore wind. The coast faces east and the wind blows along the shore: drift and current run parallel to the beach.

Waves stay much the same all week. The biggest waves arrive on Friday 30: 2.4 ft with a period of 4 s, from the south-southeast (slight).

The best window, 11:00 am to 1:00 pm, combines slack water at high tide, little swell, light wind and the sun high.
Slack water comes from the tide: in inlets, channels and between islands the water can keep running for an hour or two after. Ask the local dive shop.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

The moon in Greenisland
Moon phase and position
Today the moon is 226,451 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 12:46–2:46 am Major · the moon passes overhead · high activity
- 1:18–3:18 pm Major · the moon passes underfoot · high activity
- 10:34–11:34 am Minor · moonset · medium activity
- 4:55–5:55 pm Minor · moonrise · medium activity
According to solunar theory, fish feed more when the moon passes overhead or underfoot (major periods, about 2 h) and when it rises or sets (minor periods, 1 h). It works best around new and full moon.
