The sea at Letterfrack
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.5 ft
- Significant5.0 ft
- Highest expectedHighest10.0 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 10.0 ft. Before heading out, expect waves of up to 10.0 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces northwest and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves ease over the next few days. The biggest waves arrive on Wednesday 28: 9.1 ft with a period of 10 s, from the west-southwest (rough).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water is steady these days, with no sudden changes.

Diving in Letterfrack today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (12:30 pm): little current from 12:10 pm to 12:50 pm
- 7.4 ft swell at 9 s from the west: strong surge on the bottom
- Moderate onshore wind (14 mph)
- 0.6 mph current toward the east-northeast (model)
- Sun high: more light underwater
Not a day for shore diving: swell, wind, current or storms during the best window. If you go, go with a dive shop and only if they give the OK.
- Slack water today: low tide 12:05 am (11:50 pm–12:20 am), high tide 6:17 am (6:00–6:40 am), low tide 12:30 pm (12:10–12:50 pm) and high tide 6:39 pm (6:20–7:00 pm)
- Likely visibility: poor. Swell (up to 9.0 ft at 8 s), rain (0.41 in) and wind over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 53.6 °F: a 7 mm semi-dry suit, with hood, gloves and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 5:52 pm. Waning gibbous (92%), rising at 5:52 pm: a bright night.
Your diving day at a glance
The best window, 12:30 pm to 1:20 pm, combines slack water at low tide and the sun high, though with a big swell, moderate wind and current.
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.

Moon phase and position
Today the moon is 226,451 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:03–3:03 am Major · the moon passes overhead · high activity
- 1:35–3:35 pm Major · the moon passes underfoot · high activity
- 10:42–11:42 am Minor · moonset · medium activity
- 5:22–6:22 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.

For fishing, swimming and diving
- Shore fishing. Very shallow: the water doesn't reach 16 ft within 1 mi. Cast far from the beach, ideally around high tide.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. Shallow: the water doesn't reach 33 ft within 1 mi. For deeper dives, take a boat farther out.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide. There is land ahead (an island, a headland or the far shore) 1 mi out.
