Where this tide comes from
Grundarhverfi has no station of its own, so we use the tide at Reykjavík (TICON-4), 6.9 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.

The sea at Grundarhverfi
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.5 ft
- Significant3.0 ft
- Highest expectedHighest6.3 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 6.3 ft. Before heading out, expect waves of up to 6.3 ft.
Wind on the coast and offshore
Offshore wind. The coast faces west and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Saturday 31: 6.3 ft with a period of 9 s, from the west-southwest (moderate).
Water temperature

Surf in Grundarhverfi today
Surf today
Very good- 2.8–4.3 ft surf at the shore, a good size with some punch
- 3.3 ft swell at 12 s from the southwest, average
- Moderate offshore wind (13 mph): it holds up and grooms the waves
- Rising tide (high tide at 8:22 pm)
- Light: First light 8:09 am · sunrise 9:01 am · sunset 5:20 pm · last light 6:12 pm
- Tide: low 1:51 am (2.0 ft), high 7:59 am (14.8 ft), low 2:23 pm (2.5 ft) and high 8:22 pm (13.3 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.
- Water at 45.7 °F: a 6/5 hooded fullsuit with booties and gloves.
- Energy: 289 kJ · Medium power
Today’s surf at a glance
The best window, 4:00 pm to 6:00 pm, has a good size and light offshore wind. 1:00 pm to 3:00 pm also works, with a good size and light offshore wind.
An estimate for this stretch of coast, not for a specific break: every beach or reef works its own way (its tide, bottom and angle). Check it when you get there.
Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.
Diving in Grundarhverfi today
Diving and snorkeling today
Likely visibility: good- Slack water around low tide (2:23 pm): little current from 2:00 pm to 2:50 pm

- 0.1 mph current toward the south, weak (model)
- Sun high: more light underwater
- Slack water today: low tide 1:51 am (1:30–2:10 am), high tide 7:59 am (7:40–8:20 am), low tide 2:23 pm (2:00–2:50 pm) and high tide 8:22 pm (8:00–8:50 pm)
- Likely visibility: good. Swell (up to 3.7 ft) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 45.7 °F: a drysuit, with hood, gloves and booties.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 6:12 pm. Waning gibbous (85%): a bright night.
Your diving day at a glance
The best window, 1:40 pm to 3:10 pm, combines slack water at low tide, weak current and the sun high, though with moderate wind. Also worth a look from 10:30 am to 11:30 am, with light wind, weak current and the sun high, though with tidal 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.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 0.3 mi): cast far from the beach and fish the high tide, when there is more water close in.
- 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 near shore: you only reach 33 ft at 0.8 mi. For dives deeper than 33 ft, go by boat.
