Where this tide comes from
Flexbury has no station of its own, so we use the tide at Port Isaac (TICON-4), 21 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 Flexbury
Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.5 ft
- Significant7.0 ft
- Highest expectedHighest14 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 14 ft. Before heading out, expect waves of up to 14 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 ease over the next few days. The biggest waves arrive on Wednesday 28: 12 ft with a period of 11 s, from the west (rough).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water cools over the next few days: about 58.0 °F by Tuesday 3.
Water warmer than normal for late October (+1.2 °F).

Surf in Flexbury today
Surf today
Poor- 5.7–8.8 ft surf at the shore, big
- Big surf (8.8 ft): for experienced surfers
- 8.4 ft swell at 9 s from the west, a bit short
- Light onshore wind (12 mph): a bit of chop
- Rising tide (high tide at 6:38 pm)
Big surf: for experienced surfers only. If in doubt, stay on the beach.
- Light: First light 6:29 am · sunrise 7:03 am · sunset 5:00 pm · last light 5:34 pm
- Tide: low 12:12 am (2.6 ft), high 6:14 am (26.0 ft), low 12:33 pm (2.9 ft) and high 6:38 pm (25.8 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 58.8 °F: a 4/3 fullsuit (booties if you run cold).

Today’s surf at a glance
The best window, 4:00 pm to 5:34 pm, has a good size, though with big surf and onshore wind. 2:00 pm to 3:00 pm can also work, with a good size, though with big surf and onshore 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 Flexbury today
Diving and snorkeling today
Likely visibility: poor- Slack water around low tide (12:33 pm): little current from 12:10 pm to 1:00 pm
- 8.9 ft swell at 9 s from the west: heavy surge on the bottom
- Moderate onshore wind (16 mph)
- 0.2 mph current toward the south-southeast, weak (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 12:12 am (11:50 pm–12:30 am), high tide 6:14 am (5:59–6:30 am), low tide 12:33 pm (12:10–1:00 pm) and high tide 6:38 pm (6:20–7:00 pm)
- Likely visibility: poor. Swell (up to 11 ft at 10 s) and wind over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 58.8 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 5:34 pm. Waning gibbous (92%), rising at 5:49 pm: a bright night.
Your diving day at a glance
The best window, 12:00 pm to 1:30 pm, combines slack water at low tide, weak current and the sun high, though with a big swell and moderate wind.
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- 12:41–2:41 am Major · the moon passes overhead · high activity
- 1:12–3:12 pm Major · the moon passes underfoot · high activity
- 10:00–11:00 am Minor · moonset · medium activity
- 5:19–6:19 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. Shallow, gradual bottom (16 ft at 0.4 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. 33 ft deep 0.6 mi from shore; 66 ft is far out (1.2 mi): for deeper dives, go by boat.
