Where this tide comes from
Easton has no station of its own, so we use the tide at West Bay Harbour (TICON-4), 18 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 Easton
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.5 ft
- Significant3.1 ft
- Highest expectedHighest6.2 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 6.2 ft. Before heading out, expect waves of up to 6.2 ft.
Wind on the coast and offshore
Onshore wind. The coast faces south and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Wednesday 4: 4.1 ft with a period of 5 s, from the east (slight).
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 58.9 °F by Wednesday 4.

Surf in Easton today
Surf today
Fair- 2.0–3.1 ft surf at the shore, a fun size for most surfers
- 2.8 ft swell at 7 s from the west-southwest, short: weak, messy waves
- Almost no wind (4 mph): glassy water
- Rising tide (high tide at 8:15 am)
- Light: First light 6:22 am · sunrise 6:56 am · sunset 4:51 pm · last light 5:25 pm
- Tide: low 1:23 am (1.7 ft), high 8:15 am (13.9 ft), low 1:43 pm (2.0 ft) and high 8:40 pm (13.1 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 59.9 °F: a 4/3 fullsuit.
- Energy: 79 kJ · Low power
Today’s surf at a glance
The best window, 7:00 am to 8:00 am, has a good size and glassy water, though with a short-period swell.
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 Easton today
Diving and snorkeling today
Likely visibility: fair- Tidal current running: mid-tide, the water is moving
- 2.4 ft swell at 8 s from the west-southwest: some surge on the bottom
- Light onshore wind (10 mph)

- Likely visibility: fair. Swell (up to 5.2 ft at 8 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 59.9 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 5:25 pm. Waning gibbous (85%), rising at 6:39 pm: a bright night.
Your diving day at a glance
The best window, 11:30 am to 12:30 pm, combines light wind and the sun high, though with tidal current 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.

Solunar periods
Today's activity: medium- 1:35–3:35 am Major · the moon passes overhead · high activity

- 11:06 am–12:06 pm Minor · moonset · 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 950 ft): 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 0.35 mi from shore; 66 ft is far out (1 mi): for deeper dives, go by boat.
