Where this tide comes from
St Austell has no station of its own, so we use the tide at Port Isaac (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 St Austell
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.3 ft
- Significant2.5 ft
- Highest expectedHighest5.1 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.1 ft. Before heading out, expect waves of up to 5.1 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces southeast 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 build over the next few days. The biggest waves arrive on Wednesday 4: 4.1 ft with a period of 5 s, from the east-southeast (moderate).
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.

Surf in St Austell today
Surf today
Poor- 1.1–1.7 ft surf at the shore, small: good for learning or a longboard
- 1.6 ft swell at 7 s from the southwest, short: weak, messy waves; it hits this coast at an angle
- Almost no wind (3 mph): glassy water
- Falling tide (low tide at 1:17 pm)
- Light: First light 6:31 am · sunrise 7:04 am · sunset 5:00 pm · last light 5:34 pm
- Tide: low 12:53 am (3.3 ft), high 6:56 am (25.4 ft), low 1:17 pm (3.7 ft) and high 7:22 pm (24.8 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 58.3 °F: a 4/3 fullsuit (booties if you run cold).
- Energy: 23 kJ · Low power
Today’s surf at a glance
The best window, 7:00 am to 9:00 am, has glassy water, though with a short-period swell. 10:00 am to 2:00 pm can also work, though with a short-period swell, wind swell 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 St Austell today

- Likely visibility: good. Swell (up to 3.4 ft at 9 s) over the last few days has stirred up the water. Based on the last 24 hours of data.

- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 5:34 pm. Waning gibbous (85%), rising at 6:50 pm: a bright night.
Your diving day at a glance
The best window, 7:00 am to 7:50 am, combines slack water at high tide, light wind and weak current. Also worth a look from 12:30 pm to 2:00 pm, with slack water at low tide, weak current and the sun high, though with 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.

Solunar periods
Today's activity: medium- 1:45–3:45 am Major · the moon passes overhead · high activity
- 2:18–4:18 pm Major · the moon passes underfoot · high activity
- 11:14 am–12:14 pm Minor · moonset · medium activity
- 6:20–7:20 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 0.3 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. 33 ft deep 0.6 mi from shore; 66 ft is far out (2.2 mi): for deeper dives, go by boat.
