Surf in Kampung Teluk Air Tawar 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 4 s from the west-northwest, short: weak, messy waves
- Light offshore wind (6 mph): it holds up and grooms the waves
- Falling tide (low tide at 9:17 am)
- Light: First light 6:43 am · sunrise 7:04 am · sunset 7:00 pm · last light 7:22 pm
- Tide: high 2:13 am (9.5 ft), low 9:17 am (1.8 ft), high 2:47 pm (7.9 ft) and low 9:09 pm (3.1 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 87.1 °F–88.0 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 8 kJ · Low power
Today’s surf at a glance
The best window, 7:00 am to 10:00 am, has light offshore wind, though with a short-period swell. 12:00 pm to 4:00 pm can also work, with glassy water, though with small waves and 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.

- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 7:22 pm. Waning gibbous (88%), rising at 10:03 pm: a bright night.
Your diving day at a glance
The best window, 2:00 pm to 4:00 pm, combines slack water at high tide, little swell, light wind and the sun high, though with current. Also worth a look from 5:00 pm to 6:30 pm, with little swell, light wind and weak current, 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 2.7 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: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
