Where this tide comes from

B · Nearby station

Prothrapur has no station of its own, so we use the tide at Port Blair (TICON-4), 5.3 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.

How we calculate the tide

Sea and waves

The sea at Prothrapur

Slight Douglas 3 · light air, Beaufort 1
Waves 1.7 ft · 6.1 s from the southwest (214°)

The waves you may find

  • Most commonMost common0.9 ft

  • Highest expectedHighest3.5 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.5 ft. Before heading out, expect waves of up to 3.5 ft.

Water warmer than normal for late October (+2.0 °F).

The best window, 5:00 am to 9:00 am, has glassy water, though with barely any waves.

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.

Your diving day at a glance

The best window, 9:40 am to 11:30 am, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also good from 3:50 pm to 4:50 pm, with slack water at low tide, little swell, light wind and weak 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
  • 12:28–2:28 am Major · the moon passes overhead · high activity
  • 1:00–3:00 pm Major · the moon passes underfoot · high activity
  • 7:39–8:39 am Minor · moonset · medium activity
  • 7:21–8:21 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.

Water depth

Gentle slope

The bottom slopes gently: 16 ft deep 0.3 mi from shore and 33 ft at 0.35 mi. It reaches 164 ft at 1.3 mi.

From the shoreline (1.9 mi from Prothrapur) out to sea, heading east.

How far from shore

  • 16 ft deep0.3 mi
  • 33 ft deep0.35 mi
  • 66 ft deep0.5 mi
  • 164 ft deep1.3 mi

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. Shore diving works here: 33 ft at 0.35 mi and 66 ft at 0.5 mi from shore.

Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).

Source: NOAA ETOPO 2022 (CC0), cells of about 0.3 mi; depth below mean sea level. For reference only: not for navigation or anchoring.
