Semidiurnal: two high and two low tides a day, of similar height.

The sea at Zanzibar
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.4 ft
- Significant0.9 ft
- Highest expectedHighest1.8 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.8 ft. Before heading out, expect waves of up to 1.8 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces northwest 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 stay much the same all week. The biggest waves arrive on Wednesday 28: 1.4 ft with a period of 4 s, from the southeast (smooth).
Water temperature

Today’s surf at a glance
The best window, 6:00 am to 10:00 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.
Diving in Zanzibar today
Diving and snorkeling today
Likely visibility: good- Slack water around low tide (11:18 am): little current from 11:00 am to 11:33 am

- Likely visibility: good. The sea has been calm and there's been little rain. Based on the last 24 hours of data.
- Water at 81.5–82.6 °F: a shorty or a rash guard.
- Snorkeling: good, calm sea and light wind.
- Night dive: dark from 6:38 pm. Waning gibbous (93%), rising at 8:39 pm: a bright night.
Your diving day at a glance
The best window, 10:40 am to 12:00 pm, combines slack water at low tide, little swell, light wind, weak current and the sun high. Also good from 4:50 pm to 6:20 pm, with slack water at high 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.
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 226,484 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 12:38–2:38 am Major · the moon passes overhead · high activity
- 1:09–3:09 pm Major · the moon passes underfoot · high activity
- 7:11–8:11 am Minor · moonset · medium activity
- 8:09–9:09 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

From the shoreline (0.6 mi from Zanzibar) out to sea, heading northwest.
How far from shore
- 16 ft deep550 ft
- 33 ft deep1,150 ft
- 66 ft deepnot within 3.1 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 7.2 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. 33 ft deep 1,150 ft from shore; 66 ft is far out (beyond 3.1 mi): for deeper dives, go by boat.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
