Bonthe has no bridge and no fixed timetable — the way on and off Sherbro Island is a boat across open water. This page reads the wind and waves on the Yargoi crossing for today and tomorrow, in plain words, so you have some idea what the water is doing before you walk to the wharf.
On the water — Bonthe ↔ Yargoi
Right now: slight seas (waves around 0.6 m), light air (about 3 km/h, gusts to 13).

The crossing, normally
Departures follow the tide and the load, not the clock: boats leave when the water and the number of passengers allow. The times above are the pattern people report, not a promise.
The usual pattern
One wooden passenger boat (a "pam-pam", about 30 seats) a day each way: out of Bonthe around 8am, back from Yargoi around 4pm, roughly 2 hours on the water.
The other route
From Mattru Jong, the regular transport boat comes down the Jong River to Bonthe — most travellers overnight in Mattru Jong first.
Where to ask
At the wharf, or listen to Radio Bontico 96.9 FM. There is no published boat schedule anywhere — this page can read the water, not the boatmen's plans.
This water has taken lives
In January 2023, eleven people drowned in Bonthe District when an overloaded market boat capsized in heavy waves — a vessel that had been suspended for failing safety checks and was operating anyway.
Travel on registered vessels, let the Sierra Leone Maritime Administration staff record your name at departure, and wear the lifejacket if one is offered. If a boatman or the Maritime Administration says the water is not right, believe them.
Nothing on this page is a green light. The decision to cross belongs to the people at the wharf who can see the water — the Sierra Leone Maritime Administration is the authority on which vessels may sail.
Forecast updated 12 October at 11:51 am. Wave and wind figures are open-water model forecasts for the open water of the Sherbro estuary, on the Yargoi crossing, not readings from a boat — conditions in channels and near the shore differ. The words follow two published descriptive scales (the Douglas sea scale for waves, the Beaufort scale for wind); they describe the water and are never a judgement that a crossing is safe to make.
