The Pig Island fleet works mornings. Boats leave the south coast between roughly
half past eight and half past nine, the beach at Koh Madsum fills up between ten
and midday, and by early afternoon almost all of them are back at the pier. An
afternoon departure walks into the space they leave behind.
That is the entire argument, and it is a strong one. The pigs do not go anywhere.
The reef at Koh Tan does not change. What changes is how many other people are
standing on a small crescent of sand with you, and how the light falls on all of
it. Midday sun over shallow turquoise water is unflattering in a way that is
difficult to photograph around; late afternoon is the opposite problem, which is
to say no problem at all.
What the afternoon trades away
Two things, honestly.
Flatter water is usually a morning phenomenon in the Gulf. Wind tends to build
through the day, so an afternoon crossing can be bumpier than the same route at
nine in the morning, and the kayaking is the first casualty — low tide, big waves
or strong wind and it is cancelled outright while the rest of the trip runs.
The pigs are also more active earlier. They come down to the water line when boats
arrive and they are at their liveliest before the heat sets in. By late afternoon
they are often exactly where you would expect a pig to be at the end of a hot day,
which is lying in the shade. Whether that is a loss depends on what you came for.
The dinner is not a garnish
On the trip featured here, dinner is a full Thai set menu at the operator’s own
restaurant back on the mainland, and it is part of the ticket rather than an
upsell. Water and soft drinks are included; alcohol is not. There is a vegetarian
option if you flag it when booking.
This trip is also one of the few in the whole catalogue that includes the 50-baht
Koh Madsum landing fee, so it is one of the few where you do not need to arrive
with cash for it.
Morning if you have one day, afternoon if you have several
That is the short version. A single free day on Koh Samui with uncertain weather
argues for a morning boat: calmer water, more margin if something needs
rescheduling, and the afternoon still free. Several days, or a return visit, and
the afternoon slot is the better experience by a distance.
