The honest answer is that there is no bad month. The Togeans sit almost on the equator, the water stays between 28 and 30 °C all year, and we dive and snorkel every month.
What changes is the sea between the islands — and that is what decides how comfortable your boat days are.
March to November: the calmest seas
This is the stretch we point people towards. Diving runs all year round, but the calmest seas are from March to November, and that matters less for the reef itself than for the crossings: the transfer from Luwuk, the day trip to the jellyfish lake, the run out to Una-Una.
Visibility sits in its usual 20 to 30 metre range and is at its best on the outer reefs.
The rest of the year
Outside that window the reef does not change and the water does not cool down. The sea simply gets more of a say in the day's plan.
Trips still run, but the order of the week is more likely to shift around the weather — which, on an island where nothing is scheduled to the minute, is easier than it sounds.
What you actually need to pack
A shorty or a 3 mm wetsuit is plenty at 28–30 °C. Closed shoes if you plan to walk the jungle trail to Malenge Village — the ground is uneven and often damp.
And less than you think of everything else: masks, snorkels, fins and life jackets are free for every guest, so there is no reason to carry your own set unless you are attached to it.
Pick the boats before the flights
The real constraint on your dates is not the season, it is the connections. The ferry from Gorontalo sails on Tuesday and Friday; the public boat from Ampana to Malenge runs Monday, Wednesday and Saturday; only the Luwuk pick-up runs every day of the week.
Choose the route first and the dates tend to fall into place around it.
