The best time to visit Labuan Bajo for your plans
The best time to visit Labuan Bajo for lower rainfall is generally May to October, based on the historical climate pattern for Manggarai Barat district. That is a starting point for choosing dates, rather than a promise of calm seas. Wind, waves and currents remain separate considerations for a national park journey or a snorkelling stop.
Choose the activity first, then use the climate pattern to compare dates. A waterfront visit, an inland excursion and a full day on the water each respond differently to weather. The town and Flores sightseeing guide offers land-based choices, while the Komodo trip guide explains the island journeys whose routes depend on sea conditions.
Monthly rainfall in Manggarai Barat, 1991 to 2020
Manggarai Barat's monthly rainfall values are historical district averages from the BMKG normal atlas for 1991 to 2020. The atlas has a foreword dated 4 January 2022. These values describe the wider district, rather than a weather station in Labuan Bajo, a particular national park island or conditions on your travel day.
The district pattern places the lowest monthly value in August and higher totals from November to April. Use the figures to understand the broad change through the year. A month with a lower average still needs a current forecast, and the rainfall table should not be read as a prediction of the number of usable boat days.
| Month | District rainfall |
|---|---|
| January | 290 mm |
| February | 280 mm |
| March | 245 mm |
| April | 177 mm |
| May | 88 mm |
| June | 65 mm |
| July | 33 mm |
| August | 30 mm |
| September | 40 mm |
| October | 77 mm |
| November | 169 mm |
| December | 261 mm |
BMKG gives an annual district value of 1,755 mm for this historical normal period. Keep that figure attached to the same geographical area and period as the monthly table. Use current Labuan Bajo weather information for departure decisions, rather than treating historical rainfall as a live operating bulletin.
A boat day to plan around the season

A weather-dependent snorkelling day
A shared fast-boat journey from Labuan Bajo includes snorkelling equipment and stops at Taka Makassar, Manta Point and Kanawa, subject to conditions on the day.
Lower-rainfall months and boat planning
Labuan Bajo boat planning needs current conditions even during the lower-rainfall months of May to October. A day trip returns to a land base, while a liveaboard uses nights at sea. Compare those formats in the overnight sailing guide before deciding how much of the itinerary to commit to the water.
For Padar, prepare for exposed sections with drinking water, sun protection and a head covering. An early visit still needs the appropriate booked slot; choosing a particular month does not establish sunrise access. The hiking guide separates the island climb from the Flores trek and explains the relevant planning questions.
Manta observations as operator experience
Komodo manta observations occur throughout the year according to local operator experience, with September to May described as a period of larger numbers. Treat that as an account of wildlife encounters rather than a fixed official season. A Manta Point stop offers the opportunity to look for animals, with the outcome depending on the day.
The shared day journey includes a return fast boat from Labuan Bajo, stops at Taka Makassar, Manta Point and Kanawa, plus a mask, fins, snorkel and life jacket. Those inclusions support a snorkelling choice rather than a diving booking. The snorkelling guide covers equipment, water conditions and wildlife expectations in more detail.
Weather warnings and rebooking conditions
Labuan Bajo weather warnings must be matched to their validity period and the waters on the intended route. The BMKG harbour forecast dated 14 November 2026 is valid from 00:00 until 17 November 2026 at 00:00. A fresh forecast is needed after that period, and harbour conditions alone should not be extended to island passages or dive sites.
Separate the park reservation from the weather-related permission to sail. Discuss how a changed route, delayed departure or cancellation is handled under the terms of the particular booking. Rebooking and reimbursement depend on that agreement; organise flight connections and accommodation with the consequences of a changed sea itinerary in mind.
Questions about Labuan Bajo's seasons
Which months have lower rainfall?
May to October has lower rainfall in the historical Manggarai Barat district pattern for 1991 to 2020. August has the lowest monthly district value. Use that pattern when choosing dates, then use current marine weather for the actual outing, because lower rainfall alone does not settle waves, wind or currents.
Are the rainfall values measured only in Labuan Bajo?
No, the rainfall values cover Manggarai Barat district in BMKG's historical normal atlas for 1991 to 2020. They are district averages rather than a Labuan Bajo city-station series. The table helps compare the broad annual pattern and should remain separate from forecasts for a particular island or departure date.
Can a Manta Point visit guarantee manta sightings?
No, a Manta Point visit offers a wildlife observation opportunity rather than a guaranteed encounter. Operators report observations throughout the year and describe September to May as a period of larger numbers. Choose the trip for its snorkelling programme as a whole, with the final stops guided by sea conditions.
