Seasonal Guide · Updated May 2026
With Komodo National Park’s new 1,000-visitor daily cap reshaping the 2026 travel calendar, May and June have emerged as the sweet-spot months — calm seas, 25m+ underwater visibility, manta rays at peak feeding, and crowd levels 40% lower than July–August peak. This guide breaks down exactly when to book your Komodo trip in May vs June 2026, with data from our Labuan Bajo operations team.
The Quick Answer — May vs June 2026
Choose May 2026 if: you want manta rays at peak abundance, the absolute calmest seas (sea state 1–2 of 5), and 30–40% fewer boats at Padar Island. Best for first-time visitors, honeymooners, photographers.
Choose June 2026 if: you want warmer water for snorkeling (28–29°C vs May’s 26–27°C), longer daylight hours (sunrise 6:00 vs 5:55), and you’re combining your Komodo trip with Bali or Lombok before peak July season hits. Best for divers, families, multi-island travelers.

May 2026 — The Manta Sweet Spot
May sits at the perfect threshold between wet season tail (ending late April) and full dry season (June onward). The water is clear, the plankton bloom from the wet season is still bringing manta rays to feeding stations at Manta Point, and most boats run at 70% capacity rather than peak’s 95%. May 2026 has the additional advantage of the 1,000-visitor cap being newly enforced — operators are still adjusting their booking systems, meaning quota availability is more flexible than peak months.
Best for May trips: Romantic honeymoon charters, photography expeditions, manta-focused snorkel tours.
June 2026 — The Diving Sweet Spot
June 2026 brings warmer water (28–29°C — bath-like), longer daylight, drier conditions, and the beginning of southeast trade winds that improve visibility on the south-facing dive sites. Castle Rock, Crystal Rock, and Cauldron all see 25–28m visibility. Dragon activity peaks in late afternoon as temperatures drop, making 16:00–17:30 the best ranger trek window. Komodo diving guide.
Best for June trips: Diving liveaboards, family trips, multi-island itineraries (Bali + Komodo or Lombok + Komodo).
How the 2026 Quota Changes the May vs June Decision
Before April 2026: choosing May vs June was mostly about weather. After April 2026: the SiOra reservation system caps daily visitors at 1,000 — Padar Island, Komodo Island, and Rinca each get their own sub-quota. June 2026 sees stronger demand (school holidays in Europe starting), so quota fills 4–6 weeks ahead. May 2026 quota typically still available 2–3 weeks ahead.
If you’re a flexible date traveler chasing the BEST combination of weather + uncrowded + affordable, book the last two weeks of May 2026. Best value all year.
