November is the budget month here — cheapest charters, fewest visitors, but reduced visibility and storm-disrupted afternoons. Worth it for experienced snorkelers on a budget.
Bumbang Island in November is in early wet-season mode. Daytime temperatures hold around 32°C, but rainfall jumps to 180mm across 13 days and humidity climbs to 80%. Snorkel visibility on the surrounding reef drops to 8-15m, the boat crossing from Tanjung Luar gets choppier with variable wet-season winds, and afternoon storms force trips to morning windows only. Charter prices drop to year-low.
# Bumbang Island in November: Wet Season Begins
November is when Lombok turns. The dry-season trade winds collapse, the first real rains arrive, and the snorkel conditions at Bumbang Island drop from their July-September peak. The islet itself is still uninhabited and beautiful, the reef sharks are still around, and the prices drop to year-low. It's not the version of this trip you'd recommend to first-time snorkelers — but it works for budget travelers who can accept the trade-offs.
October sits at the dry-season tail with mostly clean conditions; by mid-November Lombok has crossed into the wet-season regime. The shifts:
For Bumbang Island trips specifically, these add up to a meaningfully different experience than dry-season months — lower-quality snorkel, more weather-disrupted plans, but lower prices and even fewer visitors.
The headline activity at Bumbang — snorkel sessions on the surrounding reef — still works in November but with lower visibility. Specifically:
For experienced snorkelers and divers, 10-15m visibility is still workable and the reef shark experience remains valuable. For first-time snorkelers expecting the postcard underwater clarity, November will disappoint — wait for next dry season.
The 30-45 minute crossing from Tanjung Luar is more variable in November:
The honest plan is morning departures only (6:30-7:30 AM) on days when no storm is forecast for the next 8 hours. Build flexibility into your schedule — be willing to reschedule a day if weather looks bad.
Charter prices are at year-low. Typical November rates:
Captains are happy for the work and very flexible. The catch is weather: morning windows are reliable on calm-forecast days, anything else is gambling.
November weather on east Lombok generally follows a daily pattern:
Boat trips work in the morning window. Plan to depart by 6:30 AM, return by 1-2 PM at the latest. Trying to extend into the afternoon risks getting caught on the water in a storm — uncomfortable at best, dangerous at worst.
The fishing port at Tanjung Luar continues to operate through November, though some captains shift toward inshore fishing and away from longer offshore trips during unsettled weather. The fish market still runs daily. The atmosphere is slightly slower than dry-season months.
For visitors, this means slightly more captain availability for charters but also more variable schedules. Confirm your booking the night before and reconfirm in the morning before driving to the harbor.
Even with the conditions trade-offs, November at Bumbang Island still delivers a meaningful experience:
For experienced snorkelers willing to trade peak clarity for low prices and complete solitude, this is genuinely a value month.
The dramatic stormy skies over the islet and surrounding sea are the visual highlight of November visits. When a system builds over the inland mountains and breaks across the Alas Strait around dusk, the light can be exceptional — torn cloud, rays cutting through, lightning over open water. From a safe spot in the boat or on the islet, the photography is more compelling than dry-season clear skies.
The catch is timing — you can't plan for the right storm-edge moment, and being on the boat during active storms is genuinely uncomfortable.
What is here on the islet: small beach, surrounding reef, your boat, your captain.
What is not here: any infrastructure, food, water, toilets, shelter, signal, rescue, weather guarantees.
Bring everything. Plan for weather-disrupted days. Tell your guesthouse where you're going.
Right for: budget travelers willing to accept reduced snorkel visibility for 30-40% lower prices; experienced snorkelers comfortable with 10-15m viz; travelers who value emptiness and authentic local interaction; storm photographers; anyone planning a multi-day east Lombok loop on a budget.
Wrong for: first-time snorkelers expecting peak conditions; visitors with no flexibility on weather; anyone needing reliable schedules; short-trip visitors who only have one chance to see Bumbang (come in dry season instead); families with young children.
If you have flexibility, save Bumbang Island for July or September. If you're already in east Lombok in November and want a budget snorkel adventure, this trip still works with realistic expectations.
November is when you can score the cheapest Bumbang Island charters of the year — 30-40% off dry-season rates — but only if you're willing to commit to morning departures and accept reduced visibility. Watch the weather carefully for a 24-hour calm-window day, book the night before, and depart at 6:30 AM to maximize your time on the reef before afternoon storms develop. The reef sharks are still around (they don't migrate), and even at 10m visibility you can see them clearly. For experienced snorkelers willing to trade peak clarity for low prices and zero crowds, this is genuinely a value month.
