Genuinely excellent. The first month of the year worth recommending without reservations.
April is when the dry season takes hold. Rain drops to 130mm across 10 days, boats run reliably, and snorkel visibility climbs to 15-20m. Crowds remain low (under 50/day most days). Easter typically draws Australian families but Gili Nanggu is too remote to feel the impact strongly. This is the start of the genuine sweet spot — quality climbing fast while prices stay near low-season.
# Gili Nanggu in April: The Sweet Spot Opens
April is the month Gili Nanggu transitions from "weather-dependent gamble" to "reliable, beautiful, quiet." Rainfall drops by 40% from March (220mm to 130mm), rainy days fall to 10, and the daily rain pattern shifts from afternoon storms to brief passing showers. The Lombok Strait calms.
This is when serious snorkelers, photographers, and quiet-seeking travelers should pay attention.
Three big shifts:
Visibility climbs: Underwater clarity reaches 15-20m, approaching dry-season peak. Coral colors return to vibrant. The fish-feeding jetty is at its most photogenic.
Boats become a non-issue: Crossing reliability hits 90%+. The Sekotong Tawun departure point operates normal hours. Public shared boats run daily. Charter prices stabilize.
Trade winds start whispering: Light easterly trade winds begin, cooling evenings and reducing humidity. Daytime temperatures stay warm (32°C high) but the muggy quality of February-March recedes.
April is still genuinely uncrowded. Most days see 30-50 visitors total. Weekends bump higher with Lombok-resident day-trippers from Mataram and Senggigi.
Easter weekend (April 3-5, 2026) brings a small Australian family contingent, mostly to the main Gili Trio (Trawangan, Air, Meno) rather than the Secret Gilis. Gili Nanggu feels the spillover only marginally — maybe 60-80 visitors on the Easter Saturday peak.
Australian school holidays in mid-April are a bigger factor for Gili Trawangan than for Sekotong's Secret Gilis. Nanggu remains under-the-radar.
April is officially shoulder season. Pricing reflects that:
A two-person day trip including charter, gear, and lunch lands around 800k-1m IDR — still significantly cheaper than July's 1.4m+.
If you want a tight-budget April trip, target either the first week (April 1-5, before Easter weekend bumps) or the last week (April 26-30, after Australian school holidays end). Mid-month is fine but slightly pricier.
For overnight stays, weekday Sunday-Thursday at Nanggu Cottages stays in the 700-850k IDR range. Weekend Friday-Saturday creeps to 950k-1.0m as Lombok residents book getaways.
April snorkeling is finally good. The fish-feeding area near the jetty has 15-18m visibility on most mornings. The broader reef circuit (extending toward Gili Sudak and Gili Kedis) opens up to genuine 4-island day trips that operators can deliver on.
Common species visible:
The water temperature sits around 27-28°C, comfortable for extended sessions without thermal protection.
Light easterly trade winds begin in April. Practical effects:
The wind also helps with the occasional brief afternoon shower — they pass quickly rather than lingering.
April is the first month where overnight stays on Nanggu Cottages become genuinely worth recommending. Reasons to stay overnight:

April is wrong for:
For first-time visitors to the Secret Gilis cluster, April is among the best three months to visit — comparable to May and rivaling October. The combination of reliable conditions, low crowds, and not-yet-peak prices makes it a genuine sweet spot.
April is the secret value month. Conditions are 90% as good as peak July-August but day-trip charters are still 20-25% cheaper and overnight rooms haven't reverted to high season pricing yet. Book the second-to-last week (Apr 20-26) when Easter has passed and Australian families have gone home.
