The shoulder begins. Genuinely usable for day trips and overnight stays for the first time since November.
March is the transition month — rainfall drops to 220mm across 16 days and boat crossings become reliable enough that day trips become feasible again. Snorkel visibility climbs to 12-18m. Crowds remain very low. Bau Nyale festival (south coast, late February or early March 2026) doesn't affect Gili Nanggu but does pull operators south. End of Ramadan (Mar 19) brings a slight Indonesian travel resumption.
# Gili Nanggu in March: The Wet Season Tail
March is the month wet season finally loosens its grip on the Secret Gilis. Rainfall drops by a third compared to February (from 280mm to 220mm), rainy days fall to 16, and boat crossings become predictable enough to plan around. This is when day trips re-enter the realm of "reliable" rather than "lottery."
Three things change in March that matter:
Boat reliability: Cancellation rates fall to 15-20% from February's 25-35%. Mornings are nearly always go-able. Afternoons are still subject to squalls but the daily wind cycle is less aggressive.
Visibility: Underwater clarity climbs to 12-18m as river runoff slows. The fish-feeding jetty looks excellent. The broader reef circuit becomes worth doing rather than disappointing.
Daylight wet windows: Rain in March tends to come in clear, contained afternoon storms (1-2 hours) rather than all-day greyness. You get genuinely sunny mornings, dramatic afternoon downpours, and clearing evenings.
This rhythm makes March one of the most photogenic months despite the technical "wet season" label.
Crowd level is barely above January-February. Most days you'll see 15-30 day-trippers on Gili Nanggu. The fish-feeding jetty might have a brief queue at midday but otherwise feels uncrowded.
The exception is the very end of the month around Eid al-Fitr (Mar 20-21, 2026). Indonesian families travel heavily for Eid, but most go inland to family villages rather than to tourist islands. Gili Nanggu sees a small bump but nothing dramatic. The bigger Eid effect is on Sekotong's mainland roads — heavy traffic for several days makes ground transport from Mataram or Senggigi slow.
Ramadan continues through Mar 19. Practical implications:
If you visit early-to-mid March, expect the same Ramadan considerations as February. After Mar 20 the mainland comes alive again.
Pricing remains in low-season territory:
Compared to peak season (July-August) where the same package could double, March is genuinely cheap.
Here's a March day trip that has high success odds:
7:30am: Arrive Sekotong Tawun beach. Charter or shared boat departure.
8:00am: Land Gili Nanggu. Walk the perimeter (20 minutes).
9:00am: Snorkel session at the fish-feeding jetty.
10:30am: Boat to Gili Sudak (5 minutes) for second snorkel spot.
11:30am: Return to Nanggu for lunch at the cottages.
1:00pm: Hammock or beach reading (often before any afternoon storm).
2:30pm: Boat back to Sekotong Tawun.
3:00pm: Mainland — usually before any storm front lands.
This works because it front-loads activity into the calm morning window and gets you back to the mainland before the typical 3-5pm squall window.
Staying overnight at Nanggu Cottages in March is genuinely comfortable. Generator hours are normal. Restaurant operates all meals. WiFi runs (slowly) most evenings. The covered platforms are still useful for the occasional all-day rain but most evenings are clear enough to enjoy beach time.
Star visibility on clear March nights is excellent — no light pollution, and the rainy-season air clarity (when it's not raining) is sharper than dry-season haze.
March Gili Nanggu suits:
March is wrong for:
For most international visitors looking for the "best value" Gili Nanggu trip, mid-March is the smartest single window in the entire year. Quality is most of the way up, prices are still all the way down.
Book mid-March (Mar 10-18) for the sweet spot: late wet season weather windows are widening, Ramadan keeps mainland quiet so prices stay low, and Eid travel hasn't kicked in yet. Avoid the Eid week (Mar 19-25) entirely on the mainland routes — Sekotong roads jam with returning families.
