Marginally better than January but still wet-season territory. Worth it only if you accept the weather gamble.
February is the second-wettest month on Gili Nanggu with 280mm rain across 20 days. Boat reliability improves marginally over January but cancellation rate is still 25-35%. Snorkel visibility climbs slightly to 10-15m. Chinese New Year (Feb 17, 2026) brings a small bump in regional day-trippers but nothing close to crowded. Defensible if you have flexibility, skippable if snorkeling is the goal.
# Gili Nanggu in February: A Slightly Drier Wet Season
February is technically still wet season for the Secret Gilis cluster, but it's a step up from January. Rainfall drops from 320mm to 280mm and rainy days fall from 22 to 20. The improvement is real but small. Don't expect dry-season magic.
Sekotong Tawun to Gili Nanggu crossings remain weather-dependent. Cancellation rate sits at roughly 25-35% in February — better than January's 30-40% but still high enough that you should plan flex days.
Morning crossings (7-10am) are the most reliable window. The sea state is calmest before the daily heating cycle kicks up afternoon winds and squalls. By 11am most days, conditions deteriorate. By 2pm, return crossings get cancelled often.
If you're day-tripping, commit to the first morning boat and the first available return. Don't try to maximize island time by lingering for a late afternoon return — you'll get stranded.
Visibility climbs from January's 8-12m to a more respectable 10-15m in February. Still well below dry-season peak (20m+) but enough that the fish-feeding area near the jetty looks vibrant again.
The reef circuit broader than the jetty zone remains muted. February runoff from Lombok's southwest rivers still carries sediment into the Sekotong Bay. Don't expect the dazzling clarity dive videos show — those are filmed September through November.
If snorkeling is acceptable rather than transcendent, February works. If snorkeling is the trip's main reason, wait.
Chinese New Year falls on February 17, 2026. The week around it (Feb 14-22) sees a small bump in regional Asian day-trippers — Singaporeans, Malaysians, mainland Chinese travelers extending Bali trips with a Lombok side journey.
This isn't crowding by Western standards. You might see 30-50 day-trippers on peak CNY days versus the usual 10-20. The fish-feeding jetty has a queue. Boats run more reliably because demand justifies it.
After Feb 22, numbers drop back to baseline — and after Ramadan begins Feb 18, drop further still.
The Islamic holy month of Ramadan starts February 18, 2026 and runs until March 19. For Gili Nanggu specifically:
This isn't a problem for visiting Gili Nanggu — services continue — but be aware that the surrounding mainland will feel notably subdued. Pack snacks for daytime.
Room availability is wide open. Discounts hold steady at 20-30% off peak rates (600-800k IDR for the standard cottages). Staff have time for service. Restaurant operates with limited daily menu.
The covered platforms remain perfect rainy-afternoon refuges. Bring books and offline downloads. WiFi is technically present but slow.
Hot water and freshwater showers function normally — February runoff actually keeps the island's freshwater situation comfortable, unlike late dry season when supplies tighten.
Boat charter for 4-island circuit: 350-400k IDR (slight increase from January).
Public shared boat: 50k IDR per direction, runs more often than January but still not daily.
Snorkel gear rental on island: 50k IDR/day.
Lunch at Nanggu Cottages restaurant: 80-150k IDR per dish.
Total day-trip budget for two people including charter, gear, and lunch: roughly 700-900k IDR.
February Gili Nanggu suits:
February is wrong for:
The honest answer for most travelers asking about February: come back in April when the rain backs off significantly, or wait for September-October when visibility peaks.
Book your Sekotong Tawun crossing for the 7:30-8:30am window. February mornings have a 1-2 hour calm window before the daily wind cycle starts. Once Ramadan begins on Feb 18, ferry boatmen who fast may slow down or skip afternoon trips entirely — confirm return arrangements before crossing.
