East Nusa Tenggara in December
Not the best time
December brings challenging weather that limits outdoor activities and makes travel logistics difficult. Only visit if you have flexible plans and don't mind spending considerable time indoors.
Weather
December ushers in the wet season proper with 14-15 rainy days and oppressive 82% humidity. Temperatures reach 31°C but feel much hotter due to moisture. Heavy downpours can last for hours, and rough seas often cancel boat trips.

All Months
April through September offers the sweet spot – dry skies, calm seas, and dragons basking in perfect weather. Peak season hits July and August when European families invade, driving up prices and crowding boat tours.
May and September provide the best balance of good weather and smaller crowds. April works too, but occasional rain showers linger from wet season. October through March brings heavy rains that cancel boat trips and turn roads into mud rivers.
Dry season also means better diving visibility around Komodo – you'll actually see the manta rays instead of murky water. But temperatures soar, especially on Sumba where shade becomes precious.
Book accommodations early for July and August. Many guesthouses close during rainy season, leaving fewer options when weather clears.
