April is the official start of Lombok's dry season. Rainfall drops to 110mm across 9 days, Mount Rinjani trekking gates reopen around April 1, and dive visibility climbs to 20–25m. Prices remain in shoulder territory (about 20% below July peak), making April one of the year's strongest value windows.
# Lombok in April: The Dry Season Opens
April is when Lombok turns the corner. The wet pattern dissolves in the first week, the southeast trade winds begin establishing themselves, and Mount Rinjani's trekking gates reopen for the first time in three months. For travellers who want dry-season conditions without peak-season prices and crowds, April is one of the strongest months on the calendar.
Daytime highs around 32°C, overnight lows around 24°C, humidity dropping to 78%. Rainfall totals 110mm across about 9 days — roughly 60% of March's total, and the lowest of any month outside the deep dry season. Most rain falls as brief afternoon showers rather than the prolonged thunderstorms of January and February.
Sea conditions are excellent. Dive and snorkel visibility climbs from 20m at the start of the month to 25m by month-end. Sea temperature stays a warm 28°C. Wind picks up gradually as southeast trades establish, but stays moderate compared to peak season.
The light changes dramatically. Sunsets become reliable again, golden hour returns, and you can plan dawn-to-dusk itineraries with high confidence of cooperating weather.
Mount Rinjani reopens: Trekking gates at Sembalun and Senaru reopen approximately April 1 each year. The first two weeks see limited operator availability as guides return and trail repairs complete; bookings get easier from mid-April. Conditions on the mountain itself are still wet — expect mud and the occasional storm — but the trek is officially possible.
Easter weekend: Easter 2026 falls April 5 (Easter Sunday April 5 in some calendars, varies by tradition). Foreign tourist arrivals bump for 4–5 days around the Easter weekend, with European and Australian families on school break. Gili Trawangan and Senggigi feel busier than the rest of the month.
Galungan: Balinese Hindu festival on April 22, 2026. Hindu communities in Cakranegara and west Lombok decorate streets with penjor (bamboo poles). A culturally rich day for visitors interested in Hindu traditions; minimal disruption to tourism.
Diving: Operators move to full schedules. April is one of the most under-booked dive months despite delivering near-peak visibility.
Surf: Southeast trade winds strengthen, kicking off the south coast surf season. By late April, Gerupuk, Mawi, and Desert Point begin delivering consistent swells.
Mount Rinjani: First month of trekking after the closure. Book operators with strong recent reviews — some guides have been off-mountain for three months. Trails are clear by mid-April. Sembalun side stays drier than Senaru.
Kuta Lombok and the south coast: Surf consistency builds through the month. Selong Belanak, Mawi, and Gerupuk all reliable. South coast beaches are at their best — empty, sunny, swim-friendly.
Gili Islands: Excellent month. Visibility for snorkelling and diving climbs to 20–25m, sunsets are consistent, and crowds remain low except over Easter weekend.
Sembalun Valley: Best month to visit for landscape photography — green from late wet season, clear skies, dramatic Rinjani views.
Senggigi and west coast: Sunset cruises run reliably. Pleasant beach conditions, easy room negotiations.
About 20% below July peak across most of the month, with a small Easter bump:
The cheapest weeks are April 8–22 (post-Easter, pre-late-April surf bookings).
The standout window is April 10–22. Easter crowds have left, late-April surf bookings haven't arrived, Rinjani trails have dried out from the early-month mud, and dive visibility has climbed. Prices sit firmly in shoulder territory. You get most of the dry-season experience for 25% less than what June or July will cost. For Mount Rinjani specifically, this two-week window combines the lowest crowds of the open season with workable trail conditions — book operators with recent post-reopen reviews.
