Skip if you want a waterfall; do it if you want a quiet forest walk. The cascade is barely there in September.
Semeleng Waterfall in September is the quietest version of an already-quiet site. The cascade is reduced to a thin trickle as the catchment runs at its annual low, the pool is shallow, and the visit becomes more of a forest walk than a waterfall stop. Crowds drop to genuine zero on most days. Best treated as a slow nature walk with a small waterfall as turnaround point, or skipped in favour of higher-flow sites.
# Semeleng Waterfall in September: The Quietest Trickle
By September, Semeleng has eased into its quietest version of the year — and at a site that's already quiet, that means genuinely empty. The cascade has reduced to a thin trickle as the catchment runs at its annual low, the pool is shallow, and the visit becomes more of a forest walk than a waterfall stop. For travellers who can reframe the visit as a slow nature walk, September works. For travellers who expect a meaningful waterfall, it doesn't.
Two changes from July define the visit. The cascade weakens dramatically — what was a moderate cascade in July is now a thin curtain of water that you can see through to the rock face behind. The pool depth drops with the reduced inflow, and what was a modest 2-metre pool is now closer to 1 metre, more puddle than swim spot.
The forest itself remains pleasant. The trail is firm, leeches are absent, and the dry-season conditions make the walk in genuinely enjoyable. If you treat the visit as a forest walk with a small water feature at the end rather than as a waterfall stop, the September experience makes sense.
The honest assessment is that Semeleng in September isn't really a waterfall visit any more. The cascade is too small to be visually interesting, the pool isn't swimmable in any meaningful way, and the site lacks any other distinctive features (no deep emerald pool like Tibu Puyuh, no sacred significance like Mangku Sakti, no protected-forest setting like Timbangu).
What's left is the forest walk in and out. That's a 70-80 minute round trip walk through pleasant lowland East Lombok forest with a small water feature as the turnaround point. If you'd enjoy that walk on its own merits, September Semeleng is fine. If you came specifically for a waterfall, you'll feel disappointed.
Genuinely zero on most weekdays. September is the quietest month at Semeleng by some margin in a site that's already very quiet year-round. You can essentially count on having the trail and the falls entirely to yourself for the entire visit. Even the local Sasak from nearby villages skip Semeleng in September because the cascade isn't worth the walk.
This solitude is the September visit's main upside. If your priority is genuinely solo time in lowland Lombok forest, September Semeleng delivers that more reliably than any other month at any other site.
Off-peak rates:
Total for a couple: 130-230k IDR. The cheapest version of the Semeleng visit.
Reframe the visit as a forest walk:
The 30 minutes at the clearing is the actual experience. The cascade is just a small backdrop. Bring a book if you want — it's the kind of place where reading at a forest clearing for an hour makes sense.
If you have a meaningful interest in casual birding, the forest sections of the trail support several common species and September's dry conditions make spotting easier. Walk slowly, ideally with binoculars.
September is a good month for a slower East Lombok plan. The dry weather makes logistics simple, and visitor numbers everywhere are low. Semeleng works well as a contemplative end to a relaxed day, but only if you've adjusted your expectations.
A modified East Lombok plan that includes September Semeleng:
You can also do this as just two waterfalls (Timbangu and Tibu Puyuh) and skip Semeleng entirely. That's a perfectly reasonable choice in September.
Late September can show first hints of monsoon transition. Afternoon clouds build, occasional brief showers appear. None of this materially affects a Semeleng visit because the trail is short and forest cover protects from light rain, but pack a light shell. Early to mid September is the most reliable window.

It's wrong for travellers who:
For most travellers, the honest recommendation in September is to skip Semeleng entirely and do Timbangu plus Tibu Puyuh as a two-waterfall day. If you specifically want the third stop and the slow forest walk, Semeleng works — but go in with realistic expectations.
The cascade will be back in April. If you want the actual waterfall version of this site, wait.
September at Semeleng requires reframing the visit entirely. The cascade isn't really there — it's a thin trickle of water rather than a meaningful waterfall — and the pool is too shallow for proper swimming. So treat the visit as a slow 2-hour forest walk with a small water feature at the turnaround, not as a waterfall trip. The forest sections are pleasant in September's dry conditions, you'll see no other visitors, and the silence is genuinely meaningful. If you can accept that framing, Semeleng in September is worth doing as part of a slow-paced East Lombok day. If you're expecting a waterfall, you'll be disappointed.
