# Benang Kelambu Upper Tier in September: Peaceful Forest Pool
September at Benang Kelambu upper tier delivers the year's best combination of conditions and accessibility. Peak dry-season pool clarity continues from July without weather degradation. The peak summer crowd surge has eased dramatically. Comfortable late-dry-season temperatures replace July's aggressive heat. The forest hike becomes genuinely pleasant rather than sweaty endurance.
If May is the second-best upper-tier month and July rewards heat-tolerance with refreshing swims, September is the unambiguous standout for overall experience quality.
Daytime highs at 28°C with overnight lows of 19°C. Humidity drops to 68% — the driest comfort of the year. Rainfall just 25mm across 2 days.
The September difference vs July:
Hike comfort: Forest temperatures of 25-27°C are pleasant rather than sweaty. The 30-45 minute climb feels like a walk rather than an effort.
Pool experience: Cooler air temperatures (28°C vs 30°C) make the cool pool less dramatically refreshing but more comfortable for extended swimming.
Sun angle: The September sun angle is moderating, making midday photography genuinely workable rather than harsh.
Trail conditions: Continued dry-season firmness. No mud or slippery sections.
Crowd math: Daily upper-tier visitors drop from July's 30-60 to September's 8-25. Most weekday visits have the pool essentially to yourself.
The September advantages compound:
Continued peak conditions: Same exceptional dry-season water flow and clarity as July
Comfortable temperatures: Pleasant for hiking and extended pool time
Crowd reduction: Most days the upper pool is essentially private
Easy logistics: Guide bookings, parking, all operations relaxed
Extended photography time: Tripod setup without crowd pressure
Multi-activity day support: Comfortable temperatures support full waterfall day with main + upper + Benang Stokel
Last dry-season window: October-November will have wet-season risks
September crowd level drops to 1 of 5 at the upper tier — the year-low. Typical pattern:
Weekday visits: 5-15 daily visitors. Often pool entirely empty for extended periods.
Weekend visits: 15-25 daily visitors. Comfortable spacing.
Maulid week (early September): Slight uptick from domestic visitors but still very quiet.
The crowd reduction enables genuinely unhurried visits:
Extended swim sessions: 60-90 minute pool time without time pressure
Photography setup: Tripod and ND filter setups without rushing
Quiet contemplation: The upper pool's natural silence is preserved
Family-friendly visits: Less crowd pressure makes it easier with children
September booking is genuinely flexible:

All three patterns work comfortably in September.
September light at the upper tier is exceptional:
Morning (09:00-11:00): Soft canopy-filtered light. Excellent for portraits and waterfall photography.
Mid-morning to early afternoon (11:00-14:00): Workable in September unlike July. Sun angle has moderated, light is bright but not harsh. Best for water-flow shots.
Late afternoon (14:00-16:00): Beautiful warm light. Reduced crowds allow extended setups.
Long-exposure water effects: 1-2 second exposures with ND filter create silky water look. September's calm crowd conditions allow tripod setups without rushed compositions.
Macro work: Forest understory and moss-covered rocks rich in macro subjects. September's quiet conditions allow careful slow exploration.
Underwater photography: Continued peak July visibility. Pool clarity excellent for swimmer-perspective shots.
September enables ambitious combinations:
Full waterfall day: Benang Kelambu main + upper + Benang Stokel. Genuinely comfortable in September temperatures.
Cultural + waterfall combination: Morning Banyumulek pottery + afternoon Benang Kelambu including upper tier. Comfortable pace.
Multi-day Aik Berik exploration: Stay at village base for 2 days, deep waterfall area exploration including upper tier and surrounding less-known waterfalls.
Combined with Sembalun: Benang Kelambu day on transit to Sembalun for Pergasingan camping. Comfortable September pace allows both.
September advantages over comparison months:
vs May: Drier, slightly cooler, lower crowds, easier guide booking.
vs July: Dramatically cooler hike, dramatically reduced crowds, still peak pool conditions, easier photography.
vs October: More reliable dry conditions (October starts wet-season transitions), continued peak pool clarity.
vs November: Vastly better in every dimension — dry vs wet, comfortable vs storm risk, beautiful vs cloud-obscured.
The September combination is the clear standout.
Three things to watch (less than peak-season months):
1. Maulid week: The week of September 4 (Maulid, Prophet's birthday) sees minor village staffing reductions as families participate in religious observances. Operations continue but with slight delays.
2. Late-September early-rain risk: The last week of September can see occasional afternoon showers. Mostly affects late-day visits; mornings remain reliably dry.
3. Forest mosquitoes: September forest has gradually increasing mosquito populations as wet-season prep begins. Apply repellent before the hike.
September upper tier visits make particular sense for:
The bar for "wrong month for September" is genuinely low. This is the recommended Benang Kelambu upper tier month for nearly all visitor types.
September is the standout month for Benang Kelambu upper tier visits. Continued peak dry-season pool clarity, dramatically reduced crowds (1 of 5 vs July's 3 of 5), comfortable hiking temperatures, easy logistics, and unhurried visit conditions combine to deliver the year's best upper-tier experience. For visitors with date flexibility, this is the unambiguous recommendation. Plan an extended 4-5 hour visit including main + upper + Benang Stokel for full appreciation.
September at Benang Kelambu upper tier offers the year's perfect waterfall photography conditions — comfortable hiking temperatures, continued peak dry-season water clarity, and dramatically reduced crowds that allow extended tripod setups without time pressure. The midday window (11:00-14:00) which becomes harsh in July's overhead sun delivers excellent September photography conditions because the sun angle has moderated. Bring a tripod and ND filter for slow-shutter water effects, and plan to spend 60-90 minutes at the upper tier alone for full exploration. The September upper-tier visit is genuinely one of Lombok's most peaceful waterfall experiences.
