SWELLRADAR is requesting a verified marine run for Dirty Hippies.
Spot intelligence.
Dirty Hippies is the shallow Kertasari-area left, not Scar Reef farther south or the softer Middle Reef in the same bay. Advanced is a conservative minimum for independent recommendations across this slab and the unvalidated model band. Selected smaller-wave longboarding does not establish a safe learner range, risk-free channel or clearance for heavy surf.

Reviewed 23 Oct 2026 · not observation-validated
Published sources reviewed by SWELLRADAR, not validation against measured breaking waves. Swell and independently stated wind references are qualitative ranking inputs, not surveyed optima, measured shelter or full acceptance windows. The inherited generic 0.6–3.0 m offshore-model ranking band remains unchanged and unvalidated: not a measured local working range, safe learner range or wave-face conversion. Original approximate map pins and location sources remain. Explicit six-kilometre sea requests do not survey reefs, channels, currents, access or provider-snapped cells. SurfStories' first-person visits establish the steep left, thick lip, shallow reef and boulders. Mondo's local operator confirms the left but makes all-level suitability conditional on size/tide; its selected lessons do not override the exact-peak specialist guide's Advanced classification. Indonesian Surf Guide supplies S–SW swell and independent E–NE wind; 202.5 degrees is an explicitly coarse sector reference and E is one stated wind reference, not a calculated opposite. Nomad independently corroborates the hollow left and low-water warning. Regional tide-height anecdotes and energy thresholds are not adopted as transferable local calibration; no normalized tide bonus, preferred window, safe depth or empirical height factor is inferred.
- SurfStories · original first-person Dirty Hippies account
Repeated-visit account of the fast left, thick lip, shallow reef and boulders; channel wording is not a surveyed safe route and dated anecdotes are not current observations
- Indonesian Surf Guide · original Dirty Hippies listing
Advanced left slab, S–SW swell and independent E–NE wind sector, sharp reef and exit cautions; numeric guide sizes are not adopted as measured local limits
- Mondo Conservation · own local surf-break descriptions
Local operator independently identifies the left and explicitly conditions broader ability on swell and tide
- Nomad Surfers · original West Sumbawa guide
Separate Dirty Hippies paragraph corroborates short hollow lefts and shallow low-water reef, not the nearby Middles A-frame

Character
01Dirty Hippies is defined by left · short powerful barrel over shallow reef · boulders in the impact zone. The shape can change with swell angle, period and the active section, so the live score should always be paired with a visual check from shore.
Best setup
02S–SW · qualitative slab reference swell, e · reference within the guide's e–ne sector and shallow reef · check water cover locally form the profile baseline. SWELLRADAR retains 0.6–3.0 m as an offshore-model ranking band, not a measured local surf limit or a breaking-wave prediction.
Lineup read
03This is an advanced profile: positioning, entry and exit should be assessed before committing. Pay particular attention to shallow reef and impact-zone boulders, thick pitching lip, difficult exit on larger swell. Local signs and advice always take priority.

Data note
Model data unavailable
SWELLRADAR withholds numerical conditions, scores and surf windows until a quality-checked marine forecast is available.
