Spot guide

## The spot Cimaja is a consistent right-hand break in West Java, offering quality waves within a few hours' drive of Jakarta. The wave breaks over a stable platform of rounded river cobblestones and underlying coral reef, producing predictable, workable walls that peel along the rocky bank. The setting is lush tropical coastline backed by rice paddies and jungle. As the most accessible quality wave near Indonesia's capital, Cimaja has developed a dedicated local surf scene. ## When it works South-westerly Indian Ocean groundswells arrive consistently from April through October during the dry season. The wave activates on 3ft swells and handles up to 6-8ft before becoming too powerful for most surfers. North-easterly offshore winds are standard during the dry season, strongest in the mornings. The wet season brings onshore winds but swell still arrives intermittently. ## Where to sit The main take-off zone sits where the cobblestone point forces the swell to steepen. The right peels for 50-100 metres along the rocky bottom. Position yourself at the top of the point beside the most prominent rock formation. The wave walls up predictably, allowing a beat after the take-off before setting your line. The channel alongside the point provides the paddle-out. ## Hazards The cobblestone and reef bottom is uneven and falls can result in bruising or cuts. On bigger swells, the wave produces thick, powerful lips that demand confident navigation. Sea urchins inhabit the reef sections. Currents strengthen on bigger days. The drive from Jakarta involves narrow, congested roads that are hazardous. ## Parking and access Informal parking is available along the road above the break. The walk to the waterline is short. Basic warungs provide food and drink. Simple accommodation is available in the area. Cimaja is approximately 4 hours' drive from Jakarta via Pelabuhan Ratu. ## The crowd Cimaja draws Jakarta's surf community on weekends, producing moderate crowds of 15-25 surfers. Weekdays are significantly quieter with mostly local surfers. The atmosphere is friendly and the Javanese surf community is welcoming. The wave's length means there is room for everyone to spread along the point. ## Local tips The wave changes character with tide. Lower tides produce hollower, faster sections over the shallower reef. Higher tides make the wave fatter and more forgiving. Match your tide choice to your skill level. A standard shortboard works well. The drive from Jakarta is tiring; consider staying overnight in the area to maximise your surf time. Friday afternoon departures beat the Saturday morning traffic rush.

Frequently asked questions

How often is this page updated?

Current conditions refresh every 3 hours when the cron runs. Hourly data updates every 30 minutes. The 7-day forecast, luck factor, and packing notes are all pre-computed at the same time.

What is the luck factor?

We compare the 7-day forecast to the last 5 years of marine data for the same week at Cimaja. The delta tells you whether conditions are shaping up better, worse, or about the same as a typical late May.

How is 'best session' picked?

We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.

Where does the data come from?

Open-Meteo's Marine API (swell height, period, water temperature) and Weather API (wind and conditions).

Does the score capture local knowledge?

Honestly, no. Every break has tide windows, swell directions and reef contours that a global model cannot see. Treat the score as a starting point, then check a local cam.
