Keramas is a world-class right-hand reef break on Bali's east coast, Indonesia. The wave breaks over a sharp coral reef, producing fast, hollow barrels that have hosted the WSL Championship Tour. It works best in the dry season with offshore trade winds. The rice paddies behind and the volcanic landscape create a distinctly Balinese setting.
Needs south-east or east groundswell (from Indian Ocean storms wrapping around the south coast). The dry season (April-October) provides offshore westerly winds. Best at mid tide. The 4-8ft range produces world-class barrels. Morning sessions are typically cleanest before the trade wind shifts.
The main peak breaks over a defined section of reef. The right runs along the coral shelf with barrel sections. The take-off is tight and specific. Watch from the beach to identify the peak.
Very shallow coral reef. The wave is fast, powerful, and breaks close to the reef. Getting caught inside is painful. Urchins and fire coral. Strong currents on bigger days. Experienced surfers only. Booties/reef shoes recommended.
Access from the beach road behind the reef. Short paddle out through the channel. Local warungs (food stalls) and a few hotels nearby. Sanur town (15 minutes) has full facilities.
Moderate to busy during peak dry season. 15-25 people on good days. The WSL event has raised its profile significantly. The local Balinese crew and visiting professionals share the lineup. Morning sessions before 9am are quietest.
Keramas works on a different swell window to the Bukit Peninsula spots (Uluwatu, Padang Padang). When the Bukit is flat or onshore, Keramas can be firing with offshore winds. Night surfing under floodlights sometimes happens (Komune Resort has lights). The rice paddies behind are beautiful. Sanur is a pleasant base.

Based on historical weekly averages
Combining historical conditions with school holiday crowd pressure to find the sweet spot.
How busy each week is based on school holiday overlap from feeder markets.
The timing score combines two signals: historical conditions quality (how good the skiing or surfing typically is in a given week, based on 5 years of weather data) and crowd pressure (how many of this destination's feeder markets have school holidays that week).
Crowd pressure is weighted by each feeder country's share of visitors. If 40% of a resort's visitors come from France and France is on holiday, that contributes 0.40 to the crowd pressure score. Crowds can reduce the timing score by up to 35%, ensuring conditions still matter most.
Scores: 5 = great conditions with low crowds (the sweet spot). 4 = great conditions with moderate crowds, or good conditions with low crowds. 3 = average. 2 = below average conditions or very crowded. 1 = poor conditions or peak holiday chaos.

We compare the 7-day forecast to the last 5 years of marine data for the same week at Keramas. The delta tells you whether conditions are shaping up better, worse, or about the same as a typical mid-June.
We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.

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.
The best week for surf at Keramas is the week of 30 November (score 3/5) with low crowds.
Next to nothing in the water. Check back tomorrow. Reasonable period putting some grunt behind each wave. Onshore wind making a mess of the surface. Best conditions early morning before the sea breeze arrives. Not enough swell to get this spot firing properly.
Heads up: thunderstorms forecast, and jellyfish: peak season.
