Medewi - surf spot statistics

Medewi, Indonesia, is a consistent year-round surf destination with reliable ground swells dominating the swell mix, rarely dropping below 93% in any month. The best conditions for surfers generally occur from April to June when the swell size averages 1.3–1.5m, offering a solid balance of power and rideability. During this period, wind conditions are slightly more favorable compared to the rest of the year, with good wind days peaking at 40% in April before gradually decreasing. The swell quality remains excellent, with almost no wind swell interference and virtually no flat days. The largest swells arrive from July to September, averaging 1.6m, but stronger onshore winds become more prevalent, particularly from August onward, reducing ideal sessions. The least favorable months are December and January, when the swell drops to 1.2m, and wind conditions worsen, with bad winds exceeding 75% of the time. While Medewi is surfable throughout the year due to its high ground swell consistency, mid-year (April–June) provides the best compromise between wave size and manageable winds, making it the prime window for advanced surfers seeking quality right-hand point breaks with minimal interruptions.

January in Medewi offers consistent surf conditions with an average swell height of 1.2m and a strong, well-spaced period of 13.1 seconds, producing clean, powerful waves. The swell is predominantly from the SSW (accounting for 93.24% of waves in the 0.5-2.5m range), delivering well-organized, ridable waves with a mix of mid-sized (1-1.5m, 62.98%) and occasionally larger sets (1.5-2m, 12.51%). Wind conditions are variable: while 25% of the time they are ideal (light or offshore), WSW and W winds dominate, often blowing at 10-30kph (18.19% WSW, 20.68% W), which can create choppy or cross-shore conditions. Early mornings or protected sections may still provide clean faces, but afternoons frequently see wind-affected waves. Overall, January is reliable for intermediate to advanced surfers, with the best sessions occurring when winds are light or favorable, typically early in the day.
