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.

October in Medewi offers consistent surf with an average swell height of 1.4m and a solid 14.2s period, providing well-formed, powerful waves. The dominant swell direction is from the SSW, with 52.91% of waves in the 1-1.5m range and 31.54% in the 1.5-2m range—ideal for intermediate to advanced surfers. Smaller or larger swells are rare, making conditions relatively predictable. Wind conditions are less favorable, with only 19% of the time being ideal for surfing. The prevailing winds come from the SE to SSE, often blowing at 10-20kph, which can create cross-shore or onshore chop. However, mornings may offer cleaner conditions before the wind picks up. Overall, October delivers reliable, quality waves, but timing sessions around wind shifts will maximize the experience.
