Medewi - surf spot statistics

Best Surf Season (October - March)

The heart of the wet season brings the NW Monsoon to life, and for Medewi, that means a dramatic swing toward offshore wind conditions. With the wind blowing from the north through east-northeast a significant portion of the time, the wave face stays clean and the long-period groundswells from the SSW and SW wrap beautifully into the bay. Average swell heights hover in the 1.0 to 1.2m range, but the 12-14 second periods give them real punch. February and March shine brightest – the wind is ideal nearly 40% of the month, and the swell direction is locked in. This is when you can count on rippable, classic Medewi lefts with minimal chop.

Fair Surf Season (April - May & September)

As the monsoon transitions, the trade winds begin to build from the southeast, but the swell quality can still be solid. April and May see average swell heights climb to 1.1-1.2m and periods pushing 13-14 seconds, driven by deepening Southern Ocean lows. The catch: the wind starts clocking around to the ESE and SE more frequently, turning the lineup choppy and sideshore. However, the percentage of offshore wind (from the north) remains around 30-35%, so if you pick your windows, you can score fun, powerful waves before the onshore fog sets in. September offers a similar story – the swell is still pumping but the wind is ideal only 11% of the time, making it a gamble for the dedicated.

Low Surf Season (June - August)

The SE trade wind season hits full stride from June through August, and conditions at Medewi become a battle. While the average swell height peaks at 1.3-1.4m with 14-second periods – some of the most powerful swells of the year – the wind blows from the ESE and SE over 80% of the time. That puts the breeze directly onshore for this south-southwest-facing beach, creating choppy, bumpy faces that are tough to surf. The percentage of ideal offshore wind plummets to just 14-18%. When a rare northernly wind does align, the waves can be epic, but those days are few and far between. Overall, this is the most challenging period for consistently good surf.

October: The Turnaround Begins

October is the start of the true transition into the wet season. The SE trades are weakening, and the monsoon trough begins to shift. Swell from the SSW is absolutely dominant at 87.7%, with average height 1.2m and period 13.5 seconds. Over half of the swell falls in the 1-1.5m range (60.1%), and 8.8% is 1.5-2m. This is solid, rippable surf. The wind pattern is still heavily onshore from the SE, SSE, and ESE (combined over 70% of observations), but the wind speeds are lower than in July and August. The ideal offshore wind is still only 11%, but the N and NNE directions are starting to show up more frequently than in previous months. October offers glimmers of perfection when the wind aligns, and the swell is consistently good.
