Tago River - surf spot statistics

Best Surf Season (September - November)

The transition between the SW and NE monsoons creates the most favorable blend of conditions at Tago River. During September, the SW monsoon still delivers reliable offshore winds from the south, yet the first pulses of NE groundswell start to arrive, pushing average heights into the fun zone and periods lengthening past 10 seconds. October sees a dramatic increase in swell size as the NE monsoon strengthens, with long-period waves from the N through ENE quadrant becoming consistent. November is the premier month: solid 1.5-2.5m surf is common, and while the wind does become more northerly, the frequency of clean offshore days from the south is still significant enough to produce glassy peaks. This window offers the best trade-off between size and wind quality.

Fair Surf Season (December - March)

The core of the NE monsoon brings a relentless supply of powerful swell. December, January, and February boast the highest average wave heights of the year, often in the 1.5-2.5m range with period averages around 9-10 seconds. The challenge is the wind: the dominant northerly to northeasterly flow blows directly onshore, wrecking the wave face a majority of the time. Ideal offshore winds from the south are rare, occurring only 7-13% of the time. March sees a slight drop in swell size but the wind pattern remains unfavourable, making this a month of potential but frequent frustration. The few clean windows, often linked to a passing cold front or a high-pressure system retreating, can deliver pumping conditions that rival anywhere.

Low Surf Season (April - August)

As the NE monsoon weakens, the SW monsoon (Habagat) takes over. April is a transitional month with average heights dropping to 1.3m and wind quality starting to improve, but still only 16% ideal. By May, the wind shifts definitively to the south and southwest, providing offshore conditions over 39% of the time, but the swell production drops significantly as the fetch shifts away from the optimal NE quadrant. June, July, and August are dominated by small, wind-swell from the E and ENE, with average heights barely reaching 0.8m and periods around 9 seconds. The silver lining is the high probability of clean, offshores winds – up to 70% in August – making this a great period for longboarders, beginners, or anyone looking to log smooth, peelable waves on a smaller craft. Advanced surfers looking for power will struggle to find it.

November: Prime Time for Size

November is arguably the best month for big, powerful surf at Tago River. The average swell height hits 1.6m with a period of 10.0 seconds, but the distribution shows that 34.5% of waves from the NE are in the 1-1.5m range and 25.5% in the 1.5-2m range, with 5.1% over 2m. This means consistent chest-to-head-high sets with plenty of juice. Swell direction is overwhelmingly NE (67%), making the most of the spot's NE exposure. The wind, however, becomes a wildcard: ideal offshore winds drop to 21% of the time as the NE trades strengthen. Northerly (16.7%), NNE (15.2%), and NNW (14.1%) winds dominate, creating onshore conditions the majority of the time. Yet the occasional passing cold front or low-pressure system can swing the wind to the south for a day or two, producing epic, clean, large waves. November is about waiting out the wind and scoring those peaks. When it comes together, you get some of the heaviest and most consistent waves of the year.
