The Lowdown
Alright, let’s talk about what’s happening at Marlin. Honestly, it’s a rough 16-day stretch. There aren’t any good surf options in the entire period, so we’re looking at a pretty barren run. The guide notes say Marlin is an exposed break that gets swell, but the wind and swell direction just aren’t playing nice.
In the first week, from August 10th through the 16th, we’ve got onshore and cross-onshore winds from the ESE and SSE, blowing right into the waves. Swell heights range from 3 ft up to 7 ft, but it’s all short period—around 7 seconds—and the energy is weak to moderate. The water temp is about normal for the season. Every session is poor, with a few days of rain showers and choppy, messy conditions. Not worth suiting up.
The second week, from August 17th to the 25th, is more of the same: onshore and cross-onshore winds, mostly from the E or ENE, and swell sizes dropping to 2 ft to 4 ft with short periods. There is one window on the morning of August 22nd that shows a 4 ft south swell with a very long 17-second period, and a cross-shore NNE breeze at 9 mph. The energy is strong at 1064, but it’s marginal due to tide or something, and the afternoon gets choppy again. The swell direction is from the S, which is the optimum for Marlin, so that morning is your best look—but it’s still not clean or consistent enough to call a go.
This is a real dry spell for Marlin. It’s unusual for such a consistent spot to go this quiet, and it usually doesn’t stay poor for long—forecasts can change. But right now, I’d say save your energy and wait for better days.

Information about the Marlin Surf forecast
The above surf forecast table for Marlin provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Marlin can be found by selecting the local surf guide option on the grey menu. Our Marlin surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Marlin) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Marlin may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
