The Lowdown
Alright, I'm gonna level with you – Marlin is looking dead quiet for the whole 16 days. Every single session, from Monday 7th September right through to Tuesday 22nd September, is marked as poor surf conditions. Not one single standout.
Monday 7th September kicks it off with a weak 3ft swell from the east, a 6-second period, and a cross-on breeze from the ENE at 9 mph. The combined energy is only 138 – that’s weak. It's choppy and ugly. Monday afternoon is the same, barely 3ft, 8-second period, but still onshore and weak at 154 energy.
Tuesday 8th September drops even smaller, 2 ft in the morning and 2 ft in the afternoon, with onshore winds. The energy falls to 98 and 131. Wednesday the 9th sees a slight bump to 4 ft, but it's short-period slop from the ESE and the wind is still on it. The energy hits 282 in the morning, but it doesn't mean anything – it's messy.
Thursday 10th September gives a different flavor – the swell swings south with a longer 12-second period, pushing 3 ft. The energy climbs to 440 (moderate), but the wind is onshore or cross-onshore, so it stays poor. You get that longer period, hinting at better shape, but the onshore wind and small size ruin it.
Friday 11th September has the biggest swell of the first week at 5 ft, but with a short 7-second period and onshore wind, it's just lumpy, poor quality. Energy is 410. That's too big to be fun in these conditions for a beginner, and not clean enough for anyone else. The whole weekend, 12th and 13th, is more of the same: 4 ft to 5 ft, cross-onshore winds, choppy.
The second week, from 15th September onward, stays small and poor. Swell heights hover around 3 ft to 3 ft most days, with cross-onshore wind and weak energy dropping as low as 92. Even a 5 ft pulse on Saturday 19th September comes with onshore or cross-onshore wind and a poor wave state. Nothing changes.
Look, for this whole stretch, there's nothing to get excited about. The winds are almost always onshore or cross-onshore, the swell is either too small or poorly organised. Marlin is a beginner spot, and on these days, even the small stuff is too choppy to be fun. This kind of blank run is normal for the area.
Save the board for another time. Go for a swim instead.

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.
