The Lowdown
Alright, this is Rusty. Let’s be straight with you – the next couple of weeks are looking pretty bleak for a paddle at Marlin. We’ve got a long stretch of onshore wind and messy, short-period swell, and the models are serving up a big plate of “poor surf conditions” for most of the run. It’s a disappointing start, but hang in there.
The first solid chance of anything rideable doesn’t show up until Sunday, August 3rd. For a full ten days before that, from Monday, July 20th right through to Saturday, August 2nd, it’s a real struggle. The wind is pinned onshore from the ESE to SE, the swell is weak and short-period (mostly 7 to 8 seconds), and the combined energy stays low, barely cracking 500 (542) at its best early on, then dropping to a paltry 110 by the 25th. The water temp is a warm 79°F with a normal anomaly of 0.7°F, so at least you won’t freeze while you’re getting skunked. This spot is consistent, but right now it’s consistently poor.
The first flicker of hope comes on the morning of Sunday, August 3rd. We finally see a marginal surf forecast, with a 6ft swell from the ESE at 8 seconds and combined energy climbing to 678 (moderate). The wind is still onshore from the ESE at 9 mph, so it’s not clean, but it’s a step up from the total washout. By Monday afternoon, August 4th, the energy pushes up to 714 (moderate) with a 6ft ESE swell, but again, the wind is onshore. It’s still a marginal call, and the short period (8 seconds) means the waves will be a bit lumpy and soft. For a beginner-friendly spot like Marlin, this is about as good as it gets in this window, but don’t expect any standout barrels.
Honestly, if you’re an experienced surfer, the whole 16-day window is a write-off. The onshore wind and short-period swell mean the setup at Marlin, an exposed beach, looks more interesting for a kite session than a paddle. The conditions are neither clean nor powerful enough for a proper surf. The only real standout, if you can call it that, is the last couple of days of the forecast when the energy finally gets into moderate territory, but it’s still marred by the wind. For a beginner, the 5ft to 6ft swell on August 1st and 3rd might be a bit much, but it’s the best you’ll see.
So, to sum it up: the first ten days are a total loss. The last six days offer a slight uptick, but it’s nothing to write home about. Keep an eye on the charts, but don’t hold your breath.
Rusty.

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.
