The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s lined up for us. To be honest, the next couple of weeks are looking pretty grim. We’ve got a consistent run of poor surf conditions, and the finder isn’t showing any real standouts. The water temperature is sitting at 79°F, which is about average for the time of year, so at least it’ll be warm while you’re getting frustrated.
The outlook starts with Wednesday, July 15th, and it’s a write-off straight away. We have a cross-on wind from the SSE at 19 mph, making a lumpy mess of the 7ft to 8ft SSE swell. The wave energy is moderate (599-883), but the quality is just poor. That setup looks more interesting for kite surfing than paddle surfing. This cross-on, choppy pattern sticks around hard through the rest of the week and into the weekend. The swell stays between 6ft and 8ft, with periods mostly around 7-8 seconds (short period, weak windswell), and the wind just won’t let up. Saturday the 18th is the same story.
We finally see a change in the wind direction on Sunday, July 19th, turning onshore from the ESE. The swell drops to 5ft to 6ft, and while the wind eases to a gentle breeze, the conditions are still described as poor. Monday the 20th afternoon sees a small improvement, with the wind dropping to a light breeze and the swell rising to 6ft from the ESE, but it’s only called “marginal” at best.
From Tuesday, July 21st, through to the end of the month, it’s a long, flat, and unappealing stretch. The swell drops from 6ft down to 2ft, the wave energy dips into the weak two-digit range (112-166), and the wind is either onshore or light cross-onshore. The last few days of July have a tiny pulse of long-period groundswell from the S (periods of 13-15 seconds) starting on the 29th, but the swell height is only 2ft to 3ft, and the wind is still onshore. It’s not enough to get excited about.
So, there’s nothing I can call a standout here. It’s a long, blank run of poor surf with no real recommendations. The area just tends to go quiet like this. Forecasts can change, but for now, leave the boards at home and check back later.
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.
