The Lowdown
Hey mate, Rusty here. Looking over the next 16 days for Alfagar, it’s a pretty slow spell overall. There’s a lot of small, ordinary swell with only a couple of sessions worth chasing. The water’s sitting around 68°, which is a touch cooler than normal for this time of year—nothing extreme, but you’ll notice it.
The first decent chance is Friday the 21st in the morning. We’ve got waves around 3ft from the WNW, with a clean cross-off breeze out of the NW. The combined energy is moderate at 102, and the period is short at 8 seconds, so expect quick, small waves. That afternoon sees 3ft and 137 energy, but the wind picks up to 19 mph from the WNW—still clean but getting breezy.
Saturday the 22nd morning is the best of the early stretch. Swell drops to 2ft from the WNW, with a 10-second period and a light NW cross-off wind. Clean condition and low energy at 83, but it’s the most surfable we get for a while. That afternoon turns lumpy with a fresh W cross-shore.
Things go quiet until Friday the 28th morning. That’s a solid call: 3ft from the NW, clean NNE cross-off breeze, and energy jumps to 161. The period is still short at 8 seconds, but with the light wind, it’s a fun, clean session.
Then, the standout of the whole forecast lands on Tuesday the 1st of September morning. Only 2ft from the W, but the period is 16 seconds—proper long-period groundswell—and combined energy is a strong 248. We’ve got a solid NNW offshore at 16 mph keeping it glassy. At a reef break like Alfagar, that’s going to produce long, clean lines. The afternoon drops to 2ft with 14-second period, still 212 energy and a lighter NW cross-off.
Otherwise, it’s mostly flat or messy. If you’ve got one session to paddle for, make it the morning of the 1st of September.
Rusty.

Information about the Alfagar Surf forecast
The above surf forecast table for Alfagar provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Alfagar can be found by selecting the local surf guide option on the grey menu. Our Alfagar 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 (Alfagar) 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 Alfagar 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.
