The Lowdown
Alright, Rusty here. Let’s have a good look at the next couple of weeks.
First up, we’re looking at Alfagar, a reef break that’s inconsistent and needs a good combo to fire. The water’s running at 65.7°, which is a full 5.4° colder than normal for this time of year. That’s unusual, so you’ll be wanting a decent steamer or a thick spring suit. The combined swell energy is weak for most of the run, barely cracking 100 (24) on the opening Tuesday. Not much to get excited about for the first week, to be honest. Small, weak, and mostly chopped out afternoons.
The first real glimmer comes Thursday morning the 13th. Glassy conditions, 2.6ft from the WNW, period 9 seconds, and the combined energy hits a moderate 120. It’s surfable but ordinary, clean under a calm sky.
Friday morning the 14th is the first true standout. Offshore breeze, 2.6ft WNW swell at 9 seconds, combined energy 92. It’ll be clean with little ripples. Not big, but if you’re on a log or a fish, that’s a fun, uncrowded window. Crowds are only sometimes a problem here, so you might have it to yourself.
Things lift Saturday the 15th morning. Offshore wind again, 4.6ft from the NW, period 8 seconds. The combined energy is a solid 361 (moderate). That’s the biggest wave height in the whole run, but 8 seconds is short period – it’ll be a bit fat and crumbly. It’s good for the average surfer, not too heavy. Afternoon turns to junk with cross-shore.
Friday the 21st morning is the real highlight of the whole 16 days. Offshore cross-off wind, glassy texture. Swell 3.6ft from the WNW, period hitting 11 seconds – that’s proper groundswell energy. Combined energy jumps to 275 (moderate). That’s good shape, defined lines, and you’ll feel the extra push. Alfagar being a reef, it’ll handle that period nicely for a clean wall. This is the morning to clear the calendar.
After that, it quickly drops off again. The Monday the 24th morning shows a 5.2ft NW swell at 9 seconds, combined energy a very strong 497, but the wind is cross-shore. That amount of energy with side wind is messy and drunk surfing. Possibly more interesting for a kite than a paddle.
So, the real pick is Friday 21st August morning – best combination of size, direction, period, and clean wind. Shortboard or step-up, go early. The second pick is Saturday 15th August morning for a slightly smaller but still punchy session.
Overall, there’s a lot of fluff in this forecast, but those two windows are worth surfing.

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.
Alfagar is 3 km (2 miles) from Albufeira. If you plan a holiday in The Algarve, look for hotels and other accommodation in Albufeira. Albufeira has rooms for a wide range of budgets as well as car hire and transport links.
