The Lowdown
G’day, Rusty here, your local surf reporter. We’ve got a 16-day outlook for Alfagar, and it’s a pretty drawn-out affair. The first real swell action doesn’t kick in until the end of the period, so be prepared for a long wait through some small, ordinary surf.
From now through most of the next week, we’re looking at a stretch of very small, weak waves. The early days are flat and gutless — Tuesday morning on the 15th is a glassy 1ft from the WNW, but the combined energy is only 33, which is barely a ripple. Wednesday the 16th picks up a touch to 3ft from the NW on the morning, with 153 moderate energy and a cross-offshore breeze, but the period’s short at 8 seconds. No standouts here.
The real highlight, the one worth marking on the calendar, comes much later. Wednesday the 23rd of September morning is the clear standout. You’ll see clean 3ft waves from the west, with a long, powerful 14-second period and strong combined energy of a very solid 510. Winds are calm and glassy — absolutely perfect conditions. This is a reef setup, and with that long-period groundswell, it’ll likely deliver some lined-up, punchy waves. Expect pristine, glassy surf, but be aware this spot is inconsistent and only breaks sometimes, so that makes this event even more special. The water is running a bit colder than usual for the time of year, sitting at 69°, but that’s only a 2° difference, so it’s notable but not bizarre.
Between now and that 23rd, there’s a long gap of over a week with just marginal, poor, or small surf. Thursday the 17th morning offers a chance: 4ft from the WNW with 12-second period and gentle offshore winds from the north, giving clean conditions and moderate energy (311). It’s a solid option but not the true standout. After that, it’s back to tiny, ordinary waves until the 23rd.
Later in the outlook, Sunday the 29th morning has a clean 3ft from the WNW with 10-second period and gentle offshore wind, but the energy is only 135. It’s surfable, but nothing to rush out for.
The best bet across the whole 16 days is that Wednesday 23rd September morning at Alfagar — clean, glassy, and with enough power to make the wait worthwhile.
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.
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.
