The Lowdown
Alright folks, Rusty here. Let's have a look at what's on offer for the next couple of weeks. To be straight with you, it's a pretty bleak run for Forjos. The whole 16-day outlook is a long stretch of poor surf conditions with nothing I'd call a standout. From now right through to the end of the month, every session is rated as poor. That's a solid two-week gap with no decent surf.
The core issue is the wind. We've got persistent moderate to fresh cross-onshore and onshore breezes from the east and southeast, which is just chopping everything up. The swell is hanging around in the 4ft to 6ft range, mostly from the ESE, with a short period of 7-8 seconds. There's a bit of a boost on the 20th of September with a longer period 12-second S swell pushing the combined energy up to 705, but even then the wind is cross-onshore, so it's still messy. On the 18th, we see the biggest swell of the period at 6ft from the ESE, but with a 7-second period and onshore wind at 19 mph, it's just a blown-out mess. For a beginner-friendly spot like Forjos, any swell over 5ft is already getting big, so that day is a write-off for learners. Overall, wave energy is mostly moderate (207-572) but unusable.
This is a tough one. With all that onshore wind and chop, a beach setup like Forjos looks more interesting for kite surfing than paddle surfing right now. We’re in a poor run, but forecasts can change. Hang tight.

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