The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s on the menu for Beliche over the next couple of weeks.
The forecast opens up with some energy in the water, but the conditions are a real mixed bag for the first week. We’ve got a solid pulse of swell arriving, but the wind is the main story for the first few days. The ocean is running warm for this time of year, about a degree and a half cooler than usual at 69°, so you’ll feel that little nip in the water.
Friday 28th kicks things off with a clean 7ft NW swell (1090 combined energy) but a stiff 16 mph NNW cross-off wind is going to make it a windy, bumpy affair. Not worth paddling out unless you’re desperate. Saturday 29th sees the swell dropping to 6ft NW, with a strong 19 mph offshore wind from the N. It’ll be clean, but the wind is right on the edge of being too strong to be comfortable.
We then hit a proper lean spell. From Sunday 30th right through until Wednesday 3rd September, the waves are small and the wind stays punchy. There’s a consistent offshore flow, but the swell height is mostly under 5ft and the period is short (8-9 seconds), giving us weak, disorganised lines. The combined energy drops well below 500, which tells you it’s pretty gutless. You could get a slide on Thursday 3rd, with a 5ft NW swell and a gentle 9 mph offshore breeze – but it’s still ordinary.
The end of the first week and start of the second is flat and quiet. Friday 4th, Saturday 5th and Sunday 6th offer nothing over 3ft. There is a little glassy window on the afternoon of the 5th with a 2ft WNW swell, but it’s barely a ripple.
Now, here’s where it gets interesting. The real standout window is shaping up for Monday 8th and Tuesday 9th September. On Monday morning, the swell builds to a clean 5ft NW groundswell with a 12-second period, and the offshore wind is a moderate 16 mph from the N. That’s decent. The combined energy jumps to 595. But the true winner is Tuesday 9th September morning. We’ve got a solid 8ft NW swell (1011 combined energy) with a moderate 12 mph offshore breeze. That’s a proper session, clean and with plenty of power. That afternoon holds at 8ft, but the period drops to 9 seconds. Still good, but the morning is the pick.
After that, it fades again. Thursday the 10th still has a 7ft NW swell but the wind swings cross-off, and by Friday the 11th it’s back to small, ordinary surf. The 12th is flat and not worth considering.
The best on offer: Get on it Tuesday 9th September morning at Beliche. That 8ft NW swell with clean offshore wind is the call. A close second is Monday 8th September morning for the longer-period groundswell.
There’s a long gap of poor to flat surf from late August through to early September, but the 8th and 9th make the wait worthwhile. Remember, long-range calls like that are promising but not set in stone.
Stay stoked,
Rusty.

Information about the Beliche Surf forecast
The above surf forecast table for Beliche provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Beliche can be found by selecting the local surf guide option on the grey menu. Our Beliche 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 (Beliche) 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 Beliche 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.
Beliche is 29 km (18 miles) from Lagos. If you plan a holiday in The Algarve, look for hotels and other accommodation in Lagos. Lagos has rooms for a wide range of budgets as well as car hire and transport links.
