The Lowdown
Howdy, Rusty here, and we’re lookin’ at a spotty run for Beliche. Over the next 16 days, the swell’ll come and go, but the wind’s the main player – mostly offshore or cross-off, so the surface stays clean, but wave size and quality are all over the place. There’s a few days with nothing worthwhile right at the start, so don’t rush.
Friday the 21st is a bust. We got 5ft of lumpy, short-period NW windswell with a fresh 30 km/h offshore, but the energy’s weak (350), and the comment says poor. Not worth it.
Saturday the 22nd is where it gets interesting. Morning brings a clean 5ft swell from NNW with a period up to 10 seconds – that’s more shape and punch. The offshore wind is moderate at 20 km/h, and the energy’s moderate (403). Expect good surf conditions. It ain’t big, but for a sheltered, fairly consistent spot like Beliche, the clean offshore wind and longer period will make for some nice walls.
Sunday the 23rd gets messy. Swell jumps to 6ft from WNW with a long 12-second period, and the energy’s moderate to strong (882), but the wind goes cross-onshore from the SSE. That’ll chop it up. Skip it.
Monday the 24th is a write-off – risk of thunderstorms, onshore wind, and choppy. Tuesday the 25th is worse – small, weak waves (118), no quality.
Wednesday the 26th through Thursday the 27th stays marginal. Swell drops, then picks back up to 5ft on Thursday afternoon with a moderate 25 km/h cross-offshore wind and strong energy (531), but the comment says marginal. The period’s only 9 seconds, so it’s a bit short. If you’re desperate, it’s clean, but don’t expect much.
The standout comes Saturday morning, August 28th. We got 6ft of NW swell with a 10-second period and a solid 25 km/h offshore wind – that’s clean, groomed faces. The energy’s strong (730), but the comment says marginal surf forecast or questionable tide conditions, so watch the tide. This is the best mix of size, direction (NW, matching the optimum for Beliche), and offshore wind in the whole window.
Saturday the 29th is bigger but windier – 6ft with a fresh 30 km/h offshore in the morning, but the afternoon gets a strong cross-off breeze and the comment calls it poor. Skip it.
Sunday the 30th morning is another good one. 5ft from NNW, 10-second period, moderate 25 km/h offshore, and the comment says expect good surf conditions. The energy’s moderate (421). It’s a bit smaller than the 28th, but the conditions are solid. Not a standout because of size, but a fun, clean session.
After that, it tails off. Monday the 31st and Tuesday the 1st of September are small and ordinary – 2ft to 3ft, clean but weak. Wednesday the 2nd stays small. Thursday the 3rd and Friday the 4th see size pick back up to 5-6ft, but the period drops to 7-8 seconds, so the waves will be steeper and less organized. The wind is offshore and strong – up to 40 km/h on Friday afternoon – which makes the surface clean but hard to paddle into. Not worth chasing.
Best bet? Lock in Saturday morning, August 28th. That’s your pick of the 16 days.

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.
