The Lowdown
Alright, let me be straight with you. Looking at the 16-day window for Bicas, I've gotta say, it’s a pretty grim run. We've got a long stretch of poor conditions ahead, with very few windows that are even worth paddling out for. The first bit of anything that could be called surfable doesn't show up until Monday morning the 27th, and even then, it's barely a whisper.
The whole forecast is plagued by onshore winds and weak, short-period swell. Most days, the wind is coming out of the NW or WNW, smashing the surface and making a mess of things. The combined wave energy is low, mostly under 100, just weak energy that lacks any punch (162 for the weak combo on the 26th). Water temp is around 69°F, which is about average for this time of year, nothing special there.
Let’s break it down. The only real standouts, if you can call them that, are the two glassy mornings. Monday morning the 27th, the wind goes NNE at just 3 mph and becomes glassy. The swell is a tiny 2ft from the NW with a short period of 6 seconds, and combined energy is just 62 – a weak, weak offering. It's surfable but very ordinary. Then on Wednesday morning the 29th, we get a total calm – zero wind from the NW, glassy as. Again, it's a small 2ft from the NW, period of 9 seconds, and 68 combined energy. It's tiny and ordinary, but it'll be clean. On the plus side, because Bicas is a reef break that rarely breaks, even a little bit of clean swell here is unusual. Just don't expect much push.
Beyond those two fleeting windows, the rest of the outlook is a write-off. Afternoon winds howl onshore, and while we see a bit more size building into the second week – like Sunday morning the 2nd of August with 4ft from the NNW and moderate energy (292) – it's wrecked by onshore winds. The same goes for the following week: a little more size and period on the 9th and 10th of August (3ft, 10-11 seconds, moderate energy around 200), but the wind is always onshore or cross-onshore. The setup looks more interesting for kite surfing than paddle surfing on most of those afternoons.
To be honest, for a spot that is inconsistent and rarely breaks, this blank run is pretty normal. It’s a tough stretch. Keep an eye on the forecast, because things can change, but right now, it’s a waiting game for a proper swell and clean wind to line up.

Information about the Bicas Surf forecast
The above surf forecast table for Bicas provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bicas can be found by selecting the local surf guide option on the grey menu. Our Bicas 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 (Bicas) 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 Bicas 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.
Bicas is 9 km (6 miles) from Sesimbra. If you plan a holiday in Lisboa, look for hotels and other accommodation in Sesimbra. Sesimbra has rooms for a wide range of budgets as well as car hire and transport links.
