Alright folks, Rusty here. Let’s cut to the chase with this Bicas forecast. I’ve gotta be straight with you – the next couple of weeks are looking pretty grim for a proper paddle session.
We’ve got a window of no real surf on offer stretching from now all the way up to around the 19th of July. The only flicker of life is on Sunday the 19th of July morning. The swell is tiny, just 3 ft from the NW, but the wind is glassy – dead calm. The combined wave energy is only 121, so it's weak. The water temp is sitting at 69°, which is about 2° warmer than normal, so it’s pretty pleasant for this time of year. It’s surfable, but it’s ordinary. For a break that rarely breaks and can get crowded sometimes, it’s not the epic session we’re looking for.
The real standout, and I mean the only one worth circling on your calendar, is Monday the 20th of July morning. The wind is offshore from the SSE at 6 mph, the swell is 4 ft from the NW with a short period of 7 seconds, and the combined energy is moderate at 207. There’s a bit more push in the water. It won’t be world-class, but with clean conditions and the offshore wind, it’ll be the best of the bunch. This is a reef break (Bicas) and the optimum swell direction is W, but we’re getting NW, so it won’t be perfect, but it’ll be rideable.
After that Monday morning, we’re back to onshore junk. There are a few days in the second week where the swell picks up to 4 ft and 5 ft, but the wind is howling onshore from the NW, making it a mess. For a reef break, that setup looks more interesting for kite surfing than paddle surfing. So, if you’re itching for a wave, hit it on Monday the 20th morning, and be patient otherwise.
Rusty.

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.
