The Lowdown

Alright, let’s have a look at what’s coming up. This is Rusty, and I’m talking about Bicas.

Right off the bat, I’ve gotta be straight with you – the next couple of weeks are looking pretty grim for any decent surf. The water temp here is sitting around 67°, which is pretty much normal for this time of year, so no surprises there. But the swell? It’s just not happening.

We’ve got a long stretch of nothing from Tuesday the 14th all the way through to the end of Wednesday the 22nd. That’s over a week of flat to tiny, weak waves. The swell heights are bouncing between 1.0 ft and 4 ft, but the periods are short and the winds are mostly onshore or cross-on, with just a light breeze to a fresh breeze. The combined energy is weak, mostly under 100 (89, 70, 42, 76, etc.), and the wave comment is “poor surf conditions” every single time. Honestly, I wouldn’t bother paddling out – it’s a waste of energy.

Things start to look a little more interesting on Thursday the 23rd, but still not good. The swell picks up a bit – 3 ft to 4 ft from the WNW – and the energy gets into the moderate range (150 and 148), but the winds are onshore and fresh, so it’s messy. Still poor.

There’s a small window of hope early on Saturday the 25th. The swell jumps to 6 ft from the NW with a period of 12 seconds, and the combined energy hits 1372 – that’s strong. But the wind is cross-on from the NNW at 12 mph, making it choppy. The comment says “marginal surf forecast or questionable tide conditions.” It’s not great, but it’s the best we’ve seen. Bicas is a rarely breaking reef, and it wants an optimum swell from the west. This is NW, so it’s not ideal. A 6 ft swell on a reef that’s inconsistent is really only for the advanced crew. The onshore chop isn’t helping.

After that, the rest of the run into the end of the month is a mix of moderate to strong energy (273, 396, 1002) but poor surf conditions, strong onshore winds, and generally messy. The swell on Monday the 27th afternoon hits 7 ft from the NW with a period of 9 seconds, and energy of 1002, but it’s blowing WNW at 19 mph onshore. That’s a bit of a mess, maybe more interesting for kiteboarding than paddle surfing.

So, the standout? If I had to pick one, it’s the morning of Saturday the 25th. Swell is 6 ft from the NW, 12-second period, strong energy, and it’s the only time the comment doesn’t say “poor.” But it’s not clean, and it’s not the right direction. It’s a long shot for the experts. For a better bet, you’d have to wait and see if the forecasts change, because this area is in a pretty blank run right now.

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.
