The Lowdown

Alright folks, Rusty here. Let's talk about Bicas. I've got the whole 16-day window laid out, and I'm gonna be straight with you – there's nothing to get excited about. Not a single standout session in the whole run. The waves are tiny, the wind is mostly onshore, and the whole setup just isn't cooperating.

Bicas is a reef break that rarely breaks anyway, so a run of poor surf is pretty normal for this spot. The guidance tells me it works best with a swell from the west, but we're seeing tiny little WNW and NW pulses all the way through, never getting above 5 ft, and that's only on July 27th afternoon with a fresh onshore breeze. The water temp is sitting around 69°F, which is pretty average for the time of year – nothing unusual there.

Let's run through the dates. From July 17th right through to July 31st, it's a total bust. Every day has "poor surf conditions" marked. The wind is almost always onshore from the northwest, blowing straight onto the break, and the swell heights are measly – mostly under 3 ft. Even when the period stretches a bit, like on July 21st morning with 1 ft and 11 seconds, the combined energy is only 43 (weak) and the wind is onshore. Not worth paddling out.

The only flicker of hope comes on August 1st, Saturday morning. The forecast shows a light cross-offshore breeze from the east-southeast, and the conditions are described as "surfable waves but very ordinary conditions" – that's the only time all period the score isn't zero, and it's a 1 out of 10. Swell is a pathetic 2 ft from the northwest, period 8 seconds, combined energy just 60 (weak). Sure, the wind might make it clean, but the waves are so small it's barely a ripple. By the afternoon, it's back to onshore and poor again.

Bottom line: if you're dreaming of surfing Bicas in this 16-day stretch, forget it. This is a spot that rarely breaks, and this forecast confirms it. Sometimes it just stays flat, and the forecasts can change, but right now there's nothing worth chasing.

Stay patient, keep an eye on the charts, and maybe go for a paddleboard session somewhere else. This one's a dud.

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.
