Alright, Rusty here. Let’s have a look at what’s on the cards.
Honestly, it’s a pretty flat start. This 16-day window is looking bleak for any proper surf. We’ve got a gap that stretches from the start right through the whole period with basically nothing worth getting wet for. The only spot that ever offers a chance is Bicas, a reef break that rarely breaks. The first time we see anything that could be called a wave is Thursday morning, July 2nd, but even then it’s just 4ft from the NW with a 10 second period and a cross-shore NE wind at 9 mph. The combined swell energy is weak (340), and the water is 67°, which is bang on average for this time of year. That session is rated a dud.
Friday morning, July 3rd, things get glassy. We’ve got a SE wind at 3 mph, making it glassy, and the swell drops to 3ft from the NW, period 10 seconds. The energy is still weak (162). It’s surfable but very ordinary. Still, it’s the best we’ve got all week. After that, it’s downhill fast – Saturday morning, July 4th, is glassy with a 2ft westerly swell, and Sunday morning, July 5th, is glassy but only 1.0ft. The rest of the days are a mix of onshore winds and tiny waves, with the combined energy barely cracking 100. The swell never gets over 5ft, so it’s safe for beginners, but honestly, there’s nothing to ride.
There is no standout session. No point picking a highlight. The only semi-decent surf is Friday morning, July 3rd, because of the glassy conditions. But it’s tiny. Even then, crowds are possible at Bicas. For a spot that rarely breaks, when it does, people know.
For the second week, it’s more of the same. Days and days of onshore wind and tiny, weak swell. There’s a brief moment on Tuesday morning, July 14th, with a 0.7ft swell from the SSW with a 16-second period, but that’s groundswell, and with no size, it’s just a long wait for nothing.
Mate, this is a blank run. If you’re a surfer in this region, this is one of those times to find something else to do. The forecasts can change, but right now, there’s nothing I’d recommend.
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.
