Right then, let's talk about Santo Amaro. It's a point break that takes a south-west swell, but the truth is, the whole sixteen-day window looks pretty quiet. There are a couple of good days in the middle where the ocean wakes up, but for the most part, we're staring at a long stretch of no real rideable options.

We kick off on Saturday, July 4th, with tiny 2ft WNW swell, water temp's around 68°, which is about normal for the time of year. The morning's glassy, which is a nice look, but with combined energy down at 90, it's weak. It stays small and clean through the rest of that first week, with heights rarely pushing past 2ft. That's a week of nothing really worth paddling out for.

Now, come Saturday, July 11th, things change. We get a proper pulse of swell – 7ft from the NW, period a short 8 seconds, but the combined energy jumps to 699, which is strong. The wind's offshore from the NNW in the morning, so it'll be clean. But that size, 7ft, at a point with that short period? It'll be lumpy, punchy, and honestly, for experts only. Not a beginner's day. The ratings say it's marginal, and I get that. It's powerful, but messy. The afternoon picks up a cross-off wind, still big, but the score drops. That Saturday is the one standout, but it's not for the faint-hearted.

Sunday the 12th is a cruel joke. The swell collapses to less than 1ft, a 19-second groundswell from the SW. That period is super long, but the energy is pathetic at 23. It's a ghost. You'd see a ripple every few minutes. The rest of the week stays tiny, with nothing above about 2ft until Sunday the 19th, when it tries to build again with a 3ft WNW swell, period short, energy moderate at 114. But it's still classed as poor.

So here it is: the only real shot in this whole window is Saturday the 11th. Big, offshore, strong energy. But it's a wild one. The rest of the time, the ocean's on a go-slow. The combined swell energy is weak (under 100) for almost every other session. You could get a longboard out on the glassy mornings early on, but it'd be a fight for a knee-high slop. Keep an eye on the charts, mate. These flat runs don't last forever.

Rusty.

Information about the Santo Amaro Surf forecast

The above surf forecast table for Santo Amaro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Santo Amaro can be found by selecting the local surf guide option on the grey menu. Our Santo Amaro 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 (Santo Amaro) 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 Santo Amaro 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.

Santo Amaro is 2 km (1 miles) from Carcavelos. If you plan a holiday in Lisboa, look for hotels and other accommodation in Carcavelos. Carcavelos has rooms for a wide range of budgets as well as car hire and transport links.
