The Lowdown

Alright folks, Rusty here. Let's have a look at what the next couple of weeks are shaping up like for Ribanceira.

Honestly, the first week is a bit of a dud. We’ve got a solid stretch of flat, messy conditions from Saturday the 15th right through the entire week. The swell is tiny and the wind is all over the shop, mostly onshore or cross-onshore, keeping things choppy and unrideable. You’re looking at a blank run of about six days with nothing worth paddling out for. The water temp is sitting about average for this time of year, nothing wild there.

Things start to look a little more promising on Friday the 21st. The morning session shows a clean 4ft swell from the SSW with a light offshore breeze, so it’s surfable, but it’s very ordinary. It’s a glimmer, not a green light.

The real standout, and the only one worth circling on the calendar, is Sunday the 23rd of August. The morning is the pick of the entire forecast. We’re looking at a solid 10ft groundswell from the S, with a very long period of 14 seconds. That’s a powerful, clean set-up, and with a moderate offshore wind, it’s going to be pumping. The combined energy is a massive 6156, which is in the very strong category. This is expert territory though – that size is not for the faint-hearted. It’s a sandbar set-up, so that long-period swell might be a bit straight, but with that much juice and offshore wind, it’ll be a special session for the experienced crew.

The tail end of the week from Monday the 24th to Wednesday the 26th sees the swell dropping but staying clean. We’ve got solid 7ft to 6ft swells from the S and SSE with light offshore winds and glassy conditions. The energy is still moderate to strong (around 1300-949). These are proper, green, clean waves – a great run of days for intermediate surfers once the big Sunday swell drops.

Thursday the 27th onwards it fades back into small, poor conditions for the weekend. The window closes pretty quickly.

So, bottom line: surf the first week out. The clear winner is Sunday the 23rd of August morning for the experts, but the whole stretch from Monday the 24th to Wednesday the 26th is a solid run of clean, fun waves.

Rusty.

Information about the Ribanceira Surf forecast

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