The Lowdown

Alright folks, Rusty here. Let’s be straight with you about the surf ahead. We’re looking at a real mixed bag over the next couple of weeks, and for most of it, we’ll be scratching for anything rideable. The first solid window doesn't open up until around the 11th of August, so we've got a bit of a wait.

Right now, until about the 11th, it's grim. Small, weak swell and mostly onshore or cross-shore winds making a mess of things. The end of this week and the start of the next look pretty flat.

Now, a classic example is Arpoador. A bunch of these mornings will be clean but with barely any swell, like Friday the 31st: 2ft of south swell, period of 10 seconds, and the energy is weak (122). It’s surfable but honestly just ordinary. The wind is glassy though, which is nice that morning. But then the afternoons turn to junk, like Saturday the 1st, when it’s cross-shore and bumpy.

You'll see a pattern – a few clean early sessions with small waves, but nothing with any punch. The water temp, by the way, is sitting about average for this time of year, so no surprises there. The swell direction is mostly from the south, which is what Arpoador wants.

There's a real gap from around the 8th to the 11th with almost nothing. Then things change. On Tuesday the 11th of August, the swell starts to fill in, but it’s still messy and the wind is on it. That evening we see 5ft of south swell, but the onshore breeze is going to ruin it.

But then, Wednesday morning, the 12th of August, is our standout. The swell is around 5ft from the SSE with a period of 11 seconds, and the energy jumps up to a solid moderate level (469). The big news is the light offshore wind. It's going to be clean, lined-up, and that's the best conditions we've seen in the whole run. This is the one to circle on the calendar. It's just over a week away, so treat it as a promising call, not a certainty, but all the signs are there.

After that, Thursday the 13th and Friday the 14th have small, clean mornings again, but nothing special. The energy is still moderate, but the swell just doesn't have the same size.

So, bottom line: if you've got flexibility, wait for the morning of the 12th of August. That's our shot at something genuinely good. Otherwise, a few small and clean early paddles on the smaller days are all we're getting.

Rusty signing off.

Information about the Arpoador Surf forecast

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

Arpoador is 14 km (9 miles) from the very large city of Niteroi. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Niteroi. Niteroi has rooms for a wide range of budgets as well as cheap car hire and transport links.
