The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a long stretch ahead, and honestly, it’s a slow grind for most of it. The first week or so is pretty flat and weak, with only tiny, unexciting swell. The real standout is tucked away at the very end of the forecast, so you’ll need some patience.
We start off with small, clean conditions at Arpoador on Tuesday morning, the 28th of July. A light 1.6ft southerly swell is rolling in with a 12-second period, but the combined energy is weak, sitting at just 127. It’s clean with a light northerly offshore, but it’s tiny. You can get wet, but it’s not going to get the heart racing. The water temperature is about average for this time of year.
The next few days are a tough watch. Wednesday afternoon the 29th turns glassy for a short window, with the swell ticking up to 2ft, and the energy rises to 167, but it’s still ordinary. By Thursday and Friday the wind gets messy, and the swell doesn’t have the juice to overcome it. It’s a lot of poor surf and very ordinary conditions.
The first weekend of August is a mixed bag. Saturday morning the 1st is clean again with a 1.6ft south swell and 12-second period, but the energy is a weak 148. Sunday morning the 2nd has a 2.3ft ESE swell, but the period is a short 6 seconds, so the waves will be mushy. The combined energy is only 74. It’s surfable, but not exciting.
We see a slight uptick in energy mid-week, particularly on Tuesday afternoon the 5th of August, when a 2ft S swell with a 13-second period pumps the combined energy to 242. But the wind is cross-shore, and the quality is poor. You’ll see some lines, but it’s not clean.
The real moment to keep an eye on is Tuesday morning, the 11th of August. This is the standout. Arpoador gets a 3ft southerly swell with a nice 12-second period, and the combined energy jumps to 415 – that’s a solid, punchy amount of energy. Best of all, it’s glassy. A light NNW wind, zero chop, the ocean will be a mirror. The waves will have shape, length, and clean faces. This is the one to circle on the calendar. It’s a long way out, so the forecast could shift, but right now, that window looks like the best surf we’ve got on offer.
The following day, Wednesday the 12th, falls back into poor conditions with cross-shore winds and weaker energy.
The crowd at Arpoador can be a factor, as it’s listed as “often” busy. But on that Tuesday morning glass-off, if you’re early, you’ll have a chance at a few clean ones to yourself.
So, to sum it up: the first week is a waiting game. The best bet is that Tuesday, the 11th of August. Get out there for the dawn patrol and you’ll be rewarded.

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.
