The Lowdown

Alright folks, Rusty here with a look at what Arpoador's got cooking for us over the next couple of weeks. We're in for a bit of a mixed bag, but there's some real promise on the horizon if you're patient.

First up, the start of this run is a bit of a slow burn. The water here is sitting at 72°, which is pretty much what you'd expect for this time of year, nothing wild there.

Thursday the 23rd and Friday the 24th are pretty much write-offs. We're looking at tiny, choppy junkyard surf with cross-onshore winds. The energy is barely there (37) and the waves are just a dribble. Not worth getting wet for.

Saturday the 25th morning is where we finally see a glimmer. The wind goes glassy, and we get a cleaner 1 ft swell from the south with a 10-second period. The energy picks up to a moderate 290. It's a small window, but that glassy morning will be the best of the early days for a beginner-friendly wave.

Sunday the 26th morning is also a beauty. Clean, cross-offshore breeze and a long-period 2 ft south swell (14 seconds) pushing through. The energy is solid at 374. That long period means the waves will have some shape and the sets will be spaced out, making it easier to get outside. The crowds at Arpoador are often there, so expect some company.

We then hit a bit of a lull from Monday the 27th through the end of July. The swell stays small, mostly under 3 ft, and the conditions are just "ordinary" or poor. Not much to get excited about.

Now, hang tight for the first week of August, because that's where the real action is. Tuesday the 4th morning looks promising. A clean offshore wind meets a 5 ft south swell (11 seconds) with a strong energy reading of 473. That's a proper surfable size with good conditions.

But the standout, the one you want to circle on your calendar, is Wednesday the 5th. The morning session is looking like a proper event. We've got glassy conditions and a 10 ft swell from the east-southeast. That's a big wave, folks. The energy is a massive 2177, which is very strong. This is for experienced surfers only – beginners, stay on the sand. The period is 9 seconds, so it's a windswell, but with that size and glassy wind, it's going to be a wild ride.

Thursday the 6th morning is a close runner-up. Clean offshore winds and a 7 ft swell from the east-southeast, with energy at 1121. Still big and powerful, but a notch down from Wednesday. That morning offshore wind will be key.

So, to boil it down: the first week is a slog. The best early offerings are the glassy mornings on the 25th and 26th. The absolute standout is the morning of Wednesday the 5th of August, but it's a heavy, expert-only session. The morning of Thursday the 6th is also a great, powerful option if Wednesday is too big for you.

Stay safe out there, and keep your eyes on the horizon.

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.
