Alright, Rusty here again. Let's talk about the same stretch of water, but in the old units.

We've got a slow start, so don't get your hopes up for the first few days. The surf is pretty much a no-go through Monday the 13th and Tuesday the 14th. The wind is all wrong, and while there's a lot of energy in the water, it's just sloppy and ugly.

The first real chance to get wet is Wednesday morning, July 15th. Arpoador is looking at a clean 5-foot swell from the SSE, and the wind is a light offshore from the NNE. That's a perfect combo. The period is 11 seconds, so it's a proper groundswell that will wrap in and give you some nice, long lines. The water is about 72°, which is normal for this time of year. It's a good session for a beginner or intermediate, just know that the crowd is often there.

The quality sticks around for Thursday the 16th. Another morning with a light offshore wind and a clean 4-foot SE swell, also with that same 11-second period. The energy is a bit lower, but it's still very fun.

Things get a bit quiet for a while, with a significant lull from the 18th through the 24th. The swell drops off, and the energy numbers get really small. Then, all that changes on Sunday, July 26th. That's the standout. The morning session has a clean 5-foot S swell (14-second period) and a light offshore breeze. That's a beautiful, high-quality groundswell. The afternoon is even better, with the swell hitting 6 feet from the S, still with that 14-second period, and the wind is a light cross-offshore. The energy is a solid 1471, so it's a punchy, powerful wave. This is for the experienced crew only.

The final days, the 27th and 28th, have some serious size – up to 8 feet – but with onshore winds, making it tricky and messy. It's a big, powerful ocean out there, but not the cleanest.

So, your best windows are the clean, steady waves from the 15th to the 17th, and the absolute fire session on the 26th of July. The rest is a gamble.

Rusty.

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.
