The Lowdown

Alright, Rusty here. Let's have a look at what's cookin' for Arpoador over the next couple of weeks.

Right off the bat, we've got a bit of a slow start, but Thursday afternoon the 10th kicks things off nicely. The water’s sittin' at a beautiful 73°, which is a touch warmer than normal for this time of year, so that's a bonus. We’ve got a clean 3 ft south swell rolling in with a 12-second period, and the wind is dead glass – a total dream. The wave energy is moderate, about (345), and it’s gonna be perfect for getting out there. This is the standout of the first few days: glassy conditions and fun, clean waves. Arpoador is a consistent break and it's fairly exposed to this south swell, so it's working well. Keep in mind it can get crowded here, so bring your patience.

Friday the 11th sees a bigger south swell pushing 4 ft with a very long 14-second period, and wave energy jumps to (517). The morning wind is a bit cross-on though, so it might be a little bumpy. The afternoon cleans up with a cross-off breeze, but the scores aren't as high for quality. Saturday the 12th is tiny and messy, not worth paddling out.

Sunday the 13th is a write-off with rain and poor conditions, just leave the board at home. Monday the 14th is a real treat, especially for the more experienced crew. We've got a punchy 5 ft swell from the SE, though it's a short period at 8 seconds. The wind goes glass in the morning and then offshore in the afternoon. The wave energy is strong at (532) for the morning and (442) in the arvo, and with the offshore breeze, the waves will be clean and hollow. The 5 ft height in the afternoon is getting up there, so it's more for the guys who know what they're doing.

After that, the week gets a bit messy with onshore winds and rain until we hit a proper gem. Thursday the 17th and Friday the 18th have some solid, clean south swell (4 ft to 6 ft) with good energy and clean conditions, but the fly in the ointment is Saturday the 19th. That morning we’ve got chest to head-high 6 ft swell from the east, a short 7-second period, but the wind is offshore from the NE, and the wave energy is strong (487). The conditions will be clean and fun.

Now, here’s the real standout of the whole outlook. Look at Thursday the 24th and Friday the 25th. We’ve got a lovely long-period south swell (12 to 14 seconds) with wave heights holding around 5 ft to 5 ft. The combined energy is proper strong, hitting (887) and (999). The wind is forecast to be light offshore or glassy on the Thursday and cross-off on the Friday. This is the one to circle on your calendar. It’s a full week and a half away, so take it with a grain of salt, but the potential is massive for clean, powerful lines. The swell direction from the south is exactly what Arpoador wants.

No other options in the finder, so it's all about Arpoador. For the first half of the run, Thursday the 10th is your best bet for clean fun. For the second week, keep a close eye on the 24th and 25th – that could be the session of the month.

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.
