Alright, let’s talk about what Arpoador’s got cooking.
The first few days are pretty quiet – you’re looking at small, choppy waves and onshore junk until we get to Monday, July 6th. That’s a few days of not much.
Come Monday morning, we see a 1.4m south swell with a light northeasterly breeze, making it clean and cross-offshore. The energy is moderate (687), and it’s a consistent break, so you’ll find a few. It’s a beginner-friendly wave, so don’t expect anything too heavy.
The real standout is Saturday, July 18th. That morning brings a 1.3m south swell with a super long 18-second period – that’s proper groundswell. With a light offshore from the NNE, the waves are going to be glassy, clean, and well-shaped. The energy is strong (1168), and it’s a consistent spot, so you’ll get plenty, but it’s often busy, so get there early. Water’s sitting around 73°F, which is about normal for the season. That Saturday morning is your best bet by a long shot.
The days before that, like the 14th and 15th, are mostly onshore and messy. You get a few cleaner windows around the 11th to the 13th with chest-high waves and light winds – good for a fun session on a longboard.
The 10th of July has a small offshore window, but it’s only 0.8m – more of a longboard or grovel board day.
Focus on that Saturday the 18th. That’s the one with the most juice and the cleanest conditions. The rest you gotta pick your moments.

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.
