The Lowdown
Alright, this is Rusty. Let's have a look at what's on the cards for the coming days.
The surf starts off pretty lackluster for a while there, with a real flat spell setting in. We're looking at a gap of nearly a week where it's not really worth paddling out. The first real glimmer of hope shows up on the morning of Saturday, 26 July, but conditions are still pretty ordinary. The jewel in the crown here, without a doubt, is the morning of Tuesday, 5 August at Arpoador. The best on offer is a solid 8ft swell from the ESE, with a clean offshore wind from the NNE. That's big, powerful surf with moderate wave energy (1809) – it's going to be a proper session, but be warned, this is strictly for experienced surfers only. Beginners will be out of their depth.
The water temp is about average for the time of year, so no surprises there.
Let's walk through the whole period. Saturday, 25 July, starts off with some small 4ft S swell, but it's glassy in the morning with a score of 1. The afternoon goes onshore and messy. Sunday, 26 July, the morning is the better option with a 2ft S swell, but it's a long 14-second period, and clean. The afternoon turns choppy. Monday, 27 July, through to Thursday, 31 July, is a write-off. The swell drops to under 2ft, with onshore or cross-shore winds and poor surf. Friday, 1 August, sees a small pulse of 2ft S swell in the morning with clean offshore wind, but it's nothing to write home about. Saturday, 2 August, is similar with a clean offshore morning but small swell.
Now, the window opens properly on Monday, 4 August morning. We get a 3ft S swell with a long 13-second period, and it's dead glassy. That's a good, clean starter. The water is calm, and the wave energy is moderate (366). The afternoon pushes up to 5ft, but the cross-shore wind messes it up.
Tuesday, 5 August morning is the standout. As I said, 8ft ESE swell, offshore wind, and it's clean. That's excellent surf for the experienced. The combined energy is strong (1809). The afternoon is a no-go with a strong cross-shore. Wednesday, 6 August morning is still solid, with a 8ft E swell and offshore wind, but it's a bit smaller and the period is a shorter 9 seconds. Energy is still strong (1279). The afternoon goes cross-shore again. Thursday, 7 August, the morning is a good 5ft SE swell with offshore wind, a solid session for the average surfer. The afternoon gets messy with 7ft E swell and cross-shore wind. Friday, 8 August morning, the final call, is a 4ft ESE swell with offshore wind, but it's unremarkable overall.
So, overall, the wait is painful, but the 5th of August morning is your one true chance to score something special. If you're in the water on that Tuesday morning, you're in for a treat.
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.
