The Lowdown
Alright, let’s put this in feet, miles per hour, and Fahrenheit, same story, different numbers.
We’re looking at Canal, a river break that needs a south swell. Water temp is a normal 72°F for this time of year.
July is dragging its feet. Small swell around 3ft, but the wind is messy. Sunday has cross-shore chop, Monday morning cleans up with a light offshore breeze, but the swell is tiny and the period is short. Not worth paddling out. Tuesday through Thursday are basically a flat spell.
Friday July 31st morning is a quiet chance. Glassy surface, 3ft of south swell with a 10-second period. Not much energy (172), but if you need to get wet, it’s clean.
The first real highlight is Saturday August 1st morning. We’ve got 3ft of clean south swell, a solid 12-second period, and a light offshore breeze from the NE. The energy is moderate at 290. This is the best combination of size and wind in this first week. Crowds might show up – it’s a popular window.
Sunday August 2nd morning is a decent follow-up with 3ft of 10-second swell and the same clean offshore wind.
Then it goes quiet again. Monday 3rd offers a tiny 2ft east swell with a short period – skip it. Tuesday 4th has a 3ft south pulse but the wind is cross and lumpy.
Wednesday August 5th morning is a gem. Glassy conditions, 3ft of 12-second south swell, and a strong energy reading of 451. It’s clean, knee-to-waist high, and beautiful. But the afternoon jumps to 8ft from the SSW with a 14-second period. That’s big water, expert territory, and the energy is massive (2378).
Thursday August 6th is for the brave. Swell hits 10ft from the S/SSW, 13-second period, and energy in the 3000s. The wind is offshore in the morning and glassy in the afternoon – but this is way too big for Canal. Only big-wave specialists should even think about it.
From Friday 7th onward, the swell drops from 8ft back down to 3ft, with mostly clean winds. The sessions on Saturday 8th and Sunday 9th are still too big for comfort, but by Monday August 10th morning, we’re back to a fun 3ft of clean 11-second swell with a light offshore breeze.
The two best bets? Saturday August 1st morning and Wednesday August 5th morning – clean, fun, manageable surf. The massive stuff mid-week is for experts only.

Information about the Canal Surf forecast
The above surf forecast table for Canal provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Canal can be found by selecting the local surf guide option on the grey menu. Our Canal 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 (Canal) 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 Canal 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.
Canal is 3 km (2 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
