The Lowdown
Alright folks, Rusty here. Let’s check out the surf for the next 16 days. We’re looking at a slow start, but the second week has a couple of real beauties.
The first solid recommendation doesn’t come until the early morning of Thursday, August 23rd. Before that, we’ve got a few days of choppy, onshore junk, so don’t bother.
The standout early on is Thursday morning the 23rd. Miramar will be a clean 4ft from the W with a 10-second period. The combined energy is moderate (351), and we’ve got a light SSE breeze blowing cross-offshore. That’s going to give you clean, lined-up waves. Water temp is about average for this time of year. Crowds are possible, so paddle out early.
Monday morning the 24th brings a bigger pulse of energy, with swell hitting 7ft from the WSW (601 combined energy). That’s strong, pushing into the 8ft range, so it’s strictly for the experts. The wind is solid cross-offshore from the S at 19 mph, keeping it clean. The period is a short 9 seconds, so it’ll be a bit fat and dumpy, but there’s power for the experienced.
The rest of the first week and into the second is a mix of poor conditions, onshore winds, and choppy water. There’s a gap from the 24th afternoon all the way through to the 31st afternoon with no real recommendations. The 31st afternoon sees a huge spike in energy (750) with a 4ft swell from the NW and a long 12-second period, but the wind is cross-on, so it’s messy.
The true standout of the whole outlook is Tuesday morning, the 1st of September. Miramar is looking like a dream. A 4ft WNW swell (357 combined energy) with a 10-second period, and the lightest of NNE breezes, almost glassy. That’s cross-offshore, and it will be glassy perfection. The energy is moderate, and the long period will give you those long, arcing lines. This is the one to mark on your calendar.
After that, the surf fades back into smaller, wind-affected slop through the first week of September.
So, in short: hit it Thursday morning the 23rd for a fun, clean session, and lock in Tuesday morning the 1st of September for the best swell and conditions of the entire run. It’s a wait, but that one will be a classic.
Rusty.

Information about the Miramar Surf forecast
The above surf forecast table for Miramar provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Miramar can be found by selecting the local surf guide option on the grey menu. Our Miramar 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 (Miramar) 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 Miramar 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.
Miramar is 5 km (3 miles) from the city of Canidelo. If you plan a holiday in Douro and Minho, look for hotels and other accommodation in Canidelo. Canidelo has rooms for a wide range of budgets as well as car hire and transport links.
