The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Miramar. It’s a bit of a slow start, so don’t rush to grab your board just yet.
The first real chance to get wet is on Tuesday morning, the 11th of August. We’re looking at tiny 1ft waves from the west-northwest, with a period of 10 seconds. The energy is weak (42), but the wind is glassy, which is a major positive. It’s surfable, but very ordinary. You’ll be fighting for knee-high slop, but at least it’ll be clean.
Things start to look a little more promising later in the week. Wednesday the 12th and Thursday the 13th both have clean glassy mornings with 3ft to 3ft swell from the west, period around 9 seconds. The combined energy creeps up (141 and 173), which is still moderate, but the surf quality is still described as very ordinary. You’ll get a few fun little waves, but don’t expect anything special.
Friday the 14th of August is where it gets interesting. The morning shows 4ft from the northwest, period 8 seconds, with glassy conditions. The combined energy hits 238 – that’s moderate energy, and the forecast says “expect good surf conditions.” This is your standout for the whole 16-day window. The swell direction is from the northwest, which is off the optimum west, but it’s still the best we’ve got. With glassy winds, it’ll be clean. At 4ft, it’s fine for beginners and intermediates alike. The water temperature is about average for this time of year, so no need to worry about a cold shock.
After Friday, the wind turns against us. Saturday the 15th and Sunday the 16th are still on the small side, with 4ft to 5ft, but the wind is cross-onshore, making it choppy and poor. The swell energy is up (290 on Sunday), but the quality drops. Monday the 17th is a write-off with strong cross-onshore winds.
We then have a gap of a few days with no real highlights. The swell picks up to 6ft on Wednesday the 19th, but it’s cross-onshore and the energy is high (443), making it look more like a kite-surfing day than a paddle session. At 7ft, it’s getting into the expert-only zone, but with poor conditions, it’s not worth it.
The very end of the forecast, on Sunday the 23rd of August, shows a clean cross-offshore wind with 4ft from the northwest, period 8 seconds, and moderate energy (198). It’s described as “clean” but with “surfable waves but very ordinary conditions.” It’s a maybe, but not a standout.
So, to wrap it up: the best bet is Friday morning, the 14th of August. 4ft from the northwest, glassy clean conditions, and decent energy. It’s not pumping, but it’s the pick of the run. The rest of the window is mostly small, choppy, or just plain ordinary. Keep your eyes on the forecast, but for now, that Friday is your day.
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.
