The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer.
Right off the bat, the next couple of weeks are looking pretty average for surfing around here. The swell is small and most of the time the wind is not playing nice. There’s a bit of a wait for the best conditions, but we’ll get to that.
The first real chance to get wet is Tuesday morning, the 11th of August. Miramar (beach and reef) will see a tiny 2ft NW swell, with a period of just 6 seconds – that’s short-period windswell, not much grunt. The combined energy is weak (60). The big plus here is the wind: it’s glassy from the WNW. The water is a very notable 71°F, which is much warmer than normal for this time of year. It’s a beginner-friendly spot, but don’t expect anything special.
Wednesday morning, the 12th, is a similar story. The swell bumps up just a little to 3ft from the W, with a period of 9 seconds. The combined energy is moderate (136). The wind is glassy again from the W. This is the pick of the early week, with clean, small waves. It’s surfable, but ordinary.
Thursday the 13th through Monday the 18th is a write-off. The wind is cross-shore or cross-onshore every session, with speeds picking up. The swell hangs around 4ft to 6ft, but the quality is poor. It’s choppy and messy. Nothing to get excited about.
The next worthwhile window doesn’t arrive until Friday morning, the 21st of August. We get a glassy morning with the wind calm from the SW. The swell is a tiny 2ft from the WNW, with a period of 9 seconds and combined energy of just 85. It’s barely surfable, but it’s clean.
The standout session in the whole 16-day window is Saturday morning, the 22nd of August. The swell is still only 2ft, but it’s from the NW with a period of 12 seconds – that’s a proper groundswell. The combined energy is moderate (212). The wind is cross-shore from the NNW at 12 mph, which will keep the surface a bit bumpy, but the long period will give the waves some shape. This is the best-looking groundswell pulse we see, and for a spot like Miramar, that long period will help it wrap in better. Keep an eye on this one as a promising option, but it’s a week and a half away, so stay loose.
After that, it’s back to poor conditions through to the end of the forecast. Crowds are possible at Miramar, but with this quality, it’s unlikely to be busy.
Stay patient, and keep an eye on the wind.
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.
