The Lowdown
Alright folks, Rusty here with a look at the waves on offer. We’ve got a stretch of mostly average to poor conditions at Miramar, but there are a couple of real standouts if you’re patient.
The overall pattern is messy. For the first few days, we’re dealing with wind that’s ruining what little swell there is. A big gap of poor surf runs from Monday the 14th through Wednesday the 16th. Nothing to even think about paddling out for.
Thursday the 17th morning finally shows a bit of life. Swell is 5ft from the NW with a period of 10 seconds, and the wind is a clean cross-offshore. The combined energy is moderate (520). It’s not a huge swell, but with that clean wind, it’s a solid option for a session.
The real standout is Saturday the 19th morning. Clear skies, a light easterly offshore at 6 mph, and a 6ft NW swell with a 14-second period. That’s a proper groundswell with some punch behind it. The wave energy is getting strong (1036). This is excellent surf for experienced surfers, though at 6ft it’s getting a bit spicy for beginners, especially with those longer gaps between sets. It’ll be clean and organised.
Sunday the 20th morning is a good follow-up with a 4ft NW swell, a light offshore wind, and clean conditions. Easy combo.
We get another chance on Saturday the 27th morning. A glassy, 6ft WNW swell with an 11-second period, and very strong combined energy (936). That’s another excellent window for experienced crew. The water temp is 64°, which is about 2° cooler than average for this time of year.
Keep in mind that Miramar is a beach and reef setup, so when that long-period swell is running on the 19th, it might be breaking a bit straight on the beach, so look for the reef sections.
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.
