The Lowdown
Alright, Rusty here. Let's talk about what's on offer at Miramar over the next couple of weeks.
First up, it's been a bit quiet, but we've got a decent little window kicking off this Sunday, August 23rd. The morning is looking good with a clean 5ft swell from the west. The wind is glassy, coming in light from the ESE at just 3 mph, so the surface will be nice and smooth. There's a solid 424 units of energy in the water (moderate), and with a 10-second period, it'll have a bit of push. This is your best chance for a fun session in the short term. The water temp is about average for this time of year, so no surprises there. It's a beginner-friendly break, but those conditions will make it a treat for anyone.
Later that Sunday afternoon, the wind picks up to 12 mph from the ESE, turning it cross-offshore and keeping things clean, but the wave size drops a touch to 4ft. It's still surfable, but the morning is the standout.
Monday the 24th brings in stronger winds from the SSE at 22 mph, which will mess things up. The swell jumps to 5ft from the SW, but with that wind, it’s going to be a write-off. The rest of the week into the weekend is pretty average. Tuesday and Wednesday have small, weak swells and cross-shore or onshore winds, so you’re better off doing something else.
We do see a bit of a pulse building towards Friday the 28th. The morning has a 6ft swell from the WNW with a 10-second period and a light 6 mph S wind creating a cross-shore breeze. That's a lot of energy (806 units), but the wind direction isn't perfect, so it might be a bit lumpy. It's a marginal call. The afternoon gets interesting with a 7ft swell from the WNW, a long 11-second period, and light offshore W winds at 6 mph. This is the biggest, cleanest window of the whole period, but with a 7ft swell, this is more for the experienced crew. It's a point break and reef setup, so that long period should line up nicely. This is the other standout, but it’s a week out, so keep an eye on it.
After that, the swell drops right off. Saturday the 29th morning is clean with a 4ft WNW swell and a light offshore NNE breeze, but it's short-lived as the wind swings onshore in the afternoon. The rest of the first week of September is dominated by small, weak swells (under 3ft) and mostly poor winds. There's a long gap from the 29th of August all the way through to the end of the forecast with nothing really worth paddling out for. It's a flat spell, plain and simple.
So, to sum it up: your best bet is Sunday morning, August 23rd, for clean, fun waves. The other one to watch is Friday afternoon, August 28th, for the biggest, cleanest swell of the period, but it's for experienced surfers only.

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.
