The Lowdown
Alright, this is Rusty checking in with a look at what's coming our way for Miramar over the next couple of weeks.
Right off the bat, I gotta level with you—it’s a rough start. The first few days are looking pretty average to poor. It’s not until Sunday the 6th of September that we start to see a glimmer of something worth paddling out for. We’ve got a dry spell here for the first five days, so don't be in a rush.
The standout session, and the one I’d circle on the calendar, is Sunday morning the 6th of September. The wind is glassy, coming from the south at just 3.1 mph, and the ocean is calm. The swell is small, only 2.3 ft, but it’s coming from the northwest with a solid period of 12 seconds. That groundswell will have a nice shape, and the combined energy registers a moderate 248. The water is a touch warmer than normal for this time of year. It’s not going to be big, but it will be clean and fun for a beginner-friendly wave.
The next real highlight, and the best of the whole forecast, is Thursday morning the 10th of September. We’ve got a clean 4.6 ft northwest swell, glassy conditions with a light westerly breeze, and the wave energy is up to 319. The wind is from the west at just 3.1 mph, meaning it’s offshore for Miramar. This is your best bet for some proper, clean lines. The swell period is a bit short at 8 seconds, so it won't have the power of a groundswell, but that offshore wind will hold it up nicely.
After that, Friday morning the 11th also looks decent with another 5.2 ft northwest swell and glassy conditions, though it's a similar short-period swell. After the 12th, the swell really drops off and the consistency goes with it. Through the second week, there’s a few isolated mornings with glassy conditions and some small, longer-period groundswell, like on Monday the 14th of September, but the size is puny. The surf just peters out. If you’re a beginner, the early mornings of the 10th and 11th are your window. For everyone else, hope those forecasts change.
That’s the story from here. Stay frothy.

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.
