The Lowdown

Alright, let's get into it. The next couple of weeks at Miramar are a bit of a mixed bag, a real tale of two weeks to be honest. The surf's gonna be there, but it's not gonna be handed to you on a plate. We're looking at a period that starts off pretty messy, cleans up a touch, then fades away before a possible little pulse at the tail end of the forecast. Let's break it down.

First up, this weekend. Saturday the 29th starts off with a bit of hope. The morning is glassy, with a 4ft WNW swell showing 184 units of energy. It's surfable, but it's nothing to write home about. The afternoon, though, the onshore kicks in and it just gets messy. Sunday the 30th is much the same story; a bit of swell but the cross-onshore wind chops it all up. You're looking at poor conditions both days, so unless you're desperate, maybe give it a miss.

Monday the 31st and Tuesday the 1st follow a similar pattern. We see a bit more energy in the water, up to 438 units on Monday afternoon with a 5ft NW swell, but that onshore wind just wrecks it. Light cross-shore winds in the mornings give you a glimmer of hope, but the forecast just says "marginal" at best. It's gonna be a grind.

Then the swell backs off. Wednesday and Thursday, the 2nd and 3rd, we're down to 3-4ft with the period dropping to 7 seconds. This is short-period, windswell stuff. Energy drops to the low 100s, even down to 97 units on Thursday morning. It’s small and weak, just not doing anything for us. By Friday the 4th and Saturday the 5th, we're still stuck in that 3ft range. Saturday morning offers a clean, cross-off wind which is a plus, but the swell is just too small and weak to get excited about.

Now, here’s where things get a little more interesting. Sunday the 6th of September is the standout. The afternoon session looks the goods. We’ve got a 4ft NW swell with a 10-second period, and the wind is a light cross-off, making it clean. The energy is a moderate 204 units, but the conditions are right. This is your best bet for a proper surf in the first week. We also see the water temp at 66°, which is about normal for this time of year, so the 3/2 will do.

Monday the 7th is back to the grind with a cross-shore in the morning and howling onshore in the afternoon. But then, look at this: Tuesday the 8th and Wednesday the 9th of September. Both mornings are glassy with clean 3ft to 4ft surf coming from the WNW and NW. Energy is moderate, over 200 units, and the conditions are described as "good". These are your mornings to get out there before the sea breeze messes it up.

After that, the wheels fall off. From Thursday the 10th all the way through to the end of the window on the 13th, we see the swell dying. Sizes drop to 1ft to 2ft. The energy just fades out, hitting as low as 33 units on the afternoon of the 11th. The period is all over the shop too. The only small glimmer is the morning of the 13th, where a 2ft, 14-second period groundswell shows some life, but it's too small to do anything. Honestly, that stretch from the 10th to the 13th is a dead zone, and you might be better off with the kiteboard.

So, to wrap it up: your best windows are the Sunday the 6th afternoon and the Tuesday and Wednesday mornings of the 8th and 9th. The long-range stuff at the end is promising but about as certain as a lottery ticket. It’s a fickle fortnight, but there are waves if you pick your moments.

Stay stoked.

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.
