The Lowdown
Alright, let’s have a look at what’s on offer here at Miramar. It’s a beach and reef set-up that’s exposed to the west. The water temp is about average for this time of year, nothing too unusual.
Right now, we’re looking at a bit of a slow start. Wednesday the 26th and Thursday the 27th are basically write-offs. We’ve got rain and thunderstorms, wind is all over the place, and the swell is small and junky. Not worth paddling out.
Friday the 28th is where things start to get interesting. The morning looks best with a clean 6ft swell from the west-northwest, period bumping up to 11 seconds, and combined wave energy sitting at a moderate 631. The wind is cross-shore, so it’s not perfect, but it’s surfable. That afternoon, the wind turns cross-on and the energy drops off a bit.
Saturday the 29th is pretty flat and messy. Sunday the 30th, though – that’s the standout. Early morning is glassy, with the wind dead calm. Swell is a clean 4ft from the west-northwest, period at 11 seconds, and energy at 382. Conditions are set to be good. This is the one you want to aim for. The afternoon gets a bit choppy as the wind picks up, so get out there early.
Monday the 31st and Tuesday the 1st of September are marginal. The swell holds around 4 to 5ft from the northwest, but the wind is cross-shore and light, which keeps things just okay, not great. Afternoon sessions are a no-go.
Wednesday the 2nd of September has a clean morning with cross-offshore wind and a small 4ft swell, but the period is short at 7 seconds, so the waves will be a bit weak. Thursday the 3rd has another glassy start – 4ft swell, clean, but nothing special.
From Friday the 4th through to Sunday the 6th of September, the swell drops off to around 3ft to 3ft. There are some glassy moments, especially on Sunday the 6th morning with no wind and a 3ft swell from the west-northwest, period 9 seconds, and energy at 236. It’s small but clean.
Monday the 7th of September is marginal again. But then Tuesday the 8th of September morning – this is another real highlight. Glassy conditions, 5ft swell from the northwest, period 9 seconds, combined energy at 379. This is a solid, clean session. The afternoon gets cross-on and messy.
After that, Wednesday the 9th and Thursday the 10th of September are small and ordinary. The swell drops to 4ft and then 2ft, with light winds but nothing that gets the heart pumping.
So, the best on offer here is Sunday the 30th of August morning for that glassy, clean 4ft swell, and Tuesday the 8th of September morning for a bit more size at 5ft also glassy. Get on those.

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.
