The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for your local stretch.
Right off the bat, we've got a bit of a waiting game on our hands. The first few days are pretty ordinary, so don't get too excited just yet. The ocean is feeling the effects of a water temperature anomaly that's 2° warmer than usual for this time of year, which is definitely notable. You'll feel that in the water.
For Monday afternoon, it's a bit of a write-off at Miramar (beach/jetty). We've got a 4ft SSE swell running, but it's coming in with a cross-on shore breeze, and the combined energy is only moderate (380). The call is marginal at best.
Tuesday morning shows a bit of promise. The swell drops to 3ft from the SE with a 10-second period, and the wind swings to a light cross-offshore from the NNE. The energy is still moderate (227), but the conditions will be clean. It's surfable, but nothing to write home about. Tuesday afternoon sees the wind pick up, making it a bit more ordinary.
Wednesday morning is the first real highlight of the run. We've got a clean 2ft swell from the SE with a 9-second period, and the wind is blowing offshore from the NW. The combined energy is weak (122), but it's clean, and it's a good chance for a paddle if you're jonesing. The conditions look clean.
Now, here's where it gets interesting. We have a big gap of poor conditions from Wednesday afternoon all the way through to the end of the first week. The wind gets nasty, and the swell direction goes all over the shop. Then, on Friday the 7th of August, the ocean wakes up. A big 10ft S swell rolls in, with a massive energy reading of 1533, but the wind is screaming from the WSW at 31 mph. This is a full-on, expert-only situation. The setup is more interesting for kite surfing than paddle surfing. Saturday and Sunday follow a similar pattern with big, clean but wind-affected swell.
The real standout, the one to circle on your calendar, is the morning of Tuesday the 11th of August. This is where it all comes together. The swell is a solid 5ft from the SSE with an 11-second period, giving it a moderate energy (722). But the magic is in the wind: it's glassy. Dead flat. A WNW breeze at just 3 mph. This is the best on offer. The water will be like a lake, and the sets will be clean and lined up. It's a consistent spot, so you'll get waves, but with conditions this good, expect crowds here.
The rest of the second week is a bit of a mixed bag, with only a few windows of clean but smaller swell. The morning of Wednesday the 12th of August has a clean 3ft SE swell, and the following Thursday morning the 13th of August has a clean 3ft SSE swell. Both are decent for a fun session, but not the standout of the 11th. The last few days of the outlook are a write-off, with strong onshores and tiny, weak swell.
So, to wrap it up: Wait for that Tuesday morning glass-off on the 11th of August. That's your winner.
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.
