The Lowdown
Alright, Rusty here, checking in on the Boulders forecast.
The next few days are looking pretty grim, but if you've got the patience of a saint, there's a nugget of gold at the end.
Your one and only window this week is Monday afternoon, the 27th. We've got a light cross-off breeze from the NE at 6 mph, keeping the surface glassy. There's a 5ft SSE swell with a long 12-second period, so it's got some grunt. The water is a warm 81°, which is about right for this time of year. The wave energy is moderate (943), but it's going to be fun. That's your best bet for a surf.
After that, it's a total shutout. From Tuesday the 28th, a strong SE wind blows in and just kills the quality. The swell stays in the mix, but the wind is a constant cross-on mess. The forecast shows poor conditions all the way through to Sunday the 9th of August. The wind is mostly fresh to strong, from the SE, turning the ocean into a lumpy, choppy mess. There are a couple of days with bigger swell, like an 8ft wave on the 5th of August, but with 25 mph SE winds, it's a total washout and way more interesting for kite-surfing than for us.
Hang in there, because the second week is looking much better. The 10th of August is a glimmer of hope. Monday morning shows a moderate offshore wind from the NNW at 16 mph, paired with a 4ft SW groundswell running a long 16-second period. The energy is strong (1534), and that offshore wind should clean it right up. It's a long way out, so keep your fingers crossed.
But the real treasure is the morning of Tuesday the 11th of August. The forecast is calling for glassy conditions, with a light SE breeze at only 3 mph. The swell is a solid 6ft from the SSW, packing a very long 15-second period and a massive (2352) energy reading. That's a serious groundswell, and with glassy conditions, it's going to be a dream for experienced surfers. Just remember, a long-period swell like that can be a bit tricky at a beach break, but on a reef like Boulders, it's going to be lined up beautifully. This is a long-range tip, so treat it with a little caution, but it's the one to circle.
Boulders is a consistent spot, but it can get crowded sometimes. If you head out for that Tuesday morning session, get there early.
Rusty.

Information about the Boulders Surf forecast
The above surf forecast table for Boulders provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Boulders can be found by selecting the local surf guide option on the grey menu. Our Boulders 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 (Boulders) 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 Boulders 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.
