The Lowdown

G’day, it’s Rusty here. Let’s be straight with you: the next couple of weeks at Mona Vale Beach aren’t exactly firing. We’ve got a long stretch of small, weak swells and a whole lot of ordinary conditions. The first real surfable waves don’t show up until Sunday the 9th, and even then, it’s pretty marginal. There’s a decent window of energy around Monday the 10th, but the wind’s going to be howling, so it won’t be pretty. After that, it drops right back off again until we get a late burst of something on Friday the 21st, though that one looks messy.

Here’s the rundown. From now through Saturday the 8th, it’s flat out. You’re looking at knee-high leftovers at best, with light winds but no push. Don’t bother waxing up. The first sniff of anything is Sunday morning the 9th. The swell bumps up to around 3 ft from the ENE with a 9-second period, and while the combined energy is moderate at 158, the onshore northerly breeze keeps it clean-ish but pretty ordinary. It’s surfable, but you won’t be telling your mates about it.

Monday the 10th is the peak of the run. The swell hits 5 ft in the morning from the ENE, again with a 9-second period, and the energy jumps to a strong 392. But here’s the catch: it’s blowing a 25 mph WNW cross-offshore. That’s going to trash the surface. By afternoon, the swell drops back to 3 ft and the wind swings west at 19 mph, still cross-off, but the damage is done. It’s grunty but ugly. A beach break like this with that much wind and swell? Honestly, the kites are going to have more fun than the paddle crew.

From Tuesday the 11th right through to Thursday the 20th, it’s a wasteland. Swell stays small, mostly 1.0 ft to 2 ft, with energy readings mostly in the weak to low-moderate range. There are a few mornings with lighter winds and clean surfaces, but there’s just no swell to ride. It’s a long, flat spell, mate. The only notable thing is a brief pulse of 2 ft on the 12th with a fresh offshore breeze, but even then, there’s nothing behind it.

Then, on Friday the 21st, we get a late tease. The morning has a 2 ft ENE swell, and it’s clean with light winds. Surfable, but still tiny. The afternoon, though, is where it gets interesting – and not in a good way. A new south swell arrives at 6 ft but with a short, crumbly 6-second period. The energy is strong at 300, but the wind swings onshore from the ESE, creating a mess. It’s a short-period windswell on a beach break, so expect bumpy, closeout waves. You’d need to be an expert, or just a glutton for punishment, to even bother paddling out.

So, bottom line: the best of the whole window is probably Monday morning the 10th, but it’s a howling mess. Otherwise, keep the board in the car and wait for the next system. The water temp is sitting at 64°, which is about normal for this time of year, so the wetsuit’s fine. It’s a rough stretch, but that’s the beach for you. Forecasts can change, but right now, I’d be finding other things to do for a while.

Rusty out.

Information about the Mona Vale Beach Surf forecast

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