Alright folks, Rusty here. Let's have a proper look at what's on the menu at The Core.

The pattern coming in is a bit of a rollercoaster. We start off with small, clean-ish waves through Tuesday but nothing to get too excited about. Then, come Wednesday, we see a big jump in size – a solid pulse of ESE groundswell with long, powerful periods around 16-17 seconds and moderate energy. The catch is, it's blowing cross-onshore and the conditions are marginal. Thursday morning, July 9th, is where it gets interesting. The swell holds at a hefty 12 ft from the ESE, with a very long 17 second period, and the wind swings clean offshore from the NE. The sheer energy in the water is massive. But here's the reality check: the swell is way too big for this break, especially for a beginner spot. This is purely for the experienced crew who know The Core's limits. It's a proper, heavy groundswell, so expect those long waits between sets but a lot of power when they come.

Later that day, the wind turns cross-onshore. Friday sees the swell peak at 19-23 ft, but with strong winds and rain, it's a write-off for normal surfing. Saturday morning, July 11th, has a weird one – it goes completely clean with a strong offshore from the SW, but the swell direction has switched to NE with a shorter 13 second period and the energy is still huge. Again, it's going to be a beast for experts only. The real standout for the average surfer is Saturday afternoon. The wind drops to near glassy, swinging offshore from the WSW at just 3 mph, and the swell settles to a much more manageable 6 ft from the E with a solid 12 second period. That's your cleanest window, and the report calls it excellent for experienced surfers. Saturday afternoon is the pick of the bunch by a long shot. Water temp is sitting at 83°, which is about normal for the time of year.

After Saturday, the surf drops off a cliff. Sunday the 12th we see tiny 2 ft waves with barely any energy, and then we enter a long, dry stretch. From Monday the 13th through to Wednesday the 22nd of July, it's mostly flat or tiny, poor quality surf. There's a slight bump around Thursday the 16th and Friday the 17th, with some 5-6 ft swell and cleaner conditions, but the energy is low and the wind stays messy. There's no real stand-out in that second week, just some marginal chances. If you're desperate, Saturday afternoon the 18th has a clean 4 ft E swell and light wind, but it's a long way out and not what I'd call a highlight.

So, in summary: the week starts small, builds to a massive, dangerous swell mid-week, gives us a golden window on Saturday afternoon the 11th, and then fades into a long, flat spell that could last a week or more. Don't hold your breath for the second week.

Rusty.

Information about the The Core Surf forecast

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