Alright folks, Rusty here. Let's be straight up – the next couple of weeks are a bit of a write-off for a proper surf at this spot. We've got one break on the radar, Chinamans Hat/Mokolii, but the conditions are just not playing ball. The water temp is sitting at a very typical 79°, which feels normal for this time of year.

Things kick off on Friday afternoon, the 3rd of July, with a 6 ft swell from the ENE, but that’s coming with a stiff 16 mph cross-onshore wind. The period is a short, weak 8 seconds, and the combined energy is in the moderate range at 376. It’s gonna be choppy and bumpy, to be honest.

Saturday the 4th into Sunday the 5th is more of the same: 6 ft to 6 ft ENE swell with that nagging cross-on breeze. The period drops to a sloppy 7 seconds over the weekend, so the waves will be weak and messy.

Monday the 6th sees a bit more size, pushing 7 ft to 7 ft, and the energy bumps up to a solid 544, but the wind kicks up to 19 mph. It's going to be a lumpy mess – frankly, this setup looks more interesting for kite surfing than paddle surfing. Too blown out and short-period to be any fun on a log or a shortboard.

We’ve got a solid two-week stretch of this. From the 7th of July all the way through to the 18th of July, the swell hangs around between 4 ft and 7 ft, but it's constantly from the ENE, which is the cross-on direction for this spot. The wind never really lets up, staying cross-on or cross-shore. The period stays stubbornly at 6 to 8 seconds for the whole run, so you're getting short, weak, wind-affected lumps. The combined energy fluctuates between 173 and 497, which is weak to moderate at best.

This break is already inconsistent, so with these poor conditions across the board, there isn't a single standout day in the entire 16-day window. It’s a blank run, plain and simple. Keep the board in the car and your eyes on the forecast – it can’t stay like this forever.

Rusty.

A general guide to surfing at Chinamans Hat/Mokolii can be found by selecting the local surf guide option on the grey menu. Our Chinamans Hat/Mokolii 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.

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 Chinamans Hat/Mokolii 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.
