Alright folks, Rusty here. Let's take a look at what we've got coming up.

Honestly, for the next 16 days, it's a real tough stretch ahead. There are no good surf options on the table at all. We're looking at a long, blank run that is pretty normal for Kalapaki Beach when the trade winds just don't let up.

The whole pattern is dominated by a relentless ENE wind. It's not looking good. The rare bits of swell that pop up are all arriving with that same cross or cross-onshore breeze, just chopping everything up.

Right from the start, Monday the 6th of July, we're looking at a 7ft swell from the ENE, but it's a short-period 7 seconds and coming with a 19 mph cross-breeze. The combined energy is strong, reading 1019, but it's all lumpy cross-chop. The water temp is sitting at 79°, pretty normal for this time of year.

This pattern just keeps repeating. Tuesday the 7th has a little more size at 8ft from the ENE, but the period is still short at 8 seconds and the wind is fresh. It's not a wave you want to paddle out into. The energy actually drops into the hundreds, reading 900 for Tuesday afternoon, but the conditions are just poor.

For the rest of the first week and into the second, it's the same story. Swell sticks between 5ft and 7ft, always from the ENE or NE, always with a cross or cross-onshore wind. A few days, like the 14th, see the wind ease to a gentle breeze, but the swell is small, dropping to 4ft or 5ft, the period is short, and there's still a cross-chop messing it up.

There is a brief and very odd moment on the morning of Sunday the 12th of July. We see a tiny 3ft swell from the SSW with a very long period of 16 seconds. The energy is moderate at 413, but the wind is still cross-shore. For a reef like Kalapaki, a long-period SSW groundswell might wrap in, but with that wind and hardly any size, it's a no-go.

Later in the second week, around Tuesday the 21st of July, we see some very long-period energy from the E and S, with periods of 14 to 19 seconds and energy readings in the 400s and 600s. But the swell height is minuscule, between 2ft and 2ft. It's barely a ripple. The wind hasn't backed off either.

Bottom line: with the persistent wind and mostly short-period, cross-shore swell, this setup looks more interesting for kite surfing than paddle surfing. For a wave, you'd want to be looking elsewhere. Sometimes the forecast just changes, but right now, it's a washout.

Rusty.

Information about the Kalapaki Beach Surf forecast

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