Alright, Rusty here. Let’s chew the fat on what’s happening down at Kalapaki Beach for the next couple of weeks.

Straight up, this is a tough forecast to swallow. The first ten or eleven days are a write-off for any kind of quality surf. The wind is just relentless, blowing cross-onshore or cross-shore from the ENE most of the time, and it’s chopping up what little wave energy we get. The combined swell energy is mostly in that moderate zone, bouncing around the 400 to 800 mark, but with poor to marginal conditions tagged on every session. From July 12th all the way through to about July 22nd, I wouldn't bother dragging your board out. The setup looks way more interesting for a kite surfer than a paddler, with those steady winds and short-period windswell.

For the first few days, starting Sunday the 12th, we have rain showers and an ENE breeze at 15 mph blowing cross-on. The swell is a messy 7 ft but with a short period of just 7 seconds – a proper windswell that's all bump and no push. Monday the 13th and Tuesday the 14th don’t get any better either.

Water temp here at Kalapaki is a warm 79°F, right about average for this time of year, so at least you won't be cold while you're getting frustrated.

The only glimmer of hope, and I mean the *only* standout across this whole 16-day run, shows up on Sunday, July 26th and Monday, July 27th. It’s a long way off, so treat it with caution, but the models are trying to line something up. We finally get a proper long-period groundswell from the East with a period of 15 seconds. On Sunday afternoon, the combined energy hits a strong 1034 – the biggest number in the whole forecast. The swell sits at a fun 3 ft, and while the wind is still cross-shore from the ENE at 12-15 mph, it’s not onshore, so it can work. For a reef setup like Kalapaki, that long period from the East will wrap in nicely, even if the optimum swell is from the SSE. Just be prepared for a crowd – this spot can get busy, especially when a window finally opens up.

The days before that, from July 22nd to 25th, are tiny south swells with a side-shore breeze that just can’t make a silk purse out of a sow’s ear. No dice.

So here’s the take: for the next week and a half, leave the board at home. The only reason to get excited, and it's a *maybe*, is that window on July 26th and 27th when that East groundswell hits. It’s the best of a bad bunch, but keep an eye on it.

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.
