The Lowdown
Alright, folks. Rusty here. Let’s get into it.
We’ve got a solid run of surf coming up at Waiwakaiho, starting with a bit of a slow one on Wednesday afternoon. The waves are small, only about 2ft from the WSW with a very long 16-second period, but the wind is a messy cross-off from the ENE at 18 mph. The combined energy is weak (258), so it’s not really worth paddling out for. Better to wait.
Thursday morning is where it starts to pick up. The swell jumps to 4ft from the WNW, period drops to 10 seconds, and the wind is a light cross-off from the ENE at 6 mph. It’s clean, and the energy is moderate (385). This is a decent window for a session. Thursday afternoon sees the swell push to 5ft from the WNW with a 12-second period, but a cross-on wind from the NNE at 3 mph puts a slight ripple on it. The energy is strong (1045), but it’s not the best quality.
Now, Friday morning is a real standout. The swell is 4ft from the WSW, period is a long 16 seconds, and we’ve got offshore wind from the SE at 6 mph. It’s clean. The energy is strong (1035). This is a quality session for intermediates. The water temp is 57°, which is about average for this time of year.
Saturday is the big one for experienced surfers. Morning and afternoon both deliver 7ft to 7ft swell from the WSW with a 17 to 16-second period. The wind is light cross-off from the SSW, clean. The energy is very strong (2351 and 2627). This is big, powerful, long-period groundswell. It’s going to be breaking a bit straight at the beach, but for the crew who know what they’re doing, it’s a ripper. Sunday holds similar size (7ft to 8ft) with clean offshore winds from the SSE, but the energy is still very strong (2728 and 2347). More excellent conditions for the experienced.
Monday through Wednesday next week settles back to more manageable 5ft to 5ft swell from the WSW, with mostly clean conditions and light winds, including a glassy morning on Wednesday the 19th. The energy is moderate to strong (754 to 1252). Good, consistent waves for the intermediate crew.
The second week sees a drop in quality. Thursday the 20th has a clean 5ft morning, but the wind goes onshore in the afternoon. Friday the 21st is small and glassy in the morning but onshore later. The weekend of the 22nd and 23rd is small and weak, with energy dropping below 400. Not worth the effort.
Then we get a pulse again on Monday the 24th with a 6ft swell from the W, but the wind is a messy cross, and the period is short (10 seconds). The energy is moderate (876). Tuesday the 25th brings a bigger 8ft swell from the WNW with a clean cross-off wind, but the period is short (10 seconds). The energy is very strong (2767). Wednesday the 26th is messy and onshore, with 12ft waves but poor conditions.
The real standout in the second week is Thursday the 27th. We’ve got an 8ft swell from the W with a 14-second period and clean offshore wind from the SE. The energy is very strong (2073). This is for experts only, but it’s a promising window. Keep an eye on it.
Rusty.

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