The Lowdown
Alright crew, Rusty here. Let's break down what's cookin' for the next couple weeks.
It's lookin' pretty bleak out at Whangamoa sandbar. We're talking a big ol' stretch of flat or junk surf right from the start. The first real hope doesn't show up until Saturday, August 1st.
The one to circle on the calendar is the morning of Saturday, August 1st. We've got a 2ft swell coming from the NW with a long 14-second period – that's some proper groundswell, packing moderate energy (287). The wind is the real hero though: clean offshore from the SSE at just 3 mph. It's gonna be glassy and lined up. The water temp is 55°F, which is dead average for this time of year. This is your window, plain and simple. Remember, this spot is inconsistent, so when it turns on, it's a gem.
The afternoon of the same day goes glassy, but the swell drops to 2ft from the NNW with a short 8-second period. It'll be weak and a bit jumbled – not worth rushing for.
After that, it's back to the doldrums. The 2nd, 3rd, 4th, and 5th are all flat or tiny dribbles with hardly any energy (energy values of 25 or lower). The 6th and 7th are the same story: poor surf, no size. We get a tiny 0.7ft, 19-second groundswell on the morning of the 8th, but with only 37 energy, it's barely a ripple. The 9th morning shows a 0.7ft, 17-second swell and 46 energy, but it's still just a very ordinary wave, nothin' special.
From the 10th onward, it's flat. Energy values are down to 1 or 0. Another long gap of nothing. The second week is a write-off. If you're gonna paddle out, make it the morning of the 1st – that's your only real shot.

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