The Lowdown
Alright, this is Rusty. Let's be straight with you. The next couple of weeks at Whangamoa are looking pretty grim. This is a real flat spell, and honestly, from the end of July right through to the middle of August, there's just nothing to get excited about. We're looking at a solid 12 or 13 days of very little to no surfable waves. It's a long dry run, but that's how it goes sometimes in this game.
The first real glimmer of hope doesn't show up until Thursday the 6th of August. There's a bit of life in the water by the afternoon, with a 5ft swell from the north pushing in. The period is short at 7 seconds, so it won't be the most powerful, but the wind is looking glassy—dead calm. That combination of clean conditions and a bit of size makes it a standout for this period. The combined wave energy is moderate at 215, so there's some juice there. Early morning on Friday the 7th is also looking solid, with a 6ft NNW swell—that's getting into the size where it's for the more experienced surfers, over 5ft—and the combined energy jumps way up to 486. The wind is glassy again, which is just perfect. The period is still short at 8 seconds, but the clean, glassy conditions will make it feel better than it is. Friday afternoon follows up with a clean 6ft set.
So, if you're holding out, mark your calendar for Thursday afternoon, August 6th, and especially Friday, August 7th. That's the only real window with any punch. The rest of the week into the 15th looks like a complete write-off.
Rusty.

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.
