The Lowdown

Alright, let’s be straight with you. The next couple of weeks at Polihale are looking pretty grim for paddle surfing. To be honest, there’s nothing that’s really going to get the stoke levels up. We’ve got a long, dry run of flat days and tiny, weak swell coming in. The first real sniff of anything starts around the 15th of August, but even then, it’s a real struggle. For a solid week before that, from the 6th through to the 14th, it’s just flat to knee-high slop with no energy to speak of. The combined swell energy is basically zero (0) for most of those days. The water temp is sitting around 81°, which is pretty average for this time of year, so at least it’s warm for a paddle.
Now, the first bit of swell that shows any life at all will be on Saturday morning, the 15th. We’re looking at a 2ft swell from the West, with a 13-second period giving it a bit of a pulse. The combined energy is 88 (weak), which is better than nothing, but it’s still very ordinary. The cross-offshore wind from the ENE will keep the surface clean, but it’s just not going to be a memorable session. This is more of a "get the cobwebs out" kind of day.
The action picks up a little on Monday the 17th. The swell goes up to 2ft from the West, with a 13-second period, and the combined energy climbs to 126 (moderate). The problem is that the wind goes cross-shore from the NE, and it’s not a clean offshore. It’s going to chop things up a bit. This is a better wave than the weekend, but the wind is going to mess with the quality.
The most interesting day in the whole forecast is Thursday the 20th. The afternoon brings a 2ft swell from the SW, but look at the period: 21 seconds. That’s a very long period groundswell. The combined energy jumps to 251 (moderate). The wind is light and cross-offshore from the East, which will keep the surface clean. This is the standout. Polihale is a sandbar, so with a very long period swell like this, it might be a bit too straight, but the energy and the clean conditions make it the best bet for a sneaky session.
After that, it fades right back down. The rest of the window is a write-off for decent surf. Honestly, if you’re desperate for a paddle, the 15th is your best bet, but don’t get your hopes up. The 20th is the one to watch, but it’s a long way off.

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