The Lowdown

Alright folks, Rusty here. Let’s talk about Tainohama.

It’s a pretty quiet start to the outlook. For the first several days, we’re looking at tiny, weak waves with hardly any push. The combined swell energy is weak, in the double digits (86), and really only Wednesday morning offers a glimpse of something surfable, with a tiny 2ft SE swell under glassy conditions. The water is a touch warmer than normal for the time of year at 83°, so no need for a thick wetsuit. But honestly, from Wednesday afternoon right through to Saturday the 1st of August, it’s all poor surf conditions or flat spells. There’s a real gap of nothing worthwhile here.

Things start to flicker to life on Sunday the 2nd of August. The morning still looks small and weak, but by the afternoon, a long-period 3ft ESE swell rolls in with moderate energy (343), though it’s onshore wind so don’t expect perfection. The real build-up kicks off Monday the 3rd. Swell jumps to 6ft in the morning with a very long 17-second period, and energy is strong (1626). It’s still onshore, so quality is marginal, and the 7ft afternoon pulse gets even bigger but wind stays messy. This is shaping up as a pulse for experienced surfers only.

The standout window is Tuesday the 4th and into Wednesday the 5th. On Tuesday morning, look for a solid 10ft ESE groundswell with an 18-second period. That’s a very long period from the optimum direction for Tainohama, meaning the reef will handle it beautifully. The combined energy is well into strong territory (5242). There’s a risk of thunderstorms, and it’s onshore wind, so that’s a caveat, but the size and quality of the swell, coupled with the fact that it matches the break’s ideal direction, make this the best on offer for the whole run. Wednesday the 5th goes massive, with peak afternoon swell pushing 23ft SE and extreme energy (32430). However, the forecast notes the swell is too big for this reef break, even with favorable cross-offshore winds from the NNE. That’s a big wave day that only the most expert chargers should even consider, and even then, it may be unruly.

From there, the pulse fades through Thursday the 6th and Friday the 7th, with still-big swell but strong cross-shore winds creating lumpy, messy conditions. By the weekend, we’re back down to poor surf on most days. There’s a flicker on the 13th of August with a 13ft ESE groundswell under clean, cross-offshore wind – another option for experienced surfers, but it’s far out and less certain.

All in all, the true highlight is Tuesday the 4th of August morning. That 10ft, 18-second ESE groundswell from the optimum direction gives Tainohama some serious potential, despite the onshore wind and storm risk. If you can handle the size, it’s the session to aim for.

Rusty.

Information about the Tainohama Surf forecast

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