Alright folks, Rusty here. Let’s break down what’s coming for Tainohama over the next couple of weeks.
The water is sitting at 77° – pretty normal for the time of year, so nothing weird going on with the temp. But the first few days are a total bust. Sunday and Monday mornings are flat and choppy, with onshore wind and weak swell. Not worth paddling out. Then Monday afternoon (July 6th) the wind goes glassy and we get a 3ft SE groundswell with a 14-second period. Energy is moderate at 369. It’s not huge, but the clean surface will give you a few fun ones if you’re itching.
Tuesday July 7th morning is the first real highlight. Offshore wind from the NE, barely a breath, and 4ft of SE swell with a 12-second period. The combined energy hits 759. The reef will be working with smooth, lined-up sets between lulls. This break is consistent and exposed to that direction, but it’s advanced-only. Crowds are just sometimes, so you won’t be fighting for waves, but there’ll be a few others.
Then the big stuff rolls in. Friday July 10th morning – we’re talking 13ft of S swell with a 17-second period. That’s massive, very long period groundswell. Energy is an insane 10206. This is purely for experts. The wind is light cross-onshore, not perfect, but the power is enormous. Because it’s such a long period and a reef setup, expect heavy, dredging waves. Saturday July 11th keeps the size around 12ft to 13ft from the SSW. Still only for the hardcore crew.
Sunday July 12th morning is where things settle into a more manageable size. We’ve got 7ft from the SSW with a 14-second period and glassy conditions. Energy is still solid at 1841, but with no wind, this will be clean, lined-up reef riding. This is the best day for strong intermediate to advanced surfers who don’t want to get smoked.
After that, the swell drops fast. From Monday July 13th onward, we’re under 5ft with mostly onshore or cross-onshore breeze and short period junk. One small bright spot: Thursday July 16th morning is glassy with a 3ft ESE swell and an 11-second period. Not powerful, but clean for a small-wave board.
So, to sum it up – the standout days are Friday July 10th through Sunday July 12th. Experts, go Friday or Saturday for the biggest, most powerful waves. For everyone else, Sunday July 12th morning with glassy conditions and 7ft is the one 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.
