Alright, Rusty here. Let’s break down what's headed for Wainui Beach - Stockroute.

Water temp is 57°F — that's about 2°F cooler than average for this time of year, so you'll feel the bite on that first duck dive.

We kick off with a sweet window Saturday morning, July 4th. Swell is 4 ft from the east with a 12-second period, giving it some real push. The combined energy is 453 (moderate), and the wind is clean cross-off from the NNW at 9 mph. This is the pick of the early weekend — clean, lined-up waves, but crowds can show up here sometimes.

Sunday morning is smaller at 4 ft from the east, light cross-off wind, but energy drops to 252 and the call is marginal. You'll scratch a few, but it's not a standout.

Monday gets messy. The swell jumps to 7 ft from the ENE on Monday morning, but the period drops to a short 8 seconds, and a cross-shore wind from the NNE at 12 mph makes for chop and lump. Not worth fighting.

Now, Tuesday, July 7th — that's the real gem. Glassy conditions both morning and afternoon, with the wind almost dead calm. Swell is 4 to 5 ft from the east, period at 10 seconds, and energy at 406 to 442. Clean, smooth surf. This is the best-looking day of the whole run for pure quality.

Wednesday morning keeps it good: 5 ft from the east, 10-second period, cross-off from the west at 6 mph, energy at 630. Excellent for an early session, but the wind shifts onshore later.

Thursday afternoon, July 9th, another good one: 5 ft from the ESE, light cross-off from the WSW, energy 541. Punchy and clean.

Then things get heavy. From Friday the 10th into the weekend, a big southerly swell hits. By Saturday, July 11th, it's 15 ft from the south with an 11-second period and energy at 6744 (strong). That's huge, and with strong cross-shore winds, it's not paddle-surf friendly. More of a kite-surfing session if anything.

Sunday the 12th is still massive at 12 ft — the forecast says it's too big for this break. Leave it for the absolute experts.

Monday, July 13th, drops to 8 ft from the south, cross-off from the west, energy 1512. This is the second standout: big, clean, powerful, but only for experienced surfers.

The second week tails off. Tuesday the 14th has a glassy morning with 4 ft from the SE, but a short 8-second period. Wednesday the 15th is small but clean at 3 ft. Thursday morning, July 16th, is interesting — a 15-second period groundswell from the SSE at 3 ft, energy 511, clean. That long period will wrap into the reef and point, but it's small.

From Friday the 17th on, the swell fades fast. By Saturday the 18th, it's down to 0.7 ft with a 17-second period — just a deep ocean pulse with no real surfable height.

The standouts are Saturday morning July 4th, Tuesday July 7th for the glassy goods, and Monday July 13th for the experienced crew looking for size and power.

Rusty.

Information about the Wainui Beach - Stockroute Surf forecast

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