The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming down the line for us at Lake Ferry.
Straight up, we’ve got a mixed bag over the next couple of weeks. The start of the period is a write-off for any decent paddle surfing. Monday the 17th through Tuesday the 18th serve up big, raw, onshore-chopped-up slop. The combined energy reading is huge, up to 4906 (moderate to strong), but with the wind howling straight onshore at 19 mph, it’s just a mess. Not our day.
Wednesday the 19th actually has some proper size – we’re talking 13 ft swell from the S and 12 ft from the S – and the wind is light onshore, but the forecast notes it’s just too big for this sandbar setup. Unless you’re a true expert and like getting pounded, I’d give it a miss.
Now, Thursday the 20th is where we get our first real stand-out. It’s glassy – dead glassy – with a light 3 mph SW wind. The swell drops to a much more manageable 6 ft from the S, with a moderate 825 combined energy. The period is 12 seconds, which gives it some decent push and shape. This is your best bet for clean, fun waves in the near term. The water temp is 52°, which is a bit colder than normal for the time of year, so a thick wetsuit is a must. Crowds can pop up here sometimes, so get there early.
From there, things get dicey again. Friday the 21st through Monday the 24th is a stretch of clean but weak, marginal surf as the swell drops away and strong cross-offshore winds mess with the shape. The combined energy drops to as low as 39 (weak energy) on the 23rd. That’s a gap of several days where you’re really not missing much.
Looking ahead to the second week, there’s a promising but less certain window on Friday the 28th of August. The morning shows 6 ft from the SSW, with a 14-second period and a light 9 mph offshore wind from the N. Combined energy is a solid 1393 (moderate). The notes say it’s excellent for experienced surfers. That’s the one to circle on the calendar. Saturday the 29th also has some good fun-sized options, with 6 ft SSW and clean conditions, but the 28th is the pick.
The end of the month and into September looks on-and-off with average to poor conditions and building onshore wind again, so don’t get your hopes up for that last stretch.
So, bottom line: Thursday the 20th is your best early call for clean, glassy chest-to-head-high surf. And if you can wait, Friday the 28th of August morning looks like the pick of the longer range for a bigger, cleaner, offshore swell.
Stay salty.

Information about the Lake Ferry Surf forecast
The above surf forecast table for Lake Ferry provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lake Ferry can be found by selecting the local surf guide option on the grey menu. Our Lake Ferry 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 (Lake Ferry) 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 Lake Ferry 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.
Lake Ferry is 28 km (17 miles) from Lower Hutt. If you plan a holiday in The Wairarapa, look for hotels and other accommodation in Lower Hutt. Lower Hutt has rooms for a wide range of budgets as well as car hire and transport links.
