The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way.
Honestly, the next week and a half is a bit of a write-off. There’s a long, flat spell with hardly any energy in the water, so don’t bother clearing your schedule just yet. The only real window that gets me talking is further out, around the 17th and 18th of August.
The standout of the entire forecast is Monday the 17th of August at Jacks Point. That morning we’re looking at a clean, glassy start with a 4 ft swell rolling in from the SE. The period is a nice long 12 seconds, which means proper groundswell with some punch. The combined energy is a solid 364 — that’s a moderate, healthy pulse. Winds are glassy with a slight offshore touch from the west. It’s an advanced reef break, so it’s for the crew who know the lineup, and with a swell direction matching the optimum ENE, it should line up nicely. Crowds are sometimes an issue here, but on a Monday morning you might get a few sets to yourself.
Tuesday morning the 18th is also worth waking up for. Similar setup: 3 ft SE swell, 12-second period, clean northwest cross-off breeze, with combined energy at 310. Not quite the peak of Monday, but still very, very good for this stretch. The afternoons get a bit cross-on, so mornings are the call.
Before that, there’s almost nothing. A tiny blip on Sunday the 9th morning shows a 4 ft swell, but it’s a short 5-second period windswell — weak and choppy, not worth paddling out for. The rest of the first week is flat or blown out.
The water temp sits around 49°F with a positive anomaly of 2°F, so it’s running slightly warmer than average for August — not a huge surprise, but comfortable enough in a good wetsuit.
For the long range, keep an eye on the 17th and 18th. That’s your window. Until then, wax down the longboard for a flatwater paddle if you’re feeling keen.
Stay frothy.
Rusty.

Information about the Jacks Point Surf forecast
The above surf forecast table for Jacks Point provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jacks Point can be found by selecting the local surf guide option on the grey menu. Our Jacks Point 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 (Jacks Point) 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 Jacks Point 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.
Jacks Point is 4 km (2 miles) from the city of Timaru. If you plan a holiday in Canterbury, look for hotels and other accommodation in Timaru. Timaru has rooms for a wide range of budgets as well as car hire and transport links.
