The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.

We’re lookin’ at a solid run at Dumps, a sandbar set-up that’s inconsistent but when it turns on, it can be a real treat. The water temp’s about average for this time of year, so no shock to the system. The pattern starts with clean, fun waves and builds into some serious muscle, but you gotta pick your moments.

The action kicks off Saturday morning, August 1st. We’ve got a sweet 4ft SW groundswell (period 14 seconds) with glassy conditions and a light ENE breeze. The combined energy is moderate at 581. This is a real nice start – clean, punchy, and not too crowded. That afternoon the wind shifts to a light S cross-off, keepin’ it clean.

Sunday the 2nd is a bit of a mixed bag. The morning is a little bumpy with a cross-shore wind, but Sunday afternoon turns glassy again with a 4ft SW swell. That’s a good window for a late session.

Monday the 3rd is a standout. The morning is glassy with a 5ft SW swell (12-second period) and the energy has jumped to 858. The afternoon is even better with a 4ft WSW swell, cross-off wind, and a combined energy of 930. This is the best of the first week – clean, solid, and with that longer period, you’ll feel the power.

Tuesday the 4th starts glassy again with a 5ft SW swell, but the afternoon gets messy with a cross-onshore wind and poor conditions. Wednesday the 5th is a write-off for paddle surfing – strong 20-25 km/h cross-onshore winds, 8ft to 10ft of SW swell, and a combined energy over 3200. That’s kite-surfing territory, not for a stick.

Thursday the 6th and Friday the 7th see the swell jump to 12ft and 8ft respectively. The wind is favorable (cross-off or light onshore), but the size is too big for this break. It’s a no-go for paddle surfing. Saturday the 8th brings a 10ft WSW swell, but the morning is clean with a light cross-off and a massive combined energy of 5700. This is excellent for experienced surfers only. The afternoon gets a bit messy.

Sunday the 9th is a beast – 12ft SSW swell and 35-40 km/h winds. The energy is 5553, but it’s simply too big and blown out. Monday the 10th is a mess with near-gale winds. After that, we’ve got a few days of smaller, cleaner surf from Tuesday the 11th through Friday the 14th. The 13th of August Thursday afternoon is a real gem – glassy, 6ft WSW groundswell with a 16-second period, and a combined energy of 1564. That’s a long-period groundswell that’ll wrap in nicely at a sandbar, giving long, open walls. It’s a standout for the second week. The morning of the 14th is also good with a glassy 4ft swell.

The last few days into the 16th see a bit of onshore wind and a big 12ft swell on the 16th, which is just too much. So, the pick of the crop is Monday the 3rd for the first week, and Thursday the 13th afternoon for the second week. Crowds are possible at Dumps, but these windows are worth the gamble.

Rusty.

Information about the Dumps Surf forecast

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