Hey folks, Rusty here. Well, it's a bit of a slow start for the next few days, but don't write this week off just yet. We've got a bit of a wait on our hands, but some real gems are lining up, especially for the crew who can wait for a midweek session.

The first couple of days are pretty flat with nothing worth jumping in for. You're looking at a blank run from now until Monday the 6th of July. Then things start to wake up.

Monday the 6th of July sees the first real pulse of energy. Dumps is showing a clean 5ft swell from the SW with a solid 11-second period. The combined swell energy is moderate at 1302. Winds are light and offshore in the morning from the SE, so expect some clean lines. It's not a monster, but it's a start.

The standout period looks like Wednesday the 8th of July right through to Saturday the 11th. Tuesday the 7th of July morning at Dumps is special. The wind is dead calm, glassy as a lake, with a clean 6ft SW groundswell (12-second period). The energy is strong at 1242. That's the pick of the first half of the week. The water temp is about average for the time of year.

Wednesday the 8th of July morning gets even better. The swell jumps to a solid 8ft from the SW, period stretching out to 13 seconds. Combined energy is strong at 3412. And the wind? Glassy again from the WSW in the morning and cross-offshore in the arvo. This is for the experienced crew though—over 8ft is expert territory, and Dumps is an inconsistent sandbar that doesn't always fire, so when it does, you get on it. Crowds are possible here, so expect a few others with the same idea.

Thursday the 9th of July holds that 8ft SW groundswell with a 14-second period, and we get a gentle offshore breeze from the SE. Clean, powerful, and lined up. By Saturday the 11th of July, it's backed off a touch to 6ft from the SSW, but still with that long-period energy (13 seconds) and clean offshore wind.

Now, after that run, there's a bit of a lull again. Sunday the 12th of July has some size, 7ft, but the wind swings onshore and messy. Monday and Tuesday the 13th and 14th are blown out with strong cross-onshore winds. We're looking at poor conditions until Wednesday the 15th of July, but then it gets huge. We're talking 12ft to 15ft SW swell. That's too big for Dumps, and the forecast actually says it's too big for the break. That's big-wave territory only, and only if you've got the quiver and the nerve. The energy readings are off the charts—8767 on Wednesday afternoon—but honestly, for most of us, that's a day to watch from the beach.

Friday the 17th of July cleans up again, with a more manageable 10ft SSW groundswell and light offshore winds. By Saturday the 18th of July, it's dropping back to a clean 6ft with glassy conditions. That's a promising long-range call, but remember, it's a way off and forecasts can shuffle.

For my money, the best on offer is Wednesday the 8th of July and Thursday the 9th of July mornings at Dumps. Solid, powerful SW groundswell, glassy or offshore winds, and enough size to get your blood pumping. Get in the water, and be ready for a few mates in the lineup.

Stay stoked,
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.
