The Lowdown

Alright, let’s break down what’s comin’ our way.

Alright, listen up. We’ve got a bit of a slow start, but this window is gonna build into something pretty special. The first few days are a bit of a write-off, but don’t bail on the week just yet. The real action kicks off mid-week with a solid groundswell and some proper clean conditions.

The first real chance to get wet comes on Tuesday morning, July 21st. Dumps is waking up with a clean 8ft southwest swell. The wind is glassy – absolutely dead calm – and the water temperature is sitting at 59°F which is pretty normal for this time of year, nothing wild there. The wave energy is seriously pumping, with a combined energy of 2329. This is a long period groundswell at 14 seconds, so you’re gonna get proper shaped waves with long lulls between sets. That makes paddling out easier, but the sets will be packing a punch. This is one for the experienced crew – it’s too big for beginners and the power is real. This is a standout session.

The swell holds through Tuesday afternoon, still a solid 8ft, but the wind swings cross-shore and the conditions get a bit more mixed. It’s still good, but the morning is the pick.

Moving into the Thursday, July 24th window, we get a pulse of really big energy. Friday morning looks like the swell is hitting 12ft with a 14-second period. The combined energy is a massive 5363. That’s way too big for Dumps – the file says it’s predicted to be too big for this break. It’s an expert-only affair if you’re brave, but the wind is offshore and clean. Friday afternoon is a touch smaller at 10ft, with cross-offshore winds, and the energy is still huge at 4620. This is the second standout period for the strong, confident surfers.

Saturday, July 25th cleans up nicely. Morning and afternoon both see 7ft and 8ft southwest swell with cross-offshore winds and clean conditions. The energy is still strong (2792 and 1958), and it’s far more manageable for a strong intermediate. This is a solid day for anyone who knows their way around.

After that, the swell starts to taper and the wind gets a bit more messy through the end of July and into the start of August. Monday, July 27th morning offers a smaller 5ft southwest swell with clean conditions, which is a good option for a more relaxed session, but the energy is way down.

The last real spike to look out for is on Tuesday, August 4th. The swell jumps back up to 8ft and 8ft on Tuesday morning and afternoon, with a super long period of 16 seconds – that’s very long period groundswell. The combined energy is back up over 3000. But the wind is a fresh breeze from the southeast, which is cross-offshore, keeping it clean. It’s promising, but it’s a long way out, so keep an eye on it.

For the last few days of the forecast, the swell drops right off – 3ft and 3ft, and the energy is weak. It’s not worth paddling out for.

So, to sum it up: Tuesday morning, July 21st is the absolute standout for quality and clean conditions. Friday, July 24th is the big-wave standout for the experts. The rest of the week has plenty of good to excellent windows, but those two are the gems.

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.
