The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the cards for the coming weeks.

Well, honestly, it’s a pretty slow start out there. We’re looking at a real quiet patch to kick things off. The first few days are going to be a struggle, with tiny, weak swell and average winds making it hardly worth paddling out. The best you can hope for is a few knee-high wobblers, but honestly, it’s not much to write home about. We’re looking at a gap of a few days with no real recommendations.

Things start to get a little more interesting on Sunday the 19th of July. The morning will be clean under a northerly cross-off, but the swell is still pretty weak at 3 ft from the SSW. The real highlight of the day is the afternoon session. The wind drops right out, going glassy, and the swell kicks up a notch to 3 ft from the south. The energy is moderate (105), and it’s the cleanest the waves will be for a while. It’s small, but if you’re desperate for a slide, that’s your window.

For a bit of size, you’ve got to wait until Tuesday the 21st of July. The morning kicks off with a solid 7 ft SSW swell (678 energy), but it’s a little unruly and the wind is a moderate cross-off. It’s a bit of a beast, and over 5 ft, so it’s not for the beginners. The afternoon cleans up nicely with a 6 ft S swell and a gentle breeze, making for a much better prospect. This is the best looking swell window, but it’s a bit of a mixed bag with the wind.

Looking further ahead to the end of the month, the standout is shaping up for Monday the 28th of July. The morning session at Flies looks like the pick of the fortnight. We’ve got a clean 6 ft south swell (386 energy) with a light cross-off breeze. The period is 8 seconds, so it’s a decent groundswell that should offer some push. Over 5 ft, it’s intermediate to expert territory, but the conditions should be clean. The crowds are a *sometimes* problem here, and with surf like that, you can bet there will be a few out.

Tuesday the 30th of July is also worth a mention for the morning, with a 6 ft south swell (411 energy) and a light wind, but it’s a cross-on, so it won’t be as clean as the 28th.

The water temperature doesn't throw up any major surprises; it's about what you'd expect for this time of year.

So, for me, the best on offer is Sunday afternoon the 19th for the glassy, clean conditions, and Monday morning the 28th for the best combination of size, swell, and wind. The long-range stuff is promising, but as always, keep an eye on it.

Rusty.

Information about the Flies Surf forecast

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