The Lowdown
Alright, let’s break down what’s on the table for the next couple of weeks. Honestly, looking at the whole picture, this is a pretty flat and ordinary run for the most part. There’s no real swell to speak of for the first few days, and the wind is mostly a problem. The one true standout window is a short, clean window early next week, but even that is just a brief moment of clarity. Let’s get into it.
We start off this Saturday afternoon, July 25th, with almost nothing. A tiny 0.3-foot south swell with a short period, paired with a moderate onshore breeze from the ESE. The water temp is sitting at 70°, which is a bit colder than normal for this time of year. That’s not a big shock, but it’s worth noting if you’re heading out. The combined energy is a measly 1 (one), so there’s not a wave to chase. Sunday and Monday are flat with poor conditions, and the wind is cross or onshore. It’s a rough start.
The first real glimmer of hope comes on Wednesday, July 29th. The swell starts to build but it’s messy. The morning is a 4-foot south swell with a moderate cross-onshore breeze from the east, and the energy climbs to 172 (moderate). It’s still not good. By Wednesday afternoon, we get a 5-foot south swell, but the wind shifts to a fresh 19 mph north cross-offshore, and the energy is 259 (moderate). The report says “clean” but the wind is strong. It’s a bit of a gamble.
Thursday, July 30th, is where things might get interesting. In the morning, we have a 4-foot south swell, period 9 seconds, with a moderate offshore wind from the NW. The energy is 181 (moderate). The conditions are described as “clean” and “surfable but very ordinary.” That’s the best we’ve seen. The afternoon is a bit smaller, 3 feet from the SSE, with a lighter cross-offshore wind. It’s not a classic, but it’s the first real opportunity.
Friday, July 31st, is a step back. The swell drops to 3 feet, and the wind is light and cross-offshore in the morning, but the energy is only 108 (moderate). The afternoon goes back to poor conditions.
Now, the standout. Saturday, August 1st, early morning. The wind is a light 3 mph from the SW (cross-off), the swell is 3 feet from the SSW with an 8-second period, and the combined energy hits 253 (moderate). The conditions are clean. This is the best on offer. It’s a small window, but it’s the only time the stars align. The offshore wind is light, and the swell is just enough to get into. The afternoon goes bad again, with a moderate cross-onshore wind.
Sunday, August 2nd, is a write-off with a choppy cross-onshore wind and a small, weak swell.
Monday, August 3rd, is the other real standout. The morning is clean, with a light 6 mph NNE cross-offshore wind, a 4-foot SSE swell, and a strong energy reading of 316 (moderate). The swell direction is coming from the SSE, which is in the ballpark of the optimum SW direction for this spot. The period is 8 seconds, so it’s a short-period swell, but with the light wind, it should be offering some fun, clean waves. The afternoon again goes to crap with a strong onshore wind. So the window is early Monday morning.
The rest of the second week is a mess. The wind is mostly onshore or cross-onshore, and the swell is small and weak. Wednesday, August 5th, offers a 4-foot south swell in the afternoon, but the wind is a moderate 12 mph onshore, making it choppy. Thursday, August 6th, is flat and weak. Friday, August 7th, is small and messy. Saturday, August 8th, is tiny.
Sunday, August 9th, ends the run with a 5-foot south swell in the afternoon, but the wind is a fresh 19 mph cross-offshore from the WSW. The energy is 143 (moderate), but the wind is strong. It’s clean but powerful and a bit of a handful.
So, the bottom line: If you have to pick a time, the absolute best is the early morning of Saturday, August 1st, and the early morning of Monday, August 3rd. The Monday morning has a bit more size and energy, with a light favorable wind. That’s your best bet. The rest of the time, you’re battling the wind or waiting for a wave.

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.
