The Lowdown
Alright folks, it’s Rusty here, looking at the next 16 days for our little patch of coast. I gotta be straight with you – it’s a grim stretch ahead. The wave energy is just nowhere to be found, and when it does show up, it’s got issues. We’re looking at a long, dry spell.
For the first week and a half, from Friday the 31st of July all the way through to the 9th of August, it’s going to be a struggle. The combined swell energy readings are mostly in the double digits, barely cracking 100 (87) on Friday morning, which is a clear sign of very weak, half-hearted energy. The swell is tiny, hovering around 1 ft to 3 ft, and the period is short, often around 8 seconds. That’s just windswell with no punch. The water temperature is currently 66°, sitting a touch warmer than normal for this time of year, but that’s about the only warmth you’ll feel.
The wind is actually alright for a lot of this period – we get some clean offshore breezes from the NNE and N, especially on Saturday morning the 1st of August and Friday the 7th of August. But it doesn’t matter because the swell is just too weak. It’s like having a perfectly waxed board and no waves to ride.
The only spot that even gets a sniff of a pulse is Porsmilin, a sandbar that’s fairly consistent but needs the right conditions. This break is fairly exposed to the SW, and the optimum swell direction is SW. We do get a little bump in combined energy on Tuesday the 4th of August, hitting 148 with a 4 ft swell from the WSW, but the period is a weak 8 seconds and the wind is onshore from the SSW, completely ruining any chance of a clean wave. The same goes for the Tuesday afternoon and the afternoon of the 8th of August, where the energy hits 122 but the swell is still short-period and messy.
The absolute best we can hope for, and I use that word loosely, is the morning of Sunday the 9th of August. We get a 3 ft swell from the WSW at 9 seconds, with a combined energy of 118 – that’s moderate energy. The wind is a light breeze from the E, which is cross-offshore. The forecast says “surfable waves but very ordinary conditions,” and honestly, that’s the highlight. It’s not going to be good, but it’s the only time in the whole 16 days that isn’t a complete write-off.
After that, from the 10th of August onward, it’s back to tiny, weak, and often choppy conditions. The wind swings onshore or cross-onshore, and the swell barely registers. The 15th of August is a mess with a strong breeze from the WNW creating lumpy cross-chop, and the swell is only 2 ft – that’s not even a knee-high wave worth paddling for.
Honestly, for the first 10 days, the setup looks more interesting for a kite than a surfboard. There’s enough wind, but the waves are too small and weak for a proper paddle session. This is a proper blank run for the area. Don’t hold your breath; forecasts can change, but right now, this is a time to wax the longboard, maybe fix a ding, and just watch the horizon.
Rusty.

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

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 Porsmilin 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.
