The Lowdown

Alright, Rusty here. Let’s have a look at what’s on offer for Porsmilin over the next couple of weeks.

To be straight with you, this is a quiet spell. The first few days barely have a wave you’d paddle for. We’ve got a gap from now until about the 4th of August where the swell is tiny and the wind is messy. Don’t bother checking the water yet – it’s not worth the walk.

The water temperature is sitting at 66°, which is a touch warmer than normal for this time of year, so you won’t need a thick suit.

The first real chance of anything surfable comes early on Tuesday the 4th of August. The swell pushes up to 4ft from the WSW, but the period is a short 7 seconds and wind is onshore from the SSW at 12 mph. The combined energy hits 159 (moderate). It’s not clean, it’s a bit lumpy, and honestly, it’s more of a frustrating session than a fun one. By the afternoon, the wind picks up to 16 mph, and the swell drops a touch. Keep the board in the car.

Wednesday the 5th of August sees the biggest swell of the whole outlook – 5ft to 6ft from the W and WNW, with periods still only 7 to 8 seconds. The combined energy jumps to 245 and 339 (moderate to strong), but the wind is cross-shore at 12 mph, creating a nasty cross-chop. It’s not clean, it’s a messy power. This isn’t the day for a smooth ride; you’ll be fighting for it.

Thursday the 6th of August offers a cleaner option. The morning has 5ft from the WNW, period 8 seconds, and a nice cross-offshore breeze from the NW at 9 mph. The combined energy sits at 238 (moderate). The afternoon stays clean but the wind picks up to 16 mph, and the swell drops to 4ft. It’s the best-looking morning in the first week, but still only marginal.

After that, the swell drops away again. The 7th, 8th, and 9th of August are tiny, with waves under 2ft and not worth the wax. The 10th of August has a brief lift to 4ft from the WNW with a clean cross-off breeze from the N at 6 mph, but the period is only 7 seconds – enough for a cruisy log session, but not exciting.

Later in the second week, the 12th and 13th of August show a small pulse of 3ft to 3ft from the W, with periods of 9 to 10 seconds and light cross-offshore winds. The combined energy is around 148 to 191 (moderate). It’s surfable, but ordinary. The 16th of August has a little bump of 3ft to 4ft from the NW with short 6-second period and a moderate offshore wind – again, nothing special.

If I had to pick a standout, it’s Thursday the 6th of August, morning session. The 5ft swell from the WNW with a clean cross-off breeze gives you the best chance of a decent wave. But keep your expectations in check – it’s not pumping, just the least bad of a quiet run.

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. If you surf the same spot (Porsmilin) 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 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.
