The Lowdown
Alright, let's get into it. This is Rusty, bringing you the local outlook for Porsmilin.
First up, the water temp is sitting right around 64°, which is bang on average for this time of year. Nothing out of the ordinary there.
Alright, let's be straight with you – the next week and a half is a bit of a write-off for decent waves. We've got a long gap of poor surf conditions and very ordinary conditions stretching from Sunday the 9th right through to the end of that week. There's just no energy to get excited about; the combined swell energy is mostly a weak two-digit number, often under 100, and the swell heights are small, generally under 3 ft. The wind is mostly cross-off, which is okay, but the waves just aren't there.
The first real glimmer of hope arrives on the morning of Saturday the 23rd. We see a pulse of 4 ft, but it's a short-period SW windswell at 6 seconds, and the combined energy is still a moderate 190. It's surfable, but nothing to write home about. The afternoon of the 23rd gets a bit more interesting with a bump to 6 ft from the WSW, and the energy jumps to 402, but it's still a short period swell and the conditions are described as marginal.
The standout window is Monday the 24th. This is the one you want to circle on the calendar. The morning of the 24th sees a solid 6 ft of swell from the WNW, with a period of 10 seconds. The combined energy is a strong 654, meaning there's plenty of power in the water. The wind is a light N at 3 mph, basically a slight air, which will keep the surface clean. This is the best we've got in the whole 16-day run. It's not a huge day, but given the long flat spell, it's a proper window of opportunity. The afternoon holds similar size at 6 ft, but the cross-off wind is a little stronger, so get on it early.
Crowds at Porsmilin can be a factor at times, especially when the waves finally show up, so expect a few others with the same idea on the 24th. The swell direction is from the WNW, which is a good match for this sandbar break.
For the rest of the second week, it looks like we drop back into a funky mix of small, weak swell and poor conditions. Nothing else stands out as a goer.
So, overall, it's a long wait for a very short window. The 24th is the day. Don't sleep on it.
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.
