The Lowdown

Right then, let’s have a look at what’s on the cards for Porsmilin over the next couple of weeks.

Honestly, for most of the forecast period, it’s a bit of a tough watch. We’ve got a long stretch of pretty ordinary conditions, with a lot of onshore and cross-onshore winds and choppy, lumpy seas. The swell energy is weak for the most part, with values like 340 (moderate) and 144 (weak) – nothing to write home about. The water temp is sitting around 64°, which is bang on average for this time of year, so no surprises there.

The first real glimmer of hope comes right at the tail end of the window. On Thursday, September 3rd, we finally see a shift. The morning session looks promising with a clean, cross-off wind from the north at 6 mph, and a solid 8 ft swell rolling in from the southwest. The swell energy jumps to 577 (moderate), and the light breeze should keep the surface clean. This is the standout window. Thursday afternoon stays clean with a cross-off NW wind at 9 mph and a 8 ft SW swell (energy 1041 – strong), but that size is getting into expert-only territory, so be mindful.

The rest of the second week looks messy again, with more onshore winds and smaller, weaker swell. The September 3rd morning is the one to circle on your calendar. Porsmilin is a fairly consistent sandbar, and with the swell coming from the southwest – close to its optimum direction – and light offshore winds, it could offer some fun, clean waves. Just be aware that crowds are possible here.

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.
