The Lowdown

Alright, Rusty here again, same spot, different numbers.

Right off the bat, it’s a long, slow start for Porsmilin. From Tuesday the 21st of July through the end of the month, the swell is tiny – mostly 0.7ft to 2ft from the WNW, with periods between 8 and 10 seconds. The combined swell energy is weak, with numbers like 43 (moderate energy) on that first Tuesday afternoon, then dropping into the teens and twenties. Winds are offshore or cross-offshore a lot, so the water looks clean, but there’s just no height to ride. The water temperature is 63°, which is about normal for this time of year.

We finally see a pulse on Sunday the 26th of July. The swell jumps to 5ft from the WNW, but the period is a short 7 seconds, and it’s a cross-shore wind with a cross-chop. The combined energy hits 287 (moderate wave energy). Not great. Sunday afternoon improves a little with cross-offshore winds and 5ft, still short period, and energy at 317 (moderate wave energy). It’s only marginal.

The real standout is Monday the 27th of July, morning session. Swell is 5ft from the NW, period at 9 seconds, and a gentle cross-offshore breeze from the NNW. Combined energy is 380 (moderate wave energy). That’s clean, solid, and the best we’ll see. The afternoon gets windier and drops off. For a sandbar, that 9-second period is good – keeps the waves fun. Expect crowds to be possible. If you’re an intermediate, that Monday morning is your call.

After that, it fades fast. Tuesday the 28th has 4ft from the NW, but it’s ordinary. Then it’s back to tiny, weak swell all the way through the first week of August. By the 4th and 5th of August, the wind turns onshore from the SW and WSW, with swell up to 4ft but period down to 7 seconds, and the energy is moderate (141 on the 5th morning). It’s choppy and messy – more of a kite session than a paddle session.

So, big gap until Sunday the 26th, and the only true standout is Monday morning the 27th of July. 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.
