The Lowdown
Alright, I’m gonna level with you. This forecast for Porsmilin is a real bummer. There isn’t one good surf option in the whole 16-day window. The wave energy is just too weak, and the swell is too small and sloppy to get the heart pumping. It’s one of those stretches where the ocean decides to take a nap.
Looking at the numbers, the combined energy of all swells directed here barely gets above 80 (83) on the afternoon of Thursday, July 30th, and that’s the peak. That’s weak sauce, barely enough to push a longboard around. The wave heights are tiny, mostly between 1.0 ft and 3 ft, with a short, messy period. The water is a touch warmer than normal for this time of year at 66°, but that’s small comfort.
The first few days are a total wash. Thursday afternoon the 30th is a cross-shore mess with a chop. Friday the 31st looks a bit cleaner with a cross-offshore wind from the NNW, but the swell is only 3 ft and 2 ft, and the call is “poor surf conditions.” Saturday, August 1st, has a tiny 2 ft leftover with a clean offshore wind, but it’s just not enough to do anything with. The whole first week is a struggle.
Then we hit a long, dry spell. From Sunday, August 2nd, right through the 12th of August, the swell is either non-existent or barely knee-high. The energy numbers are in the teens and thirties, which is just a ripple. The winds are often clean, but you can’t have a session on no waves. The 6th and 7th of August see some long-period groundswell (11 seconds and 10 seconds), but the height is a pathetic 1.0 ft. That’s the kind of energy that would be great for a long point break, but at that size, it’s just a slow, rolling bump.
The only tiny, tiny glimmer is on Monday, August 10th, in the morning. The wind is glassy – dead calm – and the swell is only 1 ft. It’s a truly flat day, but if you had a longboard and a lot of patience, you might snag a couple of wobbly ones. The energy is a sad 17.
The final few days, from the 13th of August onward, are more of the same: small, weak, and clean, but without any real push. The consistency is “fairly consistent” for Porsmilin, meaning it usually gets waves, but this forecast is just a dead run.
For a spot like this, a blank run this long is a bit unusual, but these forecasts can change. For now, I’d say leave the sticks at home and watch the wind. If the wind picks up, this setup looks more interesting for kite surfing than paddle surfing, given the onshore wind and tiny swell.

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.
