The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks. It’s a bit of a slow starter, but the back half of the forecast has some real potential.

We’re kickin’ off with a bit of a flat spell. The first few days are a write-off with tiny, weak swell and a combined energy that barely registers (17). The water’s sittin' at 63.1°, which is bang on average for this time of year, so at least a paddle won’t be a shock to the system.

Monday the 20th through Friday the 24th of July is pretty much a bust. We’re looking at waves barely 0.7 ft to 1.3 ft, and while the wind is often offshore or light, there’s just not enough juice to push a longboard around. You’d be better off takin’ a few days off.

Things start to shuffle awake on Saturday the 25th. The swell bumps up to 3.0 ft from the NW, but it’s a messy, short-period windswell (6 seconds) with a cross-shore breeze. The combined energy is still weak (83). It’s not great, but it’s a sign of life.

Now, here’s where it gets interesting. The real show starts to build on Sunday the 26th of July. The swell jumps up to 5.6 ft from the WNW with a period of 7 seconds, and the energy ramps up to moderate (314). Monday the 27th holds that size and actually cleans up a bit, but the forecast notes “marginal surf forecast or questionable tide conditions,” so don’t get your hopes up too high.

The standout window is Tuesday the 28th of July, and then again on Friday the 31st of July.

On Tuesday morning the 28th, we’ve got a solid 4.6 ft of WNW swell running with a 10-second period. The combined energy is pumping at 386 (moderate), the wind is a light N/NW breeze, and the break is well-exposed to that SW-optimum swell direction. This is the one to circle on the calendar. The water’s still a comfortable 63.1°, and while the crowds at Porsmilin can be a thing sometimes, for a morning like this, it’ll be worth it.

Then, on Friday the 31st of July, morning looks like another cracker. We’re seeing 4.9 ft of WNW swell with a 9-second period, energy at 368 (moderate), and a light N wind. That’s the kind of setup that can turn a sandbar into a fun little wave.

The rest of the first week of August trails off into smaller, ordinary surf with periods dropping back and cross-shore breezes taking over. Nothing to get too excited about.

So, in short: the first week is a flat, frustrating wait. The real deal is the last few days of July, with Tuesday the 28th and Friday the 31st lookin’ like the best shots. Get out there and enjoy it.

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.
