Boiler Bay Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s on the table for Boiler Bay.

We’ve got some small, clean waves kicking off the outlook right on Monday morning, August 31st. It’s nothing to get overly excited about, just a tiny 2ft swell from the southwest, but with light west winds it’s glassy and cross. The combined energy is weak (281), so think of it as a quiet, peaceful paddle more than a proper session. The water temperature feels pretty normal for the time of year, nothing radical.

Monday afternoon actually turns a bit messy – the swell bumps up a fraction to 4ft but the wind swings northwest onshore and the energy jumps up a notch (494). Still, the conditions are chopped, so I’d leave it.

Now Tuesday morning, September 1st, is where we get our first real taste of something better. A solid 4ft swell out of the northwest, with a decent 9-second period, and the wind goes clean offshore from the south-southwest at 9 mph. That’s clean, lined-up surf at Boiler Bay. Combined energy is moderate (410). Tuesday afternoon keeps the same 4ft swell and offshore breeze, slightly stronger at 12 mph, still clean. This is a good, fun working day for confident surfers.

Wednesday the 2nd gets bigger but rougher. You’re looking at a 7ft swell on Wednesday morning, but it’s short period (7 seconds) and the wind is fresh offshore from the south at 22 mph. Combined energy ramps up to strong (724), but that short period makes it bouncy and hard to hold. Not beginner territory – only for the advanced crew, and with rain falling, it’s a tough call. Wednesday afternoon sees an even bigger 10ft swell from the south-southwest with a longer 9-second period and a massive combined energy of 1567 – very strong. This is powerful, raw surf, suited only for experts and possibly more interesting for kitesurfing than paddling, given the strong gusty conditions.

Thursday September 3rd is where I’d circle the date. We’ve got a solid 7ft to 8ft groundswell from the west-northwest with a 10-second period, clean cross-offshore winds, and combined energy in the 1200–1300 range (very strong). The swell direction matches the optimum southwest direction, and with clean conditions, this is excellent for experienced surfers. Friday morning September 4th is almost as good: a waist-to-shoulder high 6ft swell from the west-northwest, glassy conditions (no wind), and combined energy of 949 – moderate to strong. That could be a standout session if you can get it. Friday afternoon gets a cross-onshore breeze, so morning is the window.

Saturday September 5th morning serves up another glassy session: 4ft, calm wind, combined energy at 541 (moderate). Lovely clean lines, but it’s only chest high.

After that, from Saturday afternoon right through to the end of the forecast, it’s a long stretch of poor or marginal conditions. The swell either drops to under 3ft or onshore winds dominate, and a lot of strong north-northwest winds with some solid 7ft close-out surf on September 12th. For most of the second week, the only real pulse is on Wednesday and Thursday September 9th and 10th, with 5ft–6ft swells from the northwest and west-northwest, but onshore winds ruin any chance of quality. Friday September 11th has a small clean-ish window in the morning (5ft, cross-onshore), but it’s nothing special.

Best on offer: Thursday September 3rd and Friday morning September 4th are the clear standouts – Thursday offers bigger, more powerful, clean lines for advanced surfers; Friday morning is glassy and smooth for those who want long, clean rides without crowd chaos (crowds are only sometimes an issue here). Don’t sleep on Thursday.

For the second week, the only glimmer is a possible early window on September 11th morning, but it’s a long shot. Better to nail the first few days.

Rusty.
