The Lowdown

Alright, let's break down the coming waves. I've been staring at the charts for Coastguard Beach, and honestly, it's a bit of a quiet stretch ahead. We've got a full 16-day window starting now, but there aren't any standout sessions where everything clicks for a proper surf. The wind and swell just aren't lining up to give us any real juice.

Let's walk through it. Right from Tuesday the 1st, we're looking at tiny, weak surf. We're talking 0.3 ft to 2 ft with messy cross-onshore winds. It's a non-starter. Wednesday and Thursday are more of the same – small, weak, and choppy. The energy is just pathetic, with combined swell energy readings barely hitting double digits, mostly sitting between 13 and 87. That's weak, flat energy.

Friday the 4th and Saturday the 5th don't offer any hope either. The swell stays below 3 ft, and while we get a bit of clean wind on Saturday afternoon, it's still only 2 ft from the NNE. Not enough to get excited about. Sunday the 6th is a write-off with howling winds up to 28 mph.

Now, Monday the 7th is the most interesting day in the whole outlook. The swell bumps up to 4 ft from the NE, and the combined energy jumps to 149 – that's moderate energy, finally. It's still a beginner-friendly size, but those cross-onshore winds at 15-16 mph are going to chop it up. It's not clean, but it's the biggest push we'll see. For an experienced beginner, it's the pick of a rough bunch, but don't expect perfection.

After that, it's a long, drawn-out fade. From Tuesday the 8th all the way through to Wednesday the 16th, the swell drops back to 0.7 ft to 2 ft. Wind directions flip around from onshore to cross-offshore, giving us some clean conditions on a few days (like the 9th, 10th, and 11th), but with next to no swell. It's flat and clean, which is a cruel joke. The energy readings are in the single digits and low teens. You'd be better off on a paddleboard.

For the surf here at Coastguard Beach, it's mostly a consistent break, so it tends to have something, but this run is a real dud. Don't hold your breath.

This is a bust for the most part. Monday the 7th is the only day worth even looking at, and even then, manage your expectations. For the rest of it, the only thing consistent is the lack of surf.

Rusty.

Information about the Coastguard Beach Surf forecast

The above surf forecast table for Coastguard Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Coastguard Beach can be found by selecting the local surf guide option on the grey menu. Our Coastguard Beach 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 (Coastguard Beach) 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 Coastguard Beach 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.
