The Lowdown
Alright, Rusty here again, same rundown in feet and miles. Coastguard Beach is a beginner-friendly break, fully exposed to the swell. Through this 16-day stretch, it’s mostly a quiet period. Water temp is about what you’d expect for the season, nothing out of the ordinary.
First few days, Thursday the 30th and Friday the 31st of July, are a write-off. Swell around 3ft, weak energy around 140, but onshore and cross-winds mess it up. Not worth paddling out.
Then a flat run sets in from August 1st through the 8th. Heights barely hit 1ft, combined energy drops to single digits or low double digits — 13, 8, that weak. Winds clean up at times, especially Friday afternoon (31st) with glassy conditions, but there’s simply no swell. It’s a dead spell.
The first real sign of life comes on Sunday, August 9th, about a week and a half out. A 2ft SE swell with a long 12-second period, combined energy hitting 146 (moderate). Morning wind is offshore from the west at 6 mph, near glassy — that’s a big positive for clean surf. But the window is narrow; by afternoon the wind turns onshore from the ENE at 9 mph, messing it up.
Surfable but only just. For beginners, it’s the cleanest small wave of the whole outlook, but don’t expect much power.
Monday the 10th and Tuesday the 11th bring onshore and cross-onshore winds, chopping up swell that runs 2ft to 4ft. Tuesday afternoon sees the highest energy of the whole period — 675 (strong) — but the wind stays messy from the ESE at 9 mph, making it lumpy.
Wednesday the 12th and Thursday the 13th keep the swell around 3ft with a long period, but cross-onshore wind keeps it from cleaning up.
By Friday the 14th, it’s fading, energy back to 96.
The one to aim for: Sunday morning, August 9th. Small but clean, offshore wind, and glassy conditions. Best chance for a smooth, easy paddle. Get there early.
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.
