The Lowdown

Righto, let me break this down in feet for you. Lookin' at the next 16 days for Coastguard Beach, and I gotta be honest—it’s a flat spell with almost nothing to get excited about. This is a real quiet stretch.

The only session that even comes close is Sunday afternoon, the 6th of September. You’ve got chest-high swell pushing in at around 5 feet from the NE, period 7 seconds, with a light cross-off breeze comin' from the NW. The ocean’s clean, the combined energy is moderate (329), but that short period means it’s a bit weak and won't hold its shape too well. The break works best with a SE swell, and this is comin' from the NE, so the direction's off. Still, it’s the best window for a beginner, and you might only share the water with a few folks—crowds are just possible.

After that, Monday the 7th morning goes glassy but offers a tiny 2-foot NE swell (period 9 seconds) with an offshore wind, though the energy is super weak (71), so you’re lookin' at knee-high slop. The rest of the first week and well into the second is pretty much dust—messy wind, onshore chop, and swell readings in the gutter.

Things do pump up around Friday the 18th of September. On Thursday the 17th afternoon, you get 5 feet from the east, period 6 seconds, combined energy 171, but the wind is cross-on, so it’s choppy and not clean. Friday the 18th jumps to about 7 feet in the morning and 6 feet in the afternoon, out of the east with combined energy pushin' strong (500+). But the wind is still cross-on, and it’s messy. The big one lands Saturday the 19th morning—8 feet from the east, period 10 seconds, and the combined energy is very strong (1376). That’s big, dangerous surf for experts only, and with a 30 km/h cross-on wind, it’s lumpy and rough. Not good for a paddle surfer—more of a kite-surfing day.

After that, a long gap with nothing worth mentionin'. The beach is consistent, so this kind of dead run isn’t forever, but right now the surf IQ is low. Water temp is about normal for early September. Keep an eye out—forecasts can flip.

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.
