Table - best surf conditions forecast for Coastguard Beach over the next 16 days.
Alright folks, Rusty here. Let’s be straight with you – this 16-day window for Coastguard Beach is looking like a real bummer. There’s nothing on the cards that’s worth paddling out for. The whole stretch is a write-off for decent waves.
The first record kicks off Saturday, July 11th, but it’s a total dud. We’ve got a tiny 1-foot SSE swell with a weak 7-second period and a combined energy of just 20. That’s barely a ripple. The water temp is sitting at 66°, which is about average for the time of year, but you won’t care about that when you’re just floating around.
The whole first week is a mess. Sunday and Monday see the swell drop even further, into 0.3 to 0.7 feet, with weak energy readings (11, 10, 5). On Tuesday, we get a 0.3-foot swell with a 15-second period, which sounds fancy, but it’s so small it’s useless. The wind is mostly cross-off or clean, but with no wave to work with, it doesn’t matter. The forecast scores are all zero. It’s just a flat spell.
Into the second week, things get a little more interesting in terms of size, but the quality is still poor. On Monday, July 20th, we see a 4-foot ESE swell, but it’s a short-period, wind-affected 5-second wave with choppy, cross-onshore wind. The combined energy hits 100 – moderate energy – but the conditions are rubbish. It’s the same story on Tuesday and Wednesday with 2 to 3-foot swells, but the wind is still onshore or cross-off, leaving a messy surface.
The only real spike in size comes on Thursday, July 23rd afternoon, with a 3-foot S swell and an 8-second period, giving a combined energy of 120 (moderate). But again, the wind is a moderate cross-onshore, making it choppy. Not a single session in the whole 16 days gets a score above zero. There’s a brief uptick on Saturday, July 25th, with a 3-foot SSE swell and a 10-second period, pushing combined energy to 167 (moderate), but the wind is onshore and the surf is still rated as poor.
With no consistency, no quality, and the break being a beginner beach break, this setup is honestly more interesting for kite surfing than for paddle surfing. It’s a blank run, and for this area, that’s pretty normal. Keep an eye on the charts, but for now, give it a miss.
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.
