The Lowdown
Alright, Rusty here. Let’s get straight into it.
To be brutally honest, Harbor House is looking at a pretty flat and frustrating 16 days. The surf just isn’t showing up. We’re talking about a long, quiet stretch where you’d be better off leaving the board at home.
Looking at the first few days, from Sunday the 16th right through to the end of the month, there’s just nothing doing. The swell heights are tiny, mostly around 0.7 ft to 2 ft, with short, weak periods. The combined wave energy is pitiful – it’s barely cracking 20 on the best days, which is essentially no energy at all. There’s a tiny bump of energy on the 26th and 27th of August, with the combined number hitting 45 and 61, but the swell is straight onshore from the east, and the height is still only 1.0 ft to 1 ft. That’s not rideable surf, that’s just messy, choppy water. For a breakwater spot that’s already inconsistent, this is a total write-off.
Even the rare moments with glassy conditions, like the morning of Tuesday the 18th, are useless because there’s literally no swell to push through.
So, what’s the takeaway? There are no standouts. Not a single window where the wind, swell, and conditions line up. The water temp is about 87°F, which is a touch warmer than average for this time of year (anomaly of 2°F), but that’s small comfort when the ocean is flat.
This is one of those blank runs that’s more normal for this area. If you’re desperate, you’re looking at a kite, not a paddle. The onshore winds and tiny, bumpy swell on the 23rd and 24th might at least give a kite something to work with. But for a surf? Don’t bother.
Stay patient. Forecasts can change.

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