Table - best surf conditions forecast for Katagai over the next 16 days.
Alright, Rusty here, looking at the local surf for the next couple of weeks.
To be straight up with you, it’s looking like a pretty lean stretch ahead. The forecast is a bit of a bummer, with most days showing poor surf conditions. We’ve got a big gap of nothing really worth paddling out for starting now and running all the way through until the 20th of July. There’s just no real quality to get excited about, and the wind is mostly onshore or cross-onshore, so it’s gonna be choppy and messy.
The first real glimmer we see is on Monday the 21st of July. Katagai (breakwater) might just be worth a look in the morning. We’ve got a south swell pushing in at 5 ft from the ESE, moving with a period of 11 seconds. The combined energy is moderate (497). The wind is light from the south, making it a cross-onshore breeze, but it’s light enough that it might just be clean enough for a few fun ones. The water temp is about average for this time of year. It’s not a standout, but it's the best on offer.
Honestly, the only other date that might have something is Monday the 27th of July. That morning sees a bump in energy from a long-period groundswell, 4 ft from the ESE at 16 seconds, with strong combined energy (1180). But the wind is a moderate cross-shore from the NE, which will likely put a chop on it. Given the breakwater setup, that long period might make it a bit too straight, and the conditions are still listed as poor. It’s a long way off, so keep an eye on it, but don’t book the day off work just yet.
Overall, it’s a quiet period. The break is very consistent, but the conditions just aren’t cooperating. It tends not to stay this poor for long, so things could change.
Rusty.

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