The Lowdown
Alright, Rusty here. Let's talk about what's in the water for the next couple of weeks.
The first week and a half is a total bust. We're looking at a long dry spell with tiny, weak surf. Don't plan your life around it. The only break in the area is Udo Shrine, a reef that doesn't break all that often. The first several days through the end of July are all under 2ft with wave energy in the weak range. You'll get a few glassy mornings, like the 27th and 28th of July, but the waves are just too small to ride.
Things start to pick up around Sunday, August 2nd. We get a south swell pushing in with waves around 3ft and moderate energy of 331. The morning is glassy, which is a big plus. It's a solid start to the week.
The one to circle on your calendar is Saturday, August 8th. That's when the real deal arrives. A powerful east groundswell hits with waves at 10ft and a very long period of 15 seconds. The wave energy is a monster 4855, which is strong to very strong. The morning is calling for glassy conditions with a light breeze out of the northeast. This is an expert-only day. The water temp is about normal for this time of year. This east swell, with that long period, will work great on the reef at Udo Shrine, giving you some clean, lined-up walls.
The days before the 8th have the size, but the wind is a mess, blowing cross-onshore and making it choppy. The 8th is the clear winner. The first week is a write-off, but that second week, especially Saturday the 8th, is where it's at.
Rusty.

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