Table - best surf conditions forecast for Udo Shrine over the next 16 days.
The Lowdown
Alright, let's talk about Udo Shrine. This reef is exposed to the south and it's an inconsistent wave – doesn't break often, so when it does you've got to pay attention. Crowds are likely here, so be ready to share the peak. Water temp is sitting at 84.2°F which is about average for this time of year, nothing out of the ordinary.
The first few days are a bit of a write-off – tiny swell, mostly under 2 feet, and the wind is either cross-off or cross. Monday 27th and Tuesday 28th have poor surf conditions, not worth paddling out. Wednesday 29th morning shows a glimpse of hope with a glassy 1.6 ft from the ESE, but it's still very ordinary. Thursday through Saturday (30th July to 1st August) are flat and weak – combined energy barely hitting 50 (54 at best). The swell is just too small and the period short, around 9-10 seconds. You'd be better off waiting.
Sunday 2nd August brings a bit of a pulse: 1.3 ft but with a 17-second period in the afternoon, giving a moderate energy of 192 – still poor surf conditions though. Then Monday 3rd August morning sees a jump to 4.6 ft ESE swell with a 15-second period, but the wind is onshore and the conditions are marginal. The energy is moderate (783). That trend continues into Tuesday and Wednesday (4th and 5th) with swell building to 7.5 ft then 9.8 ft, but the wind is cross-on or onshore, making it choppy and messy. The energy climbs into the thousands (2,853 to 6,155), but the quality is lacking – the wave comment says "marginal surf forecast or questionable tide conditions." This is not the time to get excited.
Now, from Thursday 6th August onward, the swell really cranks – 13.1 ft on Thursday morning, 19.7 ft on Friday 7th, all the way up to 47.

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.
