The Lowdown

Alright, let me have a look at what's on the table for the next couple of weeks. The main show is here at Udo Shrine, and it's a bit of a mixed bag. The water is sitting at a warm 86° right now, which is a touch warmer than normal for this time of year. The early days are tiny, but there's some serious size on the horizon, though we'll have to battle the wind to get it.

This first Saturday and Sunday morning are looking small but promising for a clean session. Saturday morning, the swell is a tiny 1 ft from the southeast, but it's dead glassy with no wind. It's small, but you can still have a laugh on a longboard. The combined energy is weak at (32), so don't expect much push. Sunday morning is the real standout of this first week, though. The swell jumps to 2 ft from the east-southeast with a long-period groundswell of 16 seconds, giving it moderate energy (256). The wind is light out of the east at 3 mph, making it glassy. This is the best call for a clean, fun session at Udo Shrine for the next few days.

Come Sunday afternoon, it's getting a touch more wind and some clouds, with the swell building to 3 ft and a 15-second period (355 energy). It's a bit dialed back by a cross-shore breeze, so not as clean as the morning.

Then things get wild. From Monday, the 5th of August, the swell really starts to pump, but it's not for the faint of heart. Monday morning we're looking at 5 ft from the ESE with a 16-second period, but it's blown out by a 12 mph cross-onshore (1339 energy). That's already too big for beginners. By Wednesday, the 7th of August, we're seeing 16 ft to 18 ft swells (a massive 14,158 to 19,248 energy), and the wind is howling at 22 mph cross-onshore. This is huge, powerful groundswell, but the conditions are lumpy and messy. While there's a note that the wind and tide are favorable for the swell size, the raw power is only for very experienced surfers, and even then, the onshore wind is going to chop it up. This continues into Thursday and Friday with massive 28 ft and 23 ft swells and gale-force winds. This is more of a reef-safety situation than a surf session.

By the second week, the energy drops but the wind stays nasty. From the 10th of August onwards, we're seeing persistent onshore and cross-onshore winds from the east and southeast, often at 25–40 mph, with storm risks. The swell drops from 8 ft down to 2 ft, but it's blown out and choppy. There's a marginal window on the morning of Wednesday, the 14th of August, with a 6 ft swell from the east (1,175 energy), but a moderate cross-shore chop will make it messy.

So overall, the pick of the period is that glassy Sunday morning, the 4th of August. For the rest, unless you're a pro looking for a beating in dangerous winds, it's not worth paddling out. If the wind keeps up like this, the setup might be more interesting for kite surfing than paddle surfing during the big swell days.

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.
