The Lowdown

Alright, I’m looking at the forecast for Udo Shrine here. It’s a reef break, and it’s inconsistent, so we’ve got to be patient.

The next 16 days are a real mixed bag. For the first week, we’re looking at tiny, weak surf. The energy is low, and honestly, there’s not much to get excited about until we hit early August. The water temperature is sitting at 84°, which is about 1° warmer than normal for this time of year, so it’s a touch warm but nothing crazy.

Let’s start with the immediate future. Monday the 27th of July morning is glassy with a 2ft swell from the SE, period 10 seconds, and the combined energy is only 157 (moderate). It’s surfable, but very ordinary. The wind is light and glassy, so it’s clean, but there’s just no push. Afternoon goes cross-off and gets a bit messy.

Tuesday the 28th of July morning has clean offshore wind from the SW at 6 mph, with a 2ft SE swell. The energy drops to 98 (weak). It’s small and clean, but not doing much. The afternoon gets a bit more size at 3ft from the SSW but with a strong cross-off wind at 12 mph, which is not great.

Wednesday the 29th of July morning is glassy again, with a 2ft ESE swell, energy at 68 (weak). It’s clean but tiny. The rest of the week through to the 1st of August is a write-off: tiny waves, poor conditions, and very low energy, often below 70 (weak). There’s a gap of several days here with no real recommendations.

The first real standout appears on Monday the 3rd of August. The swell jumps to 4ft from the ESE with a period of 14 seconds, and the energy climbs to 638 (strong). The wind is cross-on from the NNE at 12 mph, so it’s a bit choppy, but that’s a long-period groundswell pushing in. The afternoon sees 5ft from the ESE, period 16 seconds, energy 975 (strong). The wind is still cross-on, but the raw energy is building. This is a reef break, and that long period (16 seconds) will wrap in nicely, but the onshore wind will mess with the surface. For a surfer who doesn’t mind a bit of texture, this is the start of the real action.

The absolute best of the outlook is Wednesday the 5th of August. The morning is glassy, with a 10ft swell from the east, period 17 seconds, and the combined energy is a massive 5491 (very strong). The wind is light SSW at 3 mph, and it’s glassy. This is a big, powerful groundswell with a very long period. For a reef setup like Udo Shrine, this will be firing. The afternoon is also a standout with offshore cross-off wind at 6 mph, and the energy jumps to 5786 (very strong). This is the peak of the window. The only catch is that 10ft is big—strictly for experienced surfers. The long period (17 seconds) means the waves will have serious power and long lulls between sets, making it easier to get out the back, but the take-off will be critical. If you’re not an expert, stay on the beach.

Thursday the 6th of August still has 10ft from the east, but the wind turns cross-on from the NNE at 9 to 12 mph, making it choppy. The energy is still huge (4911 to 5992), but the quality drops. Friday the 7th of August is similar, with 12ft from the east, but the wind is onshore or cross-on, so it’s messy.

The surf then drops off a cliff on the 8th of August, with a tiny 2ft NNE windswell, period 6 seconds, energy 28 (weak). It’s poor.

There’s a secondary pulse on Sunday the 9th of August with 4ft from the east, period 13 seconds, energy 398 (moderate). The wind is cross-on, so it’s not clean, but it’s a little something. That continues into the 10th and 11th, with the 11th of August seeing 6ft from the east, period 14 seconds, energy 1394 (strong), but the wind is cross-on or cross-shore, so it’s not perfect.

If you’re looking for the best window, it’s Wednesday the 5th of August. That’s the one. The combination of size, long period, and glassy to offshore wind is a true standout for experts. The rest of the window is either too small or too windy. Keep an eye on the 3rd and 4th for a building swell, but the 5th is the day.

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.
