The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks. It's a bit of a mixed bag, but I'll cut through the noise.
First up, the main event on the cards is a pulse of solid energy that shows up on Saturday the 25th of July. It's not a perfect picture, but it's the only real window of size we've got. The morning starts tiny with a 0.7ft ESE swell, but the real action is the Saturday afternoon. That's when we see a 8ft ESE swell roll in, packing some serious grunt with a combined energy reading of 3238 (moderate wave energy). The bad news is the wind is cross-shore and the surf conditions are described as marginal, with a cross-chop making it a bit messy. The swell is big enough to get your heart pumping, but it's not going to be a clean, classic session. For a beginner, that 8ft is going to be a handful, but for the experienced crew, there's power to be had.
The water temp is about average for this time of year, so nothing unusual to report there.
After that Saturday afternoon spike, the outlook drops off a cliff. Sunday the 26th of July has a 13ft NW swell in the morning, but the wind is a screaming 59 mph storm force. That's not surf, that's a survival mission. The combined energy is 2302 (moderate wave energy), but the conditions are just horrendous. The rest of the week and into the following week are a write-off. We're looking at a long, dry spell from the 27th of July right through to at least the 9th of August. The swell is tiny, mostly under 2ft, and when there is a little pulse, the wind is onshore or cross-onshore, making it choppy and blown out. A few days in early August (the 5th and 6th) flirt with some clean offshore winds, but the swell is barely a ripple at 0.7ft to 2ft. It's frustrating, but that's the way it goes sometimes.
For a sheltered spot like Big Wave Bay, the optimum swell direction is NE, but the only sizeable swell we get is from the ESE. That mismatch, combined with the wind, means the setup is just not working for us. Between the storm-force winds and the blown-out conditions, this is looking more like a kite surfer's playground than a paddler's paradise for the foreseeable future.
Stay patient, lads. This blank run is a bit of a bummer, but forecasts can change. For now, the best, and really only, option is to try and get on that Saturday afternoon 8ft ESE swell, and just make the best of a messy situation.

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