The Lowdown
Alright, Rusty here. Let me break down what's happening at Tivives over the next couple of weeks.
First thing you'll notice: the water temp is sitting at 87° – that’s way warmer than it usually is this time of year, so it's like stepping into a warm bath.
The next few days are pretty flat and sketchy. Monday the 17th has a tiny bit of swell but the cross-on wind and a threat of storms mean you're better off waiting. It’s not until Wednesday the 19th that things get interesting – glassy conditions and a 3ft south swell with a clean look, even if the period is short.
If you're picking a day, aim for Friday the 21st. The morning is glassy with a 4ft south swell, a solid 11-second period, and the wind blowing offshore out of the WSW. The wave energy is moderate at 337, so it's not a monster, but the conditions are going to be clean and the waves should have some nice shape. Just keep in mind, Tivives is inconsistent, so you might sit and wait a bit between sets.
Saturday the 22nd morning is another good slot – glassy again with a 3ft south swell and a 10-second period. Another solid session if you miss Friday.
The week after that is pretty slow. From Monday the 24th right through to Thursday the 27th, we’re looking at tiny 1ft swell with long periods – 18 seconds in some cases. That long period would be amazing at a point break, but here it means you’ll be waiting a while for knee-high waves that barely stand up. There’s a short window on Thursday the 27th morning with glassy conditions, but it's still very weak.
Things look like they might fire up again near the end of the month. Saturday the 29th and Sunday the 30th both show 3ft SSW swells with moderate to strong energy (591 and 501). The mornings have good wind, glassy on Saturday and clean offshore on Sunday, with 16-18 second periods. That combination could produce some longer, more lined-up waves, but it's still an inconsistent spot. It’s a promising signal for the end of the run, but it’s far out – check back closer to the day.
Overall: Friday the 21st morning is the one to chase.
Rusty.

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