The Lowdown
Alright, I’ll walk you through this outlook. The first few days aren’t much to write home about. On Tuesday, July 14, there’s a small 0.8m SSW swell, but it’s cross-off at 20 km/h and the combined energy is moderate (422). Just marginal.
The good stuff arrives Wednesday, July 15. Wednesday morning you’ve got a clean 0.8m west swell with a long 15-second period and light offshore wind from the ESE at 10 km/h. That’s prime – glassy, lined up. Combined energy is moderate (455). Afternoon is similar, with rain showers but still 0.8m at 15 seconds. This is your best call for the first week.
Thursday, July 16, steps down. Morning is 0.7m, 14 seconds, cross-off, energy at 203. Afternoon builds energy to 575 with a 0.7m SSW 17-second groundswell, but the wind hits 25 km/h cross-off. Marginal.
From Friday, July 17, through Sunday, July 19, it’s a bust. Strong 30 km/h cross-off winds, poor surf. Swell drops to 0.4m on Sunday with a 19-second period from the S – only good if you’re on a point or reef.
Monday, July 20, offers a 0.9m S swell at 16 seconds, but winds are 20-25 km/h cross-off. Marginal.
The real standout is Wednesday, July 22. Swell is only 0.5m, but the period is huge at 24 seconds – very long groundswell from the S. Combined energy is 683, punchy for the size. But winds are 25-30 km/h cross-off. This one’s for experienced surfers only – that long period will wrap into Tunnels but it’s tricky.
Thursday, July 23, and Friday, July 24, hold 0.7-0.8m with 18-20 second periods and moderate energy (674-708). Still cross-off, still marginal.
Then from July 25 to July 29, it’s a long run of poor surf. Winds stay strong out of the ENE/NE, 25-35 km/h, swell never tops 0.9m. Energy drops to 166 by the 29th. Not worth it.
Water temp is 80°F, normal for this time of year.
The only clear, clean window with decent waves is Wednesday, July 15. If you can get out then, you’ll find some smooth, lined-up rides. The rest is a cross-off wind slog.

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