The Lowdown

Alright, let’s break down 15th Street in feet and Fahrenheit. The water’s sitting at 76°, which is way warmer than usual for this time of year, so you’ll be comfortable in shorts.

From Sunday the 2nd of August through the 9th, it’s a total write-off. Swell is tiny – 2ft to 2ft from the SW – and the wind is onshore or cross-onshore, making it a choppy mess. The combined energy is weak, staying under 200 (197), and everything is rated as poor. Even on the 7th and 8th when the period jumps to 19 seconds and energy hits 484, the waves are still only 2ft to 3ft with cross-onshore wind, so it’s not clean.

The 10th through the 13th are the same story: small SW groundswell, cross-onshore winds, and poor conditions. The energy is moderate, in the 300s to 400s, but the wave heights never get above 3ft, and the wind kills it.

The best window is the 14th and 15th of August. On Friday the 14th, the morning brings 3ft waves from the SW, building to 4ft in the afternoon from the SSW, with a long period of 18 seconds and 17 seconds. The combined energy hits 889 in the afternoon, which is strong. The wind is light and onshore, so it’ll be glassy. The morning of Saturday the 15th sees 4ft from the SW, with a 16-second period and energy at 722, again with light onshore wind. It’s a consistent beach and reef break, and the optimum swell is from the WSW, so the SSW is a bit off, but it’s close. The scores are marginal, but it’s the best you’ll get. Remember, this is over a week out, so it’s hopeful but not certain.

After that, the 16th and 17th drop to 3ft with similar energy, but the wind turns cross-onshore on the 17th, so it fades out.

The only time to really consider is the 14th and 15th. The 4ft waves on the 14th afternoon might be a bit much for beginners, and the long period means the waves will have some power, but at a beach and reef break, it could be a bit close-out prone. It’s a spot that’s often crowded, so you’ll have company.

Information about the 15th Street Surf forecast

The above surf forecast table for 15th Street provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 15th Street can be found by selecting the local surf guide option on the grey menu. Our 15th Street 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 (15th Street) 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 15th Street 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.
