The Lowdown
Alright, Rusty here again, but this time in feet and miles.
Let’s talk about 15th Street. The next couple of weeks are looking like a bit of a slog. The water is way warmer than usual for this time of year, about 74°F, which is a big anomaly—more than 5°F above normal. Feels like a hot tub.
We start off on Saturday, July 25th, with a weak pulse. A 3ft SW swell at a long 21 seconds, but the wind is cross-on. The energy is moderate (717). Not worth getting wet.
Sunday the 26th is similar. The swell bumps to 4ft from the SW, still long period around 19 seconds, but still cross-on. Energy is moderate (962). Sunday afternoon has a little lighter wind, but it’s not clean.
Monday the 27th through Tuesday the 28th offer a bit more size—up to 4ft to 5ft from the SSW—but the wind stays cross-on from the SW. The energy climbs into the strong range (over 1100), but it’s choppy and messy.
Wednesday the 29th holds at 4ft to 4ft SSW swell, still cross-on. Energy is strong (over 1100), but quality is poor.
Thursday the 30th of July, things get a little more interesting. The swell jumps to 6ft from the S, period drops to 14 seconds, and the wind turns onshore from the WSW. The energy is strong (1299). It’s a bit lumpy, but it’s the first real size.
Friday the 31st of July is the standout. Swell peaks at 6ft from the S, period still 14 seconds, with light onshore wind from the W to WNW. The energy is very strong (1350). This is the biggest swell of the window. It’s not perfect, but for experienced surfers, this is the best chance. The wind is light, making it rideable.
After that, it fades quickly. Saturday the 1st of August drops to 5ft and then 4ft, with light onshore wind. Energy drops back to moderate.
From Sunday the 2nd of August onward, it’s a bust. Swell drops below 2ft, energy falls into the weak range (below 300), and the wind stays cross-on or onshore. The wave comment is “poor” from the 2nd right through to the 9th. A long gap of over a week with nothing.
So, your best bet is the 31st of July. That 6ft S swell with light wind is the only real highlight.
Rusty, out.

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.
