The Lowdown
Imperial Version
Alright folks, Rusty here. Gotta be straight with you – we’re looking at a real frustrating run for 15th Street. The whole first week is mostly cross-on breezes and knee-to-waist high slop. It’s not going to be anything to write home about, and the charts are calling it "marginal" right through.
We start off on Friday the 24th of July with a weak 2ft swell out of the SW, but that wind is cross-on from the SW at 9 mph, so it’s gonna be choppy. The water is way warmer than normal, about 4° warmer than usual. The energy is moderate at 968, but the period is a massive 24 seconds – that’s a very long groundswell. At a beach and reef setup, that long period can make it break a bit too straight, making it tricky.
The wind stays cross-on all through the weekend and into the next week, with the swell slowly building from 3ft on Saturday the 25th up to about 4ft by Monday the 27th. The period is still super long, between 18 and 21 seconds. The energy climbs into the four-digit range (1169 on Monday morning), but the cross-shore wind is the spoiler. It’ll be bumpy, not clean.
The pattern keeps going like that – a bit of size but always a cross-on breeze. By Thursday the 30th, we get to 5ft from the S with a period of 15 seconds. From Thursday night into Friday the 31st, the swell jumps to a solid 7ft from the S, with the wind shifting directly onshore from the W at 9 mph. That’s moving into strong wave energy (1766) but with those big sets and onshore wind, it’s a frothy, blown-out mess. For beginners, 7ft is getting too big, and for everyone else, the 14-second period still means it might be shifty.
The best that’s on offer in this stretch is actually Saturday the 1st of August. The swell settles to a manageable 6ft to 6ft from the SSW, with a period of 13 seconds. The wind goes light and onshore from the W at 6 mph. That’s still offshore for 15th Street, which is the interplay of the wind being at your back. The ratings are only a 3/10, but compared to the rest, it’s the best window. The energy is still moderate at 1214. It’s not going to be perfect, but it might be the only window with a little bit of shape and some cleaner faces if you can get the tide right.
Then it’s all over. From Sunday the 2nd of August through to the end of the forecast on the 8th of August, the swell drops right off. We’re talking 1ft to 2ft with period dropping to 9 to 12 seconds. The energy drops to two-digit numbers (64-231). The winds are a mix, but the wave comment says it all: "poor surf conditions." There are no standouts. It’s a blank run of almost a full week.
If you’re desperate, Saturday the 1st is your only real shot. Otherwise, look elsewhere or take a rest. The water's warm, but the ocean’s not cooperating.
Rusty.

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.
15th Street is 5 km (3 miles) from the city of Encinitas. If you plan a vacation in San Diego County, look for hotels and other accommodation in Encinitas. Encinitas has rooms for a wide range of budgets as well as car hire and transport links.
