Alright folks, Rusty here. Let’s have a look at what Big Rock has got cooking for us over the next couple of weeks.

Right off the bat, I gotta be straight with you – this is a tough stretch. We’re looking at a long, dry spell with barely a ripple worth getting wet for. The first real chance of anything rideable won’t show up until Tuesday morning the 14th of July, and even then it’s only a marginal call. Before that, from now through the weekend and into the start of next week, it’s mostly poor conditions with onshore wind. The swell energy is sitting in the low hundreds (between 246 and 872) most of that time, which is weak to moderate at best. You’d be fighting an onshore breeze for tiny, short-period leftovers.

Now, if you’re desperate for a paddle, Tuesday the 14th morning offers a glimmer. We’ve got a 2ft swell from the SSW with a period of 12 seconds and clean, offshore wind from the W at just 3 mph. The water temp is about average for this time of year, so no nasty surprises there. But the combined energy is only 275, so it’s weak. The conditions will be clean, but don’t expect much push.

The next little window that’s worth a look is Wednesday morning the 15th. A 2ft SSW groundswell with a long 17-second period, combined with offshore WSW wind at 9 mph. The energy is still weak at 274, but the long period means the few waves that do come through will have a bit of shape. Again, it’s marginal.

After that, things get messy again with cross-onshore winds and drop in size until we hit the 20th of July. Monday the 20th morning brings our biggest swell of the period: a 4ft S swell with a 14-second period. The combined energy jumps up to 840 (moderate). The wind is light from the SSW at 6 mph, which is cross-shore – not glassy, but manageable. This is the standout of the whole forecast, but it’s still labeled as marginal, so it’s a bit of a gamble. The swell direction from the S isn’t its absolute optimum (which is W), but it’s the best size we’ve got.

Tuesday the 21st morning pushes the size up to 5ft from the SSW, with energy hitting 1044 (moderate), but the wind swings cross-onshore and it gets a bit choppy. This is getting into the range where it might be too much for beginners, but for experienced surfers, it could offer some fun if the tide lines up.

Overall, there’s no real classic day in this window. The best bet for a surf is Monday the 20th morning at Big Rock. It’s the biggest and has the most energy, with light cross-shore wind. The rest of the time, you’re either fighting onshore breezes or dealing with tiny, weak swell. Keep your hopes low and your expectations realistic.

Rusty.

Information about the Big Rock Surf forecast

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

Big Rock is 11 km (7 miles) from San Diego. If you plan a vacation in San Diego County, look for hotels and other accommodation in San Diego. San Diego has rooms for a wide range of budgets as well as car hire and transport links.
