The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks.

It's a bit of a slow start, but we've got a window of rideable waves kicking off Tuesday morning. The overall pattern shows a moderate pulse of long-period groundswell straight away, but don't get too excited—the quality is a bit of a letdown. The water is a super unusual 4° warmer than normal for this time of year, which feels like bathwater.

The standout for the whole 16-day run is the early part of the window. Tuesday morning, July 28th, is your best bet. Oceanside Harbor will have a clean 4 ft SSW swell with a very long 17-second period, packing strong wave energy (1062). The wind is light and onshore from the SSW at 9 mph, which is a bit of a bummer, but it's light enough to keep things workable. That long period means the waves will have proper shape and power, but at a beach/jetty setup like this, those long gaps between sets can make it feel a bit stop-start. The afternoon cleans up a touch with the wind dropping to 6 mph, but the same solid energy is there. This is really the only window where the waves have any serious grunt, but the onshore wind holds it back from being epic; it's more of a "functional" surf than a glassy dream.

Wednesday through Friday sees the swell dropping. Wednesday morning is a bit choppy with a cross-onshore wind, and the swell dips to 4 ft. Thursday and Friday have similar 4 ft to 5 ft swell, but the wind stays cross-onshore, which will keep things bumpy. The energy is still moderate to strong (in the 600-800 range), but the texture is messy. This is still manageable for the advanced surfer that Oceanside Harbor is set up for, but beginners might want to sit this out—especially Friday morning when the swell hits 5 ft.

Then, from Saturday, August 1st, we hit a long, flat spell. The surf goes completely quiet, with swell dropping to 1 ft to 2 ft and poor conditions. This lull stretches all the way through to the end of the forecast on August 12th. There's a few tiny pulses of very long period swell (17-19 seconds) in the second week, but the heights are so small (1 ft to 3 ft) that even with clean onshore winds, there's just no energy to push a decent wave. The wave energy readings are all in the low hundreds, which is weak. Nothing to get excited about for the paddle surfer.

So, in short: jump on Tuesday and maybe Wednesday morning if you're keen. After that, it's a long, dry stretch of flatness. The waves might come back eventually, but not in this 16-day window.

Rusty.

Information about the Oceanside Harbor Surf forecast

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

Oceanside Harbor is 8 km (5 miles) from the city of Oceanside. If you plan a vacation in San Diego County, look for hotels and other accommodation in Oceanside. Oceanside has rooms for a wide range of budgets as well as car hire and transport links.
