The Lowdown
Right, folks. Rusty here. Let’s have a look at what’s on the cards for San Mateo over the next couple of weeks.
First things first, there’s a dry spell coming. The forecast is pretty quiet for the opening days, with small, messy, and generally poor conditions filling the calendar from Saturday the 18th right through until the end of the week. The water is running much warmer than normal for this time of year, coming in at a balmy 80°F.
We’re looking at a bit of a wait, but the first real chance to get wet comes on Tuesday morning, the 21st of July. San Mateo should see a waist-high, 4ft swell from the SW, with a clean cross-offshore breeze. The combined energy is moderate (544). It’s a start, but nothing to get too worked about.
The real standout, the one you’ve been waiting for, is Monday morning, the 27th of July. This is the pick of the bunch. San Mateo will be cooking with a solid 5ft SW swell, groomed by a clean, cross-offshore breeze. The water will be smooth, the waves will be proper, and the combined energy hits a strong 1180. This is excellent surf for experienced surfers. It’s an inconsistent spot, so you’ll need to be patient between sets, but when they come, they’ll be worth it. You’ll want to be out there early, as the afternoon gets blown out.
Following that, Wednesday morning, the 29th of July, is another one to circle. The swell holds at 5ft from the SW, and the wind is glassy. That’s right, glassy. Zero wind. The combined energy is strong (1040), and the conditions are again excellent for the experienced crew. This is a long-period swell (15 seconds), so it’s going to offer some proper lines and make paddling out a bit easier between sets.
The rest of the run is a mixed bag of afternoon onshores and smaller, choppier conditions. Don’t hold your breath for the 30th onward, as the swell drops off and the wind becomes a problem again.
So, to sum it up: the first week is a write-off, but the 27th and 29th of July are the ones to hunt. Mark your calendar.
Rusty.

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