The Lowdown

Alright folks, Rusty here with a look at what we've got coming down the pike at Navarro Rivermouth. Let's get into it.

Right off the bat, I gotta be straight with you – the water is chilly. We're talking 54°F and that's a full 4°F colder than usual for this time of year. You'll want a good hood and some booties for sure.

Now, for the surf. Look, this is a tough stretch. The forecast is pretty bleak for the next week and a half. The wind is almost always coming from the NW or W, giving us a persistent cross-onshore breeze that's just messing up the surface. It's frustrating because there's some swell energy in the water, but it's all getting chopped up.

Friday the 14th kicks things off with some weak, short-period NW swell around 4ft, wind is on it from the W at 6 mph, and the energy is a low 143. It's just poor surf conditions. The pattern stays the same through Saturday and Sunday, with swell dropping to about 2ft to 3ft and energy dipping below 100. The wind is either onshore or cross-onshore, and the wave comment is consistently "poor surf conditions."

We get a bit of a bump in swell energy on Monday the 17th, picking up to 4ft and 4ft with energy in the 156 to 167 range, but the wind is still cross-onshore from the NW at 9 to 12 mph. The waves are choppy and messy. Tuesday the 18th sees the swell building to 6ft in the morning (energy 475), but it's still cross-onshore and choppy. The middle of the week, Wednesday the 19th, has the biggest raw swell of the period at 7ft in the morning, with a solid energy reading of 1121. But again, that NW cross-onshore wind at 9 mph is killing it. The period is only 8 seconds, so it's short-period, wind-affected stuff. Not the kind of swell that's going to offer any quality.

By Thursday the 20th, the swell drops back to 3ft, though the period stretches out to 12 seconds from the WNW. That's a longer period, but the wind is still up at 12 mph from the NW, giving us a choppy, moderate cross-onshore. We then have a long stretch of days from Friday the 21st all the way through the end of the month where the conditions are just a write-off.

There is a small glimmer on Sunday the 23rd. The morning shows a 6ft NW swell, period of 8 seconds, and the wind is finally onshore from the W at only 6 mph. The wave comment shifts to "marginal surf forecast." The afternoon is similar, with a 7ft swell and light cross-onshore. It's the only time in the entire 16-day window that we get any kind of "marginal" rating, but it's still not great. The rest of the period is a repeat of poor surf, cross-onshore winds, and choppy conditions.

For a spot that's known to be inconsistent, this is a particularly tough run. The swell direction is mostly from the NW, which is the optimum direction for the break, but the wind is just constantly working against it. With the persistent cross-onshore wind and the poor surf quality, the setup actually looks more interesting for kite surfing than paddle surfing for most of this period.

So, in short, there are no standout days here. The best you can hope for is a marginal session on the morning of the 23rd, but even that's a big maybe. Forecasts can change, but right now, it's a long wait.

Rusty.

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 Navarro Rivermouth 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.
