Alright, Rusty here. Let’s look at what we’ve got.

Honestly, for the next 16 days at Navarro Rivermouth, it’s a tough stretch. The surf is there, but the conditions are just not cooperating. The whole pattern is dominated by a persistent cross-onshore wind that is wrecking the surface quality. There’s no standout day; everything is described as poor.

The water temperature is sitting at 52°F, which is a bit colder than what you’d usually expect for this time of year, so bring your thickest wetsuit.

We start off Sunday the 5th of July with a 5ft swell from the NW, period 8 seconds, but a cross-onshore wind from the SW at 9 mph has it choppy. The combined energy is moderate at 444. It’s a no-go. Monday the 6th and Tuesday the 7th are basically the same story: 5ft to 6ft of NW swell, but that wind just won’t let up, leaving the surface messy. Energy stays moderate, bouncing between 311 and 480.

By Wednesday the 8th, the swell is picking up to 7ft, and by the afternoon it’s 10ft. That’s expert territory, but with a 12 mph cross-onshore and combined energy jumping to 979, it’s just a bumpy, blown-out mess. Thursday the 9th is the biggest, with a 10ft NW swell in the afternoon and the combined energy hitting 1136 – that’s strong energy – but the 16 mph cross-onshore makes it a kite-surfing setup, not a paddle-surfing one.

The period drops to 7 seconds on Saturday the 11th and the swell backs off to 5ft. Short period and cross-onshore is a recipe for junk. The energy slumps to 261-286.

There is a slight glimmer on Sunday the 12th with a longer 10-second period on a small 3ft to 3ft NW swell, and the wind lightens to 6 mph from the SW then WNW. Still cross-onshore, so it’s not clean, but the energy is low (203-260) and it’s the closest we’ll get to a session. The 10-second period gives it a bit more shape, but the size is tiny.

From there, it’s more of the same through the second week. Tuesday the 14th afternoon brings a 8ft NW swell with 885 combined energy, but the cross-onshore ruins it. The real oddball is Thursday the 16th morning: a tiny 3ft swell but with a massive 19-second period from the WNW. That’s a very long-period groundswell, but at that size with cross-onshore wind, it’s not doing anything for the rivermouth. The combined energy is still a strong 1144, though.

By Friday the 17th and Saturday the 18th, the swell is over 7ft with combined energy rocketing up to 1789 and 1676 – very strong energy – but the wind is still cross-onshore and the surf is marginal at best.

In short, there are zero good surf days in this window. The consistent cross-onshore wind kills every swell. If you absolutely have to get wet, the morning of Sunday the 12th is the most rideable, but keep your expectations real low. Otherwise, leave the boards in the car.

Information about the Navarro Rivermouth Surf forecast

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