Harbor Entrance at Eureka Surf Forecast and Surf Report

Alright, let’s get stuck into it.

Honestly, for the next week and a bit, we’re looking at a pretty flat, frustrating stretch of surf here at Harbor Entrance at Eureka. The swell windows are there, but the wind and the energy just aren’t lining up to give us anything worth paddling out for. It’s going to be a waiting game, and more than a few sessions where you’re just sitting on the beach, watching the horizon.

The first real chance of anything comes this Thursday morning with a small 3ft southwest swell, but it’s carrying a long 17-second period. Now, that long period is prime for a point or reef, but for a beach/harbormouth like this, it might just be breaking too straight. Water temp is a pretty normal 57.7°, so nothing unusual there. But the conditions are marginal at best, with a light NNW breeze on it. The energy is weak at 720. Thursday arvo is much the same story, just a touch more cross-on wind.

Friday’s a bit similar. A touch more size in the morning – 3.6ft from the southwest with a 16-second period. But it’s still marginal. The wind is on it, but the whole setup just feels like a bit of a tease. By the arvo, the conditions drop off, turning poor and choppy with a cross-onshore wind.

Saturday stays small, with 3ft southwest swell and a shorter 14-second period. The energy is dropping (595-623), and while the wind is light, the surf just doesn’t have any push. It’s one for the longboard if you’re desperate, but I wouldn't call it exciting.

Sunday is where things start to get messy. A 3ft WNW swell with a blown-out 9-second period arrives, and the wind jumps to a moderate 12 mph from the north, making it choppy and cross-onshore. It’s poor conditions, and not worth your time. By the arvo, it’s lumpy 5ft of the same junk.

Monday kicks up a bit in size but it’s ugly. A 7ft northwest swell with a short 7-second period, and the wind is up again. It’s a walled-up, choppy mess. That's a hard pass from me. The energy is moderate at 682, but the period is just too short to hold any shape.

Tuesday is the same story. 6ft of short-period NW windswell, cross-onshore winds. Poor. Nothing to see here.

Then we hit a bit of a lull. Wednesday the 16th sees the swell drop right back down to 2ft, with a long 16-second period. The morning is marginal, but the arvo is interesting – glassy conditions, light offshore NW wind, and that long period from the southwest. It’s weak, but clean. Keep an eye on that one for a sneaky glassy wave. The energy is only 257, so it'll be small.

Thursday the 17th and Friday the 18th are small and pretty unimpressive. The period is long, up to 21 seconds, but the swell height is down to 1.3ft and the winds are cross-shore. It’s a flat spell.

The weekend of the 19th and 20th is a write-off. Saturday has a bit of swell but it's full of short-period slop, and the wind is up again. Then Sunday the 20th is where the real change happens.

Sunday afternoon rolls in with a proper pulse. The swell jumps to 7.5ft from the NNW, with a short 8-second period. The energy is strong at 1021. This is a lot of water moving, but the period is short, so it's going to be a relentless, heavy closeout at a beach break. This one is for experts only, and even then, it might be a beatdown. Watch for the wind, it's a light cross-onshore but will make things lumpy.

Monday the 21st keeps the size, with 8ft of NNW swell, but the period is still short. The morning is a mess, but the arvo gets interesting. The wind drops right out to a slight air, and there’s a light cross-onshore. The energy is pumping at 1325. It’s big, but the cleaner conditions could offer some heavy, powerful waves for those who know what they’re doing. Still, that short period is a major caveat.

Tuesday the 22nd is the biggest of the run. The swell hits 10ft in the afternoon from the NNW. The energy is very strong at 1331. This is big, dangerous surf, and with a period of only 9 seconds, it’s going to be a washing machine. This is expert territory only, and likely more interesting for
