Here's how the next 5 days are shaping up at Eureka, Northern California. Each day is rated based on breaking wave height, swell period, and wind — updated hourly from the latest NOAA GFS run.
Wed, Jun 24: 3–4ft, 18s period, rated Poor - Fair. Pretty quiet out there — 2-3ft and mostly poor - fair with glassy conditions.
Thu, Jun 25: 3–4ft, 18s period, rated Poor - Fair. A slow one — 3-4ft waves and poor - fair conditions with moderate N wind around 9mph.
Fri, Jun 26: 2–2ft, 16s period, rated Poor. Early morning is your best window — 1-2ft waves on NW swell at 6s with light winds out of the SW. The NW wind kicks in by afternoon — 7mph and poor by then.
Sat, Jun 27: 4–5ft, 15s period, rated Poor - Fair. Aim for the middle of the day — 4-5ft on WNW swell at 9s with light NNW winds. It's a bit wonky first thing but settles down. Afternoon wind picks back up so try to get wet before 2pm.
Sun, Jun 28: 5–6ft, 10s period, rated Poor - Fair. Get out early for the best of it — 5-6ft waves on WNW swell at 9s and glassy conditions. The NNW wind kicks in by afternoon — 11mph and poor - fair by then.
Eureka's beach breaks offer the most accessible surf near Humboldt Bay, with sandy bottoms and relatively consistent peaks from W and NW swells. While the waves can be mellow, the standard NorCal conditions — frigid 52°F water, sharks, and strong currents — make this intermediate territory. One of the more approachable spots in the Eureka area for experienced surfers visiting the region.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Eureka is 3-4ft with a 17.8s swell period. Wind is N at 7mph and conditions are rated Poor - Fair. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Eureka is 3-4ft, produced by a 3.7ft NW primary swell at 7s, a 1.3ft SW secondary swell at 14s, a 1.1ft SW tertiary swell at 18s. Breaking wave height is the actual rideable wave size at the shore — calculated from offshore swell data using this spot's coastal bathymetry — not the raw buoy reading.
Based on the current 5-day forecast, the best window to surf Eureka is Sunday from 6 AM to 9 AM with 5ft waves, a 9.05s swell period, and conditions rated Good. Check the hourly forecast for updates as conditions can shift.
Eureka works best with a W swell and E winds. Offshore winds groom the face of the wave, while onshore winds turn it sloppy. Cross-offshore conditions usually produce the cleanest shape.
Tide plays a big role at Eureka. Mid tide works for most beach breaks, while reef and point breaks often prefer higher or lower stages. Use the tide chart above to line up your session with the swell peak.

Common hazards at Eureka include cold water, sharks, strong currents, fog, rip currents. Always check conditions before paddling out, respect local etiquette, and never surf alone if you're unfamiliar with the break.
Our Eureka forecast uses NOAA GFS and other weather models combined with spot-specific bathymetry to calculate breaking wave heights. Short-range (1-3 day) forecasts are most reliable. Extended forecasts show general trends. Visit /public/accuracy for per-spot and regional performance metrics.
