North Shore Conditions 🟡
| Location | Rating | Visibility | Wind Speed | Waves | Currents |
|---|---|---|---|---|---|
| Ke’e Beach | 6.5 🟡 | Fair AM / Outer Reef Surge & Sand Murkiness | E 10-15 mph Trades | 3 ft Declining NNW Swell | Moderate Outer Lagoon Drift |
| Haena State Park | 6.5 🟡 | Fair AM / Ledge Surge & Whitewash | E 10-15 mph Trades | 3 ft Declining NNW Swell | Moderate Reef Surge |
| Hideaways | 6.0 🟡 | Fair AM / Ledge Surge & Sand Murkiness | E 10-15 mph Trades | 3 ft Declining NNW Swell | Moderate Ledge Surge |
| Anini Beach | 7.5 🟢 | Good Inside Protected Lagoon | E 10-15 mph Trades | 1-2 ft Inside Wrap / 3 ft Outer Reef | Low Inside Lagoon |
Description: The previous north-northwest swell continues to ease down to 3 ft along North Kauai today before a fresh swell arrives Friday. Strengthening easterly trade breezes (10-15 mph) build moderate surface texture, while residual northern set waves maintain light ledge surge along open entries at Ke’e, Haena, and Hideaways. Anini’s broad outer barrier reef blocks the ocean energy, providing good viewing inside the lagoon.
East Shore Conditions 🟡
| Location | Rating | Visibility | Wind Speed | Waves | Currents |
|---|---|---|---|---|---|
| Lydgate Park | 6.5 🟡 | Fair Inner Pond / Light Outer Wall Ripple | E 10-15 mph Trades | 2-3 ft Trade Windswell | Moderate Outer Wall Drift |
Description: Strengthening easterly trade winds (10-15 mph) create light surface chop along windward shores today. Lydgate’s boulder-enclosed ponds offer a secure swimming area, though minor ocean movement spilling over the outer barrier wall keeps clarity in the fair range.
South Shore Conditions 🟡
| Location | Rating | Visibility | Wind Speed | Waves | Currents |
|---|---|---|---|---|---|
| Poipu Beach Park | 6.5 🟡 | Good/Fair AM / Low Shorebreak Surge | E 10-15 mph Offshore Trades | 1-2 ft Small Long-Period South Swell | Low Shorebreak Backwash |
| Beach House |
6.0 🟡 |
Good/Fair AM / Light Ledge Surge | E 10-15 mph Offshore Trades | 1-2 ft Small Long-Period South Swell | Light Ledge Surge |
Description: South Kauai snorkeling conditions are decent today. A long-period south swell is slowly filtering in, but set wave energy remains small at 1-2 ft. Offshore trade breezes maintain smooth water surface conditions along Poipu Beach and Beach House entries, yielding clear morning visibility.
KEY LEGEND
- 🟢 (7.0-10.0) Good: Safe, clear water, low surge.
- 🟡 Marginal: Fair visibility, light surge. Use caution.
- 🔴 (0.0-3.5) Dangerous: High surf, strong currents, or turbid conditions. Avoid.
BEST TIME TO GO: Head out early during the morning window (7:30 AM to 10:30 AM) to South Kauai beaches (Poipu Beach Park, Beach House) or Anini’s protected inner lagoon for peak clarity before trade winds strengthen in the afternoon.
MARINE ADVISORIES: The previous north-northwest swell continues declining to 3 ft today before a new swell arrives Friday. A new long-period south swell (18-19s) slowly builds today into Friday. East-northeast trade winds strengthen to 10-15 mph statewide.
Ocean conditions can change rapidly. Watch the surf, waves, currents and surge on the shoreline, rocks and reefs. Always spend 5-10 minutes in snorkel meditation watching the conditions. Are there other snorkelers in the water? Savor the moment. If the water doesn’t look clear, calm and inviting, don’t go in!
