North Shore

Conditions are improving but remain marginal this morning. The north-northeast swell that dominated earlier this week has declined to a manageable 3–5 feet, and trade winds have eased to around 10–15 mph. Vsibility is slowly returning to sheltered spots. Anini remains the safest and clearest bet in the region, while Ke’e and Haena still have “milky” visibility.

Location Rating Clarity Wind Waves/Surf
Ke’e Beach 4 🟑 Milky NE 10-15 mph 3–5 ft
Haena State Park 4 🟑 Milky NE 10-15 mph 3–5 ft
Hideaways 5 🟑 Hazy NE 10-15 mph 2–4 ft
Anini Beach 6 🟒 Fair / Good NE 10-15 mph < 1 ft

East Shore

Conditions are poor. While the swell has dropped, steady trade winds are blowing directly onshore at 15–20 mph, creating choppy and turbulent surface conditions. A localized Brown Water Advisory remains in effect for the Lydgate to Wailua stretch. Visibility is very low due to wind-driven churn and active river runoff.

Location Rating Clarity Wind Waves/Surf
Lydgate Park 2 πŸ”΄ Murky NE 15–20 mph 3–5 ft

South Shore

The South Shore offers the best snorkeling on Kauai today. It is well-protected from the remaining northern energy, with small, clean surf at 1–2 feet. Clarity is high at both Poipu and the Beach House, though the freshening trade winds may create minor surface ripples by midday.

Location Rating Clarity Wind Waves/Surf
Poipu Beach Park 8 🟒 Clear ENE 10-15 mph 1–2 ft
Beach House 8 🟒 Clear ENE 10-15 mph 1 ft

Marine Advisories

  • Brown Water Advisory: A statewide advisory remains in effect for Kauai. Additionally, a localized advisory is active for Nawiliwili to Kalapaki Beach and Lydgate to Wailua. Avoid any water that appears brown or turbid.
  • Small Craft Advisory: Trade winds are beginning to weaken, but hazardous seas and winds persist in open channels and windward waters.
  • UV Index: Very High (10). Wear reef-safe sun protection and stay hydrated.

Legend

  • 8–10 🟒 (Excellent): Safest conditions; high visibility; calm surface.
  • 5–7 🟒 (Good/Fair): Generally safe; visibility may be limited by surge or runoff.
  • 1–4 πŸ”΄ (Hazardous/Poor): High surf, dangerous surge, or brown water. STAY OUT.

Best Time to Snorkel: Between 8:30 AM and 11:30 AM. This window precedes the strongest afternoon trade winds and avoids the low tide at 10:14 AM (Nawiliwili), which can expose shallow reef heads.

Ocean conditions can change rapidly.Β  Watch the surf, waves, currents and surge on the shoreline, rocks and reefs. Always spend a few minutes (5-10) in snorkel meditation watching the conditions.Β  Savor the moment.Β  If the water doesn’t look clear, calm and inviting, don’t go in!
