February Conditions at Kalihiwai Beach
February Advisory Risk Moderate-High

🌧️ Rainfall & Runoff

February is part of Hawaii's wet season (October through March). Kalihiwai Beach sees approximately 5.2 inches of rain this month. Heavier rainfall means more runoff entering coastal waters, carrying bacteria from inland areas. Streams and storm drains near the beach can discharge after rain events.

📌 February Notes
Humpback whale season is active (November through April). Whales are frequently visible from shore across all islands.
North Shore surf competitions may close certain beach areas. Check local event schedules.
If It Looks Brown, Don't Swim
Never enter the ocean when the water appears brown or murky, even if no advisory is posted. Hawaii is often slow to test beaches and update advisories — not every beach is monitored. After heavy rain, wait at least 72 hours and until the water clears before swimming.
