Kealakekua Bay is looking like its usual pristine self today, ready to show off its vibrant reef and playful dolphins. Light 2.9 mph WSW cross-shore winds are keeping the surface calm, which is great for this west-facing bay, though the rising tide is the main factor to consider. The estimated visibility today is 50-60 ft, offering excellent views of the marine sanctuary's abundant life despite the minimal 1-2 ft surf.
