Even our usually calm Hanauma Bay is feeling a bit feisty today, with conditions leaning towards the poorer side of fair. That 3-4 ft swell is pushing in, and while the crater walls offer some protection, it's still stirring up the reef, compounded by a brisk 16.1 mph ENE cross-shore wind. The estimated visibility today is 20-30 ft, a bit murkier than usual for this protected spot.
