Some mornings near Seven Presidents Oceanfront Park the wind lies still until about ten, and then the sea breeze comes on and the whole North End drops five degrees. Hawai landscape times the hard part of the day around it — mowing early, then trimming and edging through the afternoon while the air is moving. Yards this near the beach carry sand in the soil and grass that has learned to live with wind, so they get cut a little high in the heat, letting the roots keep their shade. The result is a lawn still green at the worst of August. Small decisions, made every week, add up to that.
