By August the rain has its own schedule here — thunderheads stack up over the Everglades in the early afternoon and are overhead before anyone has moved the car. Grass in Hallandale Beach answers that weather by putting on a week of growth in four days, and Blue Sky Lawn Services LLC plans the route around it, cutting early and cutting often so nothing gets away. The mower rides a little higher in the wet months; a taller blade shades its own roots and keeps the color deep through the heat. Along the ballfields and side streets near Peter Bluesten Park the trimming follows fence lines and utility poles until the yard has an outline again. After the storm passes, the whole block smells like cut grass and warm pavement.
