Hurricane Danielle's effects

This morning seemed to offer ideal conditions for doing what these three were doing at Bay Shore (standing on a board with a paddle), what's this activity called?

The tide was at the low point and although the surf wasn't what the folks at Lawrencetown Beach outside Halifax were enjoying, it looked like a fun time.  It's not so often that Bay Shore offers a warm breeze, and slightly warmer than usual water temperature.
