What Sailing Gear to wear on Dublin Bay in July?
Given an air temperature on the bay between 12 and 24 degrees Celsius and a 12 degrees average surface water temperature, youth sailors on Dublin Bay in July would normally wear at least a wetsuit with a spray top.
See figures for Dublin Airport in the attached table. Note, out on the water on Dublin Bay is usually a couple of degrees cooler.
