A great place to learn as it only get waist deep.
Poole Harbour is arguably the Uk's best kite surfing spot. It Is the worlds 2nd largest Natural harbour with endless different kite surfing spots to cover all wind directions with perfect shallow safe waters at all states of the tide. The shallow teaching bay warms up beautifully in the summer making shorts and rash vests a common site. (care of Easy Riders Kiteboarding (http://www.easyriderskiteboarding.com/))
