Summer is nice and warm. High season a shorty is ok, a few weeks with just shorts is possible. Usually a wetsuit is always needed. Water max 22°C in summer, normally around 15°C. Winter gets cold, but a thick wetsuit, gloves, mask and shoes make kiting almost year-round possible. Air: summer between 20-30°C, spring and fall around 15°C.
From Bremen take A28 to Emden. Here take B210 towards Aurich and before Aurich take B72 to Norden and Norddeich. Here take a boat/ferry to Juist. No cars allowed on Juist.
