The beach is pretty nice with yellow sand, though that sand can hurt in the summer since it gets very hot. There is usually some trash on the beach (wrappers, plastic cups, picnic trash, etc.). There is tons of space to launch safely or keep your kite on the beach. There is a rock groyne that is downwind when the wind is a northwesterly.
The temperature is blistering hot during the summer June, July, August, September (gets to 50+°C during July and August). Winter (December to February) temperature is about 12-18°C then a wetsuit 2/3mm usually works well in the winter.
There are two wind directions, Northwesterly and Southeasterly. The NW wind is the better one, being stronger and very clean, not gusty at all, and much more common than SE. SE wind is gusty since it blows through the city with all the buildings, not very common wind though.
