Egypt is one of the top kite and windsurf destinations year-round, due to the reliable wind especially in the summer as well as extended flat and shallow lagoons. During winter, you usually have better conditions in the south (>70% windy days), whilst April - October, the area around Hurghada and the Sinai offer the better wind statistics (60%-80% windy days, June until September even >80%).
I was lucky enough to spend two weeks in Wadi Lahami with Thilo and his lovely team. Thilo was very supportive regarding any questions prior to the trip - and I had many as it was my first kitevacation... The spot is great, beginners as well as more experienced riders will find fantastic conditions, have heaps of fun and improve their riding. Plus there is plenty to do if the wind should take a short break. I highly recommend this trip to anyone who isn't looking for a party crowd but for some great quality time with great people - guests and team alike.
