You can fly practically at any time of the day or year. In the morning the air is calmer and there are no turbulences disturbing the flight. In the afternoon - especially in summer - it can become a bit more thermally active, but this often allows us to ascend. If this becomes too uncomfortable for a passenger, one can easily leave this upwind and steer in the opposite direction to the landing site. Even in winter you can fly super tandem. The air here is usually very calm.
