It's getting a bit hot to be outside now. But this year has been a lovely long winter. The climate has been almost Mediteranian since November. There is plenty of sport for them, and plenty of clubs to join. Football and the likes gets played at night during the warm season. There is a good size ice rink (although I don't know if it is open or not at the moment), and I highly recommend the sailing clubs. They are great for all ages. Equestrian activities are also available. You will find plenty for them to do.
