In reply to afrosam:
Re Lleida: early June is not exactly high summer but, as others have said, most of the south-facing crags will probably be a touch too warm for "some nice sunny bolt-clipping".
However, the shaded zones, such as Camarasa, Tres Ponts and parts of Fígols and Santa Ana should be absolutely perfect. These are the crags the locals visit once it starts warming up.
The high mountain Granite in Cavallers (single and multi-pitch sport) is also just coming into season at this time of year.
