I think that your guitar is losing moisture and shrinking at the moment. During the summer it will probably take in water and expand.
This would be a good time to learn how to set up your own axe.
Whilst this shrinking and expanding is not dangerous for electric guitars, you will probably need to adjust the action periodically!
