Strawberries in Mediterranean Climate

I live on Crete zone 10a and our summers are very hot and dry which = unhappy strawberries. I'm trying to figure out what I could do so they would have lots of light and sun exposure during the winter and spring when they're producing, and then maximum shade during the scorching summers. I need a dense overstory plant canopy to shade them that would only be there in the summer...any ideas?

I would recommend selecting a variety that is heat tolerant.

Plant them with morning sun and afternoon shade.

Make sure that the strawberries get watered and do not dry out for long periods of time.

My climate is described as "Mediterranean" and strawberries have really well in the garden until last year when we had severe drought conditions.  Half the already low average rainfall, which saw Eucalyptus trees looking very sick, thyme and tarragon just giving up - you get the picture.  
I'd suggest making waterwell containers - that ensures that the plants will get what water they need - as long as the water is topped up (I forget sometimes but the plants look a bit limp as a reminder)  If the containers are portable like icecream containers or broccoli boxes etc, then they can be loaded onto a wheelbarrow and moved according to where the sun/shade ratio is the best.  Good luck, strawberries are the best!
