Thermal mass is good but only works if shaded during the hot weather. Otherwise it will heat up to buggery and cook your plants even better.
I'd be thinking of open-canopy trees to solve this problem, i.e. those that will give a little bit of shade but not too much. Deciduous if possible to still get all the winter gains you talked about. However they are not an instant solution

just a thought,
a thermal mass (like a very big rock/stone, or waterbody/pond) will temper extremes: when hot, it aborbs the heat; when cold it will radiate warmth.
