Your climate may be on the edge in terms of being a bit hot and seasonally dry, but if you mulched the trees well after the rainy season, European silver birch might be one choice. I have gotten, in rich soils in the northeastern US, specimens that are nine plus meters tall in year eight, from seed. It is the equal of some oak species in terms of firewood, and coppices well. We have hot and sometimes dry summers, and average about the same 100 cm annual precipitation.
