They should be fine, think of where trees like this grow and you can get quite a variety. African and australian natives are good for your high temps. Things like acacia and african olive will handle those temps with ease. I am bordering zone 11 and have black pines, trident maples, chinese elm and many of the more common trees, the key is adapting and keeping them out of midday sun. And having a more retentive soil mix
