I'm in Phoenix, and will say that as long as they have water, heat doesn't seem to be an issue. I'm in exactly the situation described above, 110+, and single digit humidity. After the first summer I no longer get leaf burn, I belive due to watering and root development. I've got bananas in full day (east / west) sun, backed by a 10' wall on the north (think massive radiated heat); even at 115, no burning and continued growth. Remember, if these are newer plants, the root base my be very small. Consider shading for the first summer, or just shoot for keeping them alive (don't sweat burned leaves if the pseudo stem stays firm), next summer will be better. If the pseudo stem is soft, be more concerned. Of course all this is IMO, others may not agee, but than again most aren't growing bananas in the desert!
