Step 1: Think about what a hot, dry summer allows.
A crop that needs little water in summer and can store it in its tissue does well here. Grapevines have deep roots that reach groundwater and thick-skinned fruit that resists drying out.
Step 2: Rule out the water hungry crops.
Rice is a wetland crop and would fail in a dry summer with no irrigation. Wheat and maize can be grown here in the wet winter season but are not unique to this climate; they grow across many climate belts worldwide.
