During the summer turn off the hot water heater, it will be cooled by the AC in your home. Use that to mix with the "cold" water and you should be OK.
Basically, you'll be using the hot and cold water taps backwards once you turn off the hot water heater.
Because most water is stored on the roofs here, it gets hot in the sun during the summer. In other countries, the water comes through the water system underground (but not stored enroute) and the earth keeps the water cold.
