I have experienced the exact same problem, and I don't believe that it is particularly uncommon. Because the thermoswitch that triggers the fan relay is itself triggered by the underhood ambient temperature, hot climates play havoc once the car is parked. The sensor is mounted relatively high on the fan shroud, and that area doesn't cool down quickly if the car is sitting in a parking lot, hot-soaking (the fan's influence, notwithstanding). As others have suggested, make sure the relay isn't getting sticky. Otherwise, a tip-top cooling system will make a difference - if the engine runs a bit cooler, then the underhood temp will be reduced somewhat. A few suggestions:
1. If you have the European narrow-bladed fan on the car, swap it out for the standard fan.
2. Make sure that all cooling-related items are in good shape: radiator, thermostat, water pump, etc.
3. Add a bottle of Redline Watter-Wetter to your cooling system - this product is worth every penny!
If the foregoing does not help, then perhaps you could try relocating the thermoswitch to a location lower in the engine compartment.
Good luck!
