The biggest consideration here is not so much temperature, but the concentration of *electrolytes* in the water.
Ultra pure water has a conductivity of about 5.5 * 10^-6 Siemens per meter. Ordinary distilled water, if exposed to air, will absorb small amounts of CO2 in the form of carbonic acid, increasing the conductivity by about 1 μS/m
The addition of less than 50 ppm of electrolytes can increase the conductivity drastically. Tap water has a conductivity of anywhere from 0.005 S/m, to 0.1 S/m, depending on the level of total dissolved solids (TDS)

Water as it occurs in natureis a conductor of electricity.However pure H20 offers a higher resistance than natural water.
It is almost impossible as a function of temperature to make water an insulator of electron flow.

Specific resistance is not measured in ohms per millimeter (Ohm/mm),
correct dimension is Ohm x mm.

I would say 100 degrees C (212 farenheit). Because then it becomes a gas, and will be a very poor conductor.
Not sure if that's quite what you're getting at, but it seems the most obvious answer.
