My experience is that the critical issue for firm greens and fairways is precipitation, not temperature. It may be that Monterey has mild summer weather, possibly with high relative humidity. But, does it rain? My understanding is that there is negligible rain in May and June in this area (I could be wrong, as I have only visited for the odd day in summer). The weather forecasts certainly say that for San Francisco.
If I am right, then Monterey (and any other North Californian coastal courses) would be prime candidates for 'firm and fast'. All that is needed is control of the pump house. Turf shouldn't be lost to heat stress in a NorCal summer, should it?
