What should be the maximum allowable water temperature

Of all the open water swims around the world, is there a race where there is a maximum allowable water temperature? If so (or if not), what is the scientific information or medical guidelines for a maximum allowable water temperature for open water swims (non-wetsuit)?

    Well, according to our boat captain, the water temp at the official "Swim around Key West" in June was 91. I would NOT recommend that to anyone! I did only 4.5 mile on a 3-man relay.....I could not wait to get out. I don't know how the solo swimmers did it, I really don't. Most of my OW swims are in 80-86 here in the SE. I swam the solo, and I have to say that whatever the water temp was it should be considered beyond the range of what is allowable for a multi-hour competition. I thought the temp was higher than 91, though, that number seems a bit low but you measure was probably more official than the temps that were quoted to me. I experienced heat exhaustion symptoms around mile 10. I can easily see how someone might pass out under those conditions.
