Okay, this is the thing with Florida at this time of year. Yes, it can be warm enough to swim, and usually is. The last two days it was cool, but they said on the news that we were close to breaking a record for a cold temperature. It is currently 64 degrees, tomorrow the high is supposed to be 75 high, 61 low. Averages for October is low 61 - 65, average high is 80 - 81, that is for the last 2 weeks of October based on historical records. Today was shorts and tee shirt weather in the parks. There have been kids in the pools, but not me. Sunset, well, Saturday is the daylight savings change, but before that - as in now, dark is about 7. by October 31st, (after DST) sunset will be 5:41. hope that helps.
