HH Water Temp

[DebDisney]

When does it start getting too cold to get into the water at the HH beach? We currently have a reservation for the first week of October, but it looks like we're going to have to push it out due to a conflict (hopefully something will be available). Anyway, I don't want to go so late in the year that we can't get in the ocean, so if anybody knows about the water temperature, I'd appreciate the input.

Thanks!
