See these studies: 

Hoegh-Guldberg et al. 2005. Coral bleaching following wintry weather. Limnol 
Oceanogr 50(1): 265-271. 

Saxby et al. 2003. Photosynthetic responses of the coral Montipora digitata 
to cold temperature stress. Mar Ecol Prog Ser 248: 85-97. 

There are others, but I had those handy. I doubt it will get cold enough to 
cause bleaching, especially if it stays above 18 (which it most likely will 
in most areas). I don't think one will see bleaching due to cold except in 
very unusual circumstances (e.g. low tide and cold air, prolonged, unusual 
upwelling). Someone else may know better than I, but the acroporids are 
likely going to be the least cold-hardy whereas Porites is probably amongst 
the most.
