I was talking to a couple of dive instructor's today , they were complaining about how cold the sea was . Normally it is around 31-32 degrees around Koh Chang but now it around 25-26 degrees which got me thinking about the cooler weather over the last 2 months . Are they connected in some way ? I was wondering if there is an Artic current that streams into the gulf of Siam or is it just influenced by the weather patterns ?

My pool has refreshing 21°C atm, need 5 min less for my daily routine - leaving the pool covered with goosebumps, nice.
