Banking hours are Monday - Friday 8:30am - 3:30pm.
It is possible to have money wired directly from a bank in your home country to a bank in Koh Samui. It normally takes two - five working days to arrive, and costs around US $40 per transaction. Western Union - has an agent located at the Bangkok Metropolitan Bank in Nathon. This is the fastest but most expensive way to send money.
