If a pool is listed as open during the winter, it is a pretty safe bet that the pool is heated because it does get cold here. Or, see the chart below for a list of pools that are open during the winter months. If you’re unsure, contact your hotel directly. Some also close for a short time during the winter for maintenance. Those that do close are usually only down for a few months during the colder season for Vegas (November – February). While most Las Vegas pools are heated nowadays, some do close for the winter months between mid-October to mid-March. The main pool at the MGM Grand is open and heated to 80☏ during the winter months.
