It could be many things, hard to comment without being able to do some basic diagnostic tests. Check the coolant level is OK, after that the most likely causes are a cooling system thermostat that is not fully opening, a partially restricted radiator,a mildly blown head gasket or cooling fan that is not operating correctly.
