Varies from 50's to teens. Cold rain, possible snow.
It is open year round. I camped there back in January and it was 17 degrees. Snow and other winter conditions are not uncommon. Enjoy.
As posted on their website, the day use areas are open Dec-Feb from 7AM to 7PM. Please be aware that if you plan to camp at Lake James the entrance and exit gates are only open during the Day Use Hours posted and are locked with no way in or out at all other times. So they are locked for 12 hrs of your day. Be sure not to go out for dinner because if you arrive back after 7PM there will be no way in this park.
