Probably a virus: Viruses often cause fever at night and not during the day. You may have had a viral illness over the weekend that is now resolving. Make sure you drink plenty of fluids, it is important to stay well hydrated when you have a fever. If you have aches and/or pain, acetaminophen (Tylenol) will probably help you to feel better even if you do not currently have a fever.
