Annette. I hear your plight about going away and leaving things alone. My own opinion will be as follows, listen for others definitely. I would add an extra super, just to be on the safe side, they needs lots of room to store the nectar before it is "turned" into honey. Lots of room. If your temperatures are going to be so high next week, I don't think that the colony will be too chilled to worry about. But again, I do not know your climatic conditions. Maybe others that live closer to you, have more experience with your weather conditions would have better advice, but that is my one cents worth. Best of a beautiful day, good luck, good health. Cindi
