Isle Royale Temperatures

I found this on some weather site a couple of years ago--and it seems to be fairly consistent with my own Isle Royale experiences.

Some people pack and prepare for the "average" temps and precipitation. I come prepared for the possibility that a new record temperature could potentially be set while I am on the Island... especially a record low temperature.

Let's use August for example. The average LOW temperature is 52 degrees. Well, the "record" low for August is 34 degrees --and I have seen a small thermometer (that I had with me) show a reading of 32 degrees one August morning. When you are hiking and carrying everything on your back--it sure feels nicer and lighter to be prepared for an average low of only 52 degrees. HOWEVER, on an early August morning,--when your thermometer reads 32 degrees--you will be mighty glad that you brought the right layers (that you can combine) --and the right sleeping bag or quilt--to help you deal with the reality of that 32 degree temp.
