These reports help determine at what temperature formation can begin and when soils are too cool to form mushrooms in an area. Forecasts are based on temperatures down loaded from each area. Each forecast location indicates what general temperatures in the area and not specific temperatures in areas where matsutake grow. A temperature of 60 degree in one area may indicate formation is possible, where as in another area it may be 55 degree.

Rise in temperature is also important to determine volume of crop formed. Too little rise will not form mushrooms. Too much rise will cause forming mushrooms to burn and die or not allow mushrooms to form. Generally a 3 to 10 degree rise is needed. 5 to 8 degree rise is generally ideal.
