The heat and humidity of summer can be some of the most stressful of times for the sheep and their shepherd, second only to the stresses of the lambing season. The most dangerous times are when the temperatures suddenly soar (with no gradual increase in temperature). This does not allow the sheep to adapt to progressively warmer weather. The danger comes when the temperatures stay in the 80-90-100 degree range, there is high humidity and it does not cool off at night.
