July: The Buck Moon
Buck deer start growing velvety hair-covered antlers in July. Frequent thunderstorms in the New England area also resulted in the name Thunder Moon. Some tribes also used Hay Moon.
The Full Buck Moon – July July is normally the month when the new antlers of buck deer push out of their foreheads in coatings of velvety fur. It was also often called the Full Thunder Moon, for the reason that thunderstorms are most frequent during this time. Another name for this month’s Moon was the Full Hay Moon.
