The heat accumulation above this base temperature is reported as growing-degree days (GDD). For cereals and oilseeds this temperature is 5ºC and for corn and sorghum the temperature is 10ºC. The accumulated heat above the base temperature is added together for the growing season to determine the GDD.
The heavy intensity rainfalls often occur during July and August in association with hot weather. The Parkland region will tend to be slightly cooler and wetter than in southern Manitoba. The average number of frost-free days varies in the region from 90-112 days. The number of frost-free days is particularly reduced in the western areas due to the escarpment or increased elevators of about 700 and 800 metres high around the mountains. Snowfall is also important as a source of spring soil moisture and as an insulating blanket protecting soil temperatures from extreme and wide temperature fluctuations.
