Mean monthly minimum temperatures are generally below average by around 1°C although some parts of the southern Lower Western District are below average by more than 2°C. See Map 4. A note about deciles: Deciles are used to give an element (in this case rainfall) a ranking. Deciles are calculated by arranging the totals in ascending order (from lowest to highest) then splitting them into 10 equal groups (thus the groups are called deciles). The first group would be in decile range one, the second group in decile range two, etc up to the highest annual totals (highest 10 per cent) being in decile range 10. Further information:
