Cooma Weather Forecast & Warnings (2630)

Climate of the Monaro Plains

Cooma is situated on the Monaro Plains at an elevation of approximately 800 metres above sea level. This inland position in the southern part of New South Wales creates a distinct climate characterised by cold winters and warm, dry summers. Unlike the coastal regions to the east, Cooma experiences a significant diurnal temperature range, meaning the gap between the overnight minimum and the daytime maximum can be quite large, especially during the autumn and spring months.

Seasonal Weather Patterns

Winter in the region is defined by frequent frost and occasional snowfalls, though snow rarely settles on the ground for long periods within the township itself. Cold fronts moving up from the Southern Ocean frequently bring brisk winds and low temperatures. In contrast, summer conditions are typically mild to hot. While the heat is less intense than in the lower-lying inland plains of the state, the high altitude results in a high UV index, necessitating sun protection even on cooler days.

Regional Weather Risks

The primary weather risks for this part of New South Wales include severe bushfire conditions during the summer months and extreme cold during winter. The surrounding landscape can become quite dry, making the area susceptible to fire when hot north-westerly winds prevail. Additionally, the region is known for sudden changes in conditions. Frontal systems can move through quickly, causing rapid temperature drops and shifts in wind direction that impact local agriculture and transport routes through the mountains.
