Climate of Charleville

Charleville has a sub-tropical continental climate. In general winter days are mild and sunny and nights are cold. During summer days are very warm to hot and nights are warm. Summer weather is influenced by a semi-permanent trough that lies roughly north-south through the interior of the state. The trough is normally the boundary between relatively moist air to the east and dry air to the west. It is best developed and generates most weather during spring and summer months. The position of the trough fluctuates diurnally due to vertical mixing and from day to day due to interaction with broadscale synoptic influences. The trough often triggers convection with showers and thunderstorms on its eastern side.
