In West Gippsland, the major influence on climate is the easterly movement of high and low pressures systems and southerly movement of low-pressure systems off the east coast of southern Australia. The region has a Mediterranean climate with maximum temperatures and minimum rainfall in summer. This is tempered in coastal areas and the east of the region by frequent coastal depressions, creating milder temperatures and a more evenly distributed annual rainfall. Droughts are often experienced from mid-October to late April.
The climate varies with elevation, topography and distance from the coast. Lowlands tend to be warmer and drier, changing to cooler, wetter highlands. The Gippsland Plains are topographically uniform and show little variation in climatic conditions compared with mountain areas.
