Boonal Weather Forecast & Warnings

Regional Climate Characteristics

Boonal is situated in the North West Slopes and Plains region of New South Wales, a geographic area characterised by a humid subtropical climate that transitions into a semi-arid zone further west. This latitude band typically experiences warm to hot summers and cool, crisp winters. The proximity to the Macintyre River system means that local humidity levels and fog patterns can be influenced by the surrounding riverine landscape, especially during the autumn and winter months.

Seasonal Weather Patterns

During the summer months, the area is prone to significant heatwaves as inland air masses dominate the region. These high-temperature periods are often broken by afternoon thunderstorms, which can bring heavy localised rainfall and occasional hail. Because Boonal sits in a transition zone, it can be affected by the tail ends of tropical troughs moving down from the north, as well as the inland penetration of moisture from the Tasman Sea.

Severe Weather Risks

Like much of inland northern New South Wales, the primary weather risks in this region include bushfires during the dry spring and summer periods and flooding during high-rainfall events. The flat topography of the surrounding plains means that runoff from the Great Dividing Range to the east can lead to riverine flooding even if local rainfall is not extreme. In the cooler months, heavy frosts are common as clear nights allow heat to escape the soil, a critical factor for local primary producers and travellers on regional roads.
