Nyoongar Seasonal Calendar

Nyoongar Seasonal Calendar

When rains ease and warm weather starts to take hold, Nyoongars in Western Australia’s south begin to get a feeling for their first summer, more affectionately as Birak. Spanning from Leeman in the north-east to beyond Cape Arid in the south-east, local weather knowledge of Nyoongar country has been recently captured in a seasonal calendar.

Launched on 4 December 2012, the calendar is also the most recent addition to the Bureau of Meteorology’s Indigenous Weather Knowledge website. The calendar which provides a guide to what nature is doing at every stage of the year, illustrates the closely entwined relationships between native flora and fauna in this part of Australia.
