Figure 3 illustrates some aspects of the climatic diversity present in north-eastern Australia. The climate of eastern Cape York Peninsula is typified by rainfall and temperature data recorded at the township of Coen. Mean monthly maximum temperatures rarely fall below 28°C and mean monthly minima drop below 20°C only during the period June to September. Very little rainfall occurs over the period April to November. The period of greatest rainfall is related to the development of the southern monsoonal trough and most occurs in association with the passage of tropical cyclonic weather systems.
