Blue skys and dragonflies - Northern Territory in April 2007

Summary

April was a wet season month in name only for most parts of the Territory in 2007, with the monsoon trough staying north of the north coast throughout the month. Away from the north and east of the Top End, little or no rain was reported. With the dry conditions came warmer days over most parts.

Rainfall

Virtually no rain was recorded south of the Victoria River to Gulf country region in April. Even in the north, rainfall was below average, though perhaps typical of an April not under the influence of monsoonal conditions.

Temperature

Drier conditions promoted warmer than average days in most parts of the Territory. Overnight temperatures were also warmer than normal in the far north and south, with near-to or below average temperatures over central to western parts of the Territory.
