Northern Territory in January 2008

Hottest on record in the Territory.

Summary

Southern parts of the Territory experienced extreme heat this January. Several meteorological recording stations reported a monthly average maximum temperature in excess of 40°C, exceeding previous records. The Northern Territory as a whole recorded its hottest area-averaged maximum and minimum temperatures for any January since comparable records began in 1950.

The month began with an active monsoon trough in the north. Tropical Cyclone Helen crossed the west coast of the Top End near Channel Point on the evening of the 4th, bringing gale force winds to Darwin and widespread heavy rainfall to many parts of the Top End, especially the Adelaide River catchment. A week later Darwin recorded a remarkable deluge when 212 mm of rain fell in a 2-hour burst overnight. The monsoon event subsequently waned and did not directly impact southern parts of the Territory, which as a consequence, experienced mostly clear skies, little rain and hot days.

Rainfall

Much of the rain that fell in the Territory was associated with the monsoon event that started in late December and continued in to early January. This included the landfall of Tropical Cyclone Helen on the west coast of the Territory's Top End on 4 January. See the information page on TC Helen. While areas of inland Queensland experienced flooding, most areas south of the Top End in the Territory remained dry until the last few days of the month, when thunderstorm activity resulted in some falls.

The wettest overall was 515.2 mm at Darwin Airport

The wettest single day was 242.0 mm at Darwin Airport on the 13th

Some sites had their highest daily January rainfall on record.

Some sites had their lowest total January rainfall on record.

Maximum temperature

When averaged over the whole of the Territory January 2008 was 2.7°C above normal, the hottest January since comparable records began in 1950. This was principally due to the sweltering conditions in the southern half of the Territory, where several new extreme temperature records were established.

Notes

This statement has been prepared based on information available at 12 pm on Friday 1 February 2008. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

The Rank indicates how rainfall this time compares with the climate record for the site, based on the decile ranking (very low rainfall is in decile 1, low in decile 2 or 3, normal in decile 4 to 7, high in decile 8 or 9 and very high is in decile 10).
The Fraction of normal shows how much rain has fallen this time as a percentage of the long-term mean.
