Tasmania in autumn 2014: a warm season

Tasmania experienced a warmer than average autumn. March was a generally warm month overall, although not exceptionally so, and this warmth continued into early April with several sites (including Hobart) experiencing their highest April temperature on record on the 1st. Despite a cooler period during late April and early May, the middle of May saw temperatures again increase as a high pressure system settled over the Tasman Sea, directing a warm northwesterly flow across the State. In particular, 15 May was especially warm about the southeast, with several sites (including Hobart) experiencing their highest late-season maximum temperatures on record. Campania reached a maximum temperature of 24.1 C which is the highest maximum temperature on record so late in the season for any Tasmanian site. This prolonged autumn warm spell affected much of Australia (as detailed in Special Climate Statement 49).

Autumn rainfall was near average overall, although slightly below average about the southeast coast. A relatively dry start to the year continued in the southeast during March, while the north of the State experienced some moderate rainfalls during the second half of the month. Both April and May rainfall totals were near average in most parts of the state, although below average falls were recorded about the northeast during May.

  • Record warm start to April, especially hot on the 1st
  • Record late-season warmth during May
  • A warm season overall
  • Near-average rainfall

Separate summaries have also been prepared for March, April and May 2014.

Notes

A Seasonal Climate Summary is prepared to list the main features of the weather in Tasmania using the most timely and accurate information available on the date of publication; it will generally not be updated. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review, usually published in the fourth week of the month.

A Climate Summary is generally published on the first working day of each month.

This statement has been prepared based on information available at 8 am on Monday 2 June 2014. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages are long-term means based on observations from all available years of record, which vary widely from site to site. They are not shown for sites with less than 10 years of record, as they cannot then be calculated reliably.
The median is sometimes more representative than the mean of long-term average rain.

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, average in decile 4 to 7, high in decile 8 or 9 and very high is in decile 10).
The Fraction of average shows how much rain has fallen this time as a percentage of the long-term mean.
