    HOBART ( pop 215,000 ) is Tasmania's capital city, situated at sealevel at the base of Mt Wellington ( 1270m ). Climate is temperate with a strong maritime influence.

     

    August - Final month of winter

    The 'Roaring 40s' were in full swing for much of the month - embedded fronts in a vigorous westerly airstream crossing Tasmania at regular intervals. Rain and storms in the exposed west, moderating to showers for Hobart in the sheltered southeast. Often windy, with snow settling at times above about the 800m level, lowering to the 400m level on the 20th. It was the aftermath of this colder change which gave Hobart the surprise event of the winter...the lowest recorded temperature for August in 51 years.

     

    A more settled theme developed in the final days of the month, as high pressure reasserted control, moving from central Australia to the northeast of the state, with milder air drawn down from the continent. The temperature rise was significant enough to make this a slightly milder month than average ( 1981-2010 comparison ). Hobart now has not had a below average temperature month since October 2011.

     

    Average maximum:  14.2 ( +0.5 )

    Average minimum:  5.7 ( -- )

    Rainfall:  61mm ( average 54mm )

    Rain days ( +1mm ):  13/from 20

     

    Extremes in daily temperature for August ( Records since 1882 )

     

    Highest maximum:  19.7 27th ( Record 24.5 in 1977 )

    Lowest maximum:  9.8 20th ( Record 5.5 in 1974 )

     

    Highest minimum:  10.3 25th ( Record 15.0 in 2005 )

    Lowest minimum:  -0.4 21st ( Record -1.8 in 1962 )

    England and Wales had the driest and sunniest August since 2007, and the south-east of England was particularly fine for much of the month. It was the warmest August across the country since 2004, although after the hottest day for seven years on 1 August, temperatures were fairly close to average for the rest of the month, though often quite warm in the south and east. This reasonably fine August rounded off the driest, warmest and sunniest summer since 2006.

     
    Temperatures
     
    The mean maximum temperature ranged from 24.4C at Heathrow (London) to 14.4C at Fair Isle (Northern Isles). The Central England Temperature (CET) of 18.1C was 0.6 degrees above average, the highest in August since 2004. Daytime temperatures were within 0.5 degrees of average except in East Anglia and the south-east, where they were 1.0 to 1.5 degrees above. The highest recorded temperature was 34.1C at Heathrow (London) on 1 August, the highest temperature recorded in the UK since July 2006. The month's lowest temperature was 0.2C at Kinbrace (Sutherland) early on 5 August.
     
    Rainfall

    Averaged across England and Wales there was 63mm of rain, which is 87% of the average, though some western areas were rather wet. Nationally, it was the driest August since 2007, but Norfolk and Hampshire were particularly dry. Scotland had 61mm, which is 83% of the average, while Northern Ireland had 74mm, or 104% of the average. The wettest location was Capel Curig (Gwynedd) with 175mm and the driest was Yeovilton (Somerset) with 14mm. The heaviest daily fall was 101mm on the 24 August at Heybridge (Essex).
     
    Sunshine
     
    England and Wales had an average of 189 hours of sunshine, which is 96% of the average and yet it was the sunniest August since 2007, an indication of the indifference of recent Augusts. Scotland was also rather dull with 131 hours, or 87% of its average. Northern Ireland averaged 134 hours, which is 82% of the average. The largest monthly sunshine total was 303 hours at St. Helier (Jersey); 300 hours of sunshine is rarely exceeded around the British Isles.

    The driest August since 1995 and sunniest since 2006. The mean temp was exactly the same as 2009, but together they were both the warmest since 1997. Apart from a few days, maximum temperatures were generally 2-3 degrees either side of average, but the month was generally homogeneously warm. Only 5 days failed to reach 20°C.

     

    The first week was very warm with high temperatures on the first two days. The mean temperature for the first 5 days was 20.3°C. The maxima of 26.5°C on the 1st was actually the warmest in August since 2006 and was rather uncomfortable due to a dewpoint which peaked at 21.0°C - the highest Ive ever recorded. The following night was very warm aswell, with a temperature of 22.6°C at 2am. The minimum that morning was eventually 'only' 18.3°C, but still comfortably the warmest in August since 1991 and only 0.4°C short of the record.

     

    The remainder of the month was generally westerly but very dry. Only 13.8mm of rain fell in the first 23 days. Clear and sunny days throughout were almost non-existent, but days with broken cloud and long spells of sunshine rather common. The final week was then much more settled with cooler nights and fog at times. Temperatures were closer to the average and there was more in the way of sunshine. However the month finished dry again, with July and August combined ending up as the driest since 1976.

     

    Overall, a rather good summer month which was warmer, drier and sunnier than average. Summer as a whole was the sunniest and warmest since 2006 and driest since 1995.
