June 2013


Dry with near average temperatures


With just 2 inches rainfall this was the driest June since 2010 (41mm), only one day having above 10mm (13.6mm 27th). A warm, dry and sunny first 10 days, was followed by a changeable pattern of westerly winds and some rain at times. Nothing terribly spectacular temperature wise either, although it dropped to below 2c on the 25th with a late grass frost.


1st – 10th: Dry, very sunny and warm/ very warm. High pressure over or close to the UK, plentiful clear skies and sunshine for West Wales compared with the East! The first two days were cool but then maxima were between 20c and 25c. Several days had virtually unbroken sunshine. Nights were cool even with grass frosts 2nd to 4th.


11th – 16th: Atlantic lows brought much cooler and changeable conditions, rain or showers at times, and strong winds at times too, especially 14th.


17th – 19th: Rather warm and mainly dry with sunny spells.


20th – 23rd: Unsettled with some rain or showers at times, but no large amounts, became quite cool and windy over the weekend of 22nd / 23rd.


24th – 26th: Dry with sunny spells and near average temperatures, chilly nights.


27th: - 28th: Unsettled with rain at times, a little sunshine


29th – 30th: Dry with some sunshine, not so warm though.

June 2013 in YATTON, North Somerset:

Very similar to SteveB being just up the road. June was overall an average and rather boring month. The most remarkable weather was the concentration of unbroken sunshine in the first week. By the second week it had turned more unsettled with dribs and drabs of rain, the most significant coming from a line of heavy showers on the 15th. The warm and humid spell in the third week provided more in the way of sunshine than in many other places but failed to deliver any notable temperatures or thunderstorms. The final week was predominantly cloudy apart from unbroken sunshine on the 25th and lengthy spells of sunshine on the 29th. Fortunately, the unsettled spells haven't produced anything like the amount of rain of June 2012 or, to lesser extent, June 2011.

The first summer month with above average sunshine since July 2009 and the first since July 2006 to be both drier and sunnier than average,

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.


June - First month of winter

This was one of the warmest starts to a winter on record, with a mean temperature of more than +3C up until the 12th. Mild and dry air from the continent then shifted rather cold SE'ly, as a low pressure system formed in the Great Australian Bight, moved eastward, and then amplified over waters to Tasmania's north-east. With moist winds coming straight off the sea, a week of wintertime murk began with low cloud that enveloped the lower hills, with frequent showers and drizzle, some heavy at times. Light snow settled on occasion to above about the 1100m level. Days were 1 or 2 degrees below average and nights were 1 or 2 degrees above average due to extensive cloud cover . As the low barrelled off toward New Zealand, the trailing high established itself just off Tasmania's south coast which is its rarest position to be in,  and a week of frigid temperatures began. As skies cleared and wind speeds died off, overnight temperatures plunged to near zero ( but -5 to -10 inland ), and days struggled to warm under a persistent inversion layer with morning fog, despite sunny skies. This week proved to be the coldest in terms of mean temperature for 21 years in Hobart. As the month drew to a close milder air infiltrated from the west-north west.


The warm start dented the chance of this being a colder than average month. So this makes it the 20th month in a row in which mean temperature in Hobart has exceeded average ( 1981-2010 average ).


Average maximum:  13.0 ( +0.6 )

Average minimum:  6.1 ( +0.8 )

Rainfall:  51mm ( average 53mm )


Extremes in daily temperature for June ( Records since 1882 )


Highest maximum:  18.8 ( Record 20.6 in 1907 )

Lowest maximum:  7.9 ( Record 4.3 in 1985 )


Highest minimum:  10.5 ( Record 14.4 in 1957 )

Lowest minimum:  0.2 ( Record -2.8 in 1972 )

Rainfall: approximately 25mm (Reading University site) - around 50% of average

Sunshine: approximately 190 hours (Reading University site) - close to average.


A dry month with near average temperatures and sunshine.  The first week was fine and sunny with cool nights, the middle of the month was generally rather cloudy and often humid with some rain which mostly fell overnight and the month ended with a warm and sunny weekend.  25 deg C was reached twice during the month - the first time it was reached this year, on 19 June, was unusually late.

The coolest June since 1997 and the lowest mean minima since 1996. Despite a mean maximum not too far from average, only four days surpassed 20°C and the highest temperature on the final day was the lowest high maximum in June since 2007. It was also the 11th consecutive below average month.


The month started predominantly settled with easterly winds. The first 7 days were very sunny but the sea breeze meant it was rather chilly. The mean max to the 10th was just 15.2°C and average temperature 11.5°C - the coldest since 1991. It was then almost constantly overcast for the period 8th-10th. Due to the anticyclonic weather it was at least very dry, with just 0.4mm in the first 11 days.


The dry weather changed spectacularly on the 13th as a thunderstorm brought 16.2mm of rain with a maximum rainrate of 225mm/hour, the highest Ive ever recorded. It caused localised flooding and power cuts. The following day thunder was heard again, but every shower missed this area and we saw just 0.2mm of rain. The changeable weather continued for the next couple of weeks with a mixture of dry days and occasional periods of rain. One consistent feature however was the lack of sunshine, with little in the way of clear weather. Even when the weather turned more settled in the final week, sunshine levels were still disappointing and as a result, despite being close to average sunshine overall it was still duller than 8 Junes in the last decade.


Overall, a pretty average affair here so close to the east coast, with supressed temperatures and less sunshine than areas further west and inland enjoyed.
