Statistics and Summaries for January 2014

Recommended Posts

Llanwnnen, Ceredigion, Wales

 

Very wet and mild; snowless

 

The very unsettled, mild and wet weather of mid to late December continued almost relentlessly throughout January. This was the wettest January since 2008 (238mm) but the mildest only since 2012 such is the regular recurrence of mild Januaries.

 

1st – 8th: A continuation of the deeply disturbed, wet and at times very windy weather of the second half of December. Plentiful showers and longer spells of rain, very heavy at times. Hail and thunder quite a feature, I have never known 3 days of thunder in the whole of January before and we got that within the first week of this month! Mild or very mild with the SW flow and some strong gusts at times, the highest of the month being 58mph on the 6th. A generally cloudy spell this although 2nd was bright.

 

9th – 11th: A much drier, quieter interlude, Some sunshine with temperatures nearer normal and just a few showers. Air frost on the 10th.

 

12th – 18th: Mostly mild with rain or showers at times, some heavy, but amounts not excessive. Mostly cloudy, although clear spells by night permitted a couple of air frosts. Quite windy.

 

19th – 23rd: Rather cold to average temperatures and some further night frosts. Rain or showers at times, mostly cloudy

 

24th – 26th: Mild, windy and dull with rain or showers, some heavy

 

27th – 31st: Colder but still close to average temperatures, further showers or rain at times, however the 30th was a dry and cold day, the coldest day of Winter to date although the maximum was 3.7c. Fittingly, a very wet and windy finale to January with the 31st seeing 20.7mm rain making it the wettest day of the month.

HOBART ( pop 220,000 ) capital of Tasmania, situated at sealevel at the base of Mt.Wellington ( 1270m ). Climate: Temperate, maritime.

 

January - Second month of summer

Very dry, continuing the theme of the summer. Warmer than average but not spectacularly so.

 

January began cool and it stayed that way for the the first third of the month. Winds fresh to strong W-to more anomalously cool SW, as intense lows passed by over colder waters to the south. Phenomenally windy on 2 days with city wind peak of 65-70mph, causing mayhem and minor 'damage' to property. A front in this wild wind stream on the 5th brought by far the months wettest day ( 8mm ), and further weakening fronts brought just a blustery shower or two that mostly hugged the mountain range.

 

From the 10th-17th it settled, as a severe heatwave came into effect over south-east Australia. This heat penetrated western, inland and highlands of Tasmania but onshore winds and seabreeses in Hobart put a lid on the extreme heat felt elsewhere. Rare phenomena of sea mist moving upriver and coating lower hills during afternoons and mild, muggy nights with low cloud, slow to burn off under the rising sun. The pattern broke with a front late on the 17th with the briefest of thundery showers ( 1mm ).

 

Mild to warm and dry thereafter, then a hot end, as intense heat from the continent returned,  drawn down on a fresher northerly breese, to filtrate at lower depth and to the south east coast, knocking out the seabreese visitor. Scrub fires bringing smoke haze on the hottest day.

 

Average maximum:  23.5 ( +1.3 )

Average minimum:  12.5 ( -0.1 )

Rainfall:  16mm ( average 45mm )

Rain days ( +1mm ) :  3/from 8

 

Extremes in daily temperature for January ( Records since 1882 ):

 

Highest maximum:  38.9 28th ( Record 41.8 in 2013 )

Lowest maximum:  15.6 7th ( Record 11.1 in 1885 )

 

Highest minimum:  18.3 15th ( Record 23.4 in 2013 )

Lowest minimum:  8.6 6th ( Record 3.3 in 1902 )
