2008 Summary


TEMPERATURE

Mean temperatures were above normal only in Jan, Feb and May, and normal or below in all other months. Indeed Jan and Feb rank among the top 6 years since records began here in 1956.  The annual mean is fractionally lower than expected, although the anomaly rounds to 0.0 deg C. 


RAINFALL

The 997 mm annual rainfall ranks 2nd in our 53 years records, beaten in 1960 with 1030 mm, with last year's 938 mm close behind ranking 4th.  The 153 wet days have only been exceeded in 1960, 1966 and 1977 in our records.

Wettest months were Jul, Aug, Sep and Nov. Each of these months ranks between 4th and 8th wettest in our 53 years records.

The daily rainfall of 34.2 mm on 9/11/2008 ranks 28th in the 9958 days it has rained in our records. Incidentally it has rained on 51.5% of days.

Jan, May also had above normal rainfall but to a lesser extent. The only months with lower than normal rainfall were Feb, Jun and Dec, but in each case the preceeding month has been very wet.

The above normal rainfall during 5 months between Jul and Nov has led to a high water table on our clay soil, and consequently new rainfall has had difficulty draining away.


This has been the only October in our records with snow, albeit only 1cm.
Also it has been the 7th consecutive year with no snow during December.

PRESSURE

1012.7 mean pressure (mb) 
1043.5 max pressure at any time of day on 17/2 
956.5 min pressure at any time of day on 11/3 

The depression which crossed our region on 10th March produced the 
lowest pressure reading of 956.5 mb here in 53 years records.

The 6th wettest July in the last 50 years having 100.9mm (201%) normal rainfall, 
indeed the normal 50mm had been reached by 8th July!
Heaviest daily rainfall was 19.2mm on 28th and 18.6mm on 6th, on both days it was accompanied by thunderstorms.
Overall a cooler month than usual, but warm 1st and increasingly warm from 22nd to 28th, but a cool day 12th.

6th 1430-1530 
7th 1415-1515 
28th 1830-2030 

August was disappointing being predominantly cloudy, wet and changeable.

The 7th wettest August in 52 years record-keeping here, with 19 wet days (>1mm) being the 2nd highest recorded (only exceeded in 1956), and 10 wetter days (>5mm) equalling 
1956 and 1992's record. 

Wettest days were 7th (24.3mm) and 16th (20.8mm).
Consequently the heavy clay soil here became and remained saturated.

A brief thunderstorm occurred at 1750 on 12th with a brief heavy shower.

The temperature range over the month was lower than usual, the highest max temp being the lowest since 1992 and the 9th lowest on record, while the lowest min temp equalled the 7th highest on record.

Overall this gave a mean temperature only slightly below normal.

12th 1750 

A wet and changeable month, starting with 94.8mm of rain between 1st and 6th (equivalent to most of the entire month's normal rain falling between 4th-6th).

This has been the 8th highest September rainfall, also the 8th highest number of wetter days (>5mm) since records began here in 1956.

Although the mean min temp was around normal, the mean max temps was 0.8C below normal, 
making the monthly mean a little low (-0.4C below normal).

The mildest nights were 5th-11th (all over 11.3C).

More settled, warmer and drier with some sunshine between 12th-15th, 
18th-22nd (warmest days 19th-21st, all over 18.8C), and 24th-29th 
(the coolest nights 26th-29th, all lower than 6.7C).

October 2008 November 2008 December 2008

A changeable October with several good sunny days and reasonable temperatures between 7th-13th. 
Very wet (28mm rainfall) on 4th and a further 30mm falling between 25th and 29th, when it turned unseasonably cold. 
Late afternoon of 28th saw 1cm snowfall, the only October snowfall appearing in any October since 1956 here. The night of 28th into 29th recorded a minimum temperature of -3.5C, keeping the partial snow covering on grassy areas frozen into the next day. 

Also a short sharp hail shower (approx 5mm diameter) from 1430 to 1435 on 27th.

Overall rainfall was average, and temperatures 0.8C below expectations.

A mild, cloudy start to November, although a cold but sunny finish.

Mean temperatures overall about normal, but maxima 0.5C below normal,
with the 6th lowest max since 1956 recorded here on 29th, last surpassed
in 1993. 

Minimum temperatures however were 0.6C above normal, the coldest
night being -2.4C on 23rd. In the last decade, 4 Novembers have had a higher min temp than this.

A notably wet month, the 4th wettest November since 1956, with highest
rainfall 34mm on 9th, 24mm on 1st and 18mm on 27th.

There were 4 airfrosts on 1st, 23rd, 26th and 30th, and 2 foggy mornings

2 days with fog (6th , 29th)

December was a notably cold month except for a milder spell 18th-22nd, turning very cold on 31st. 

Only 6 days had a min temp above the normal value.

Only 11 years since 1956 have had a lower Dec mean temperature, although 27 have had a lower low-minimum. Interestingly, because of the mild spell there 
have been only 11 years with a higher high-maximum temp.

Rainfall only 76% of usual, all falling before 20th, so a dry end to the month, consequently only 18 years since 1956 have had lower Dec rainfall.

Many days cloudy and dull with only occasional sunshine, with most sun seen 6th-10th. 

This has been the 7th consecutive Dec with no snowfall recorded, the closest being just a hint of sleet during a brief rain shower on 2nd. Just 1 day with fog on 31st.
