sorry to do this but it amuses me when people read a temperature to a whole degree and then give the averages to 2 decimal places!

Well John, with all due respect to you experience, that's the way I do it.

If you have any number of random whole degree figures and then work out an average it's going to be read to XX decimal places. I seem to recall you once telling me that I should do things to 2 decimal places.

It's similar in cricket ; a batsman scores, say, 34, 56, 0, 117 and 21. His runs total is 228 and his average is 45.60 because when working out an average you seldom get a whole number.

[johnholmes]

don't remember me saying it should be to 2 decimal places, I go on often enough about any met average should be to 1 place only, the same accuracy as any of us can read a thermometer, or with a digital its almost always to 1 decimal place.

But no problem, I do it the Met O way, you and others, its up to you what you choose.

[Summer of '47]

January 2008 turned out to be almost as mild as Jan 2007, but not quite, and virtually frost free. It was dominated by the Atlantic LPs with HP often lying to the south and southwest with mild and windy weather resulting. The monthly temperature was 2.3 degC above average and there were only 3 slight air frosts. Although there was a high number of days with rainfall the monthly total was only 97% of average, despite a very wet day on the 15th. It was also a very windy month after a calm first week, equal windiest month since installation of anemometer in 2004. Sunshine was a little below average with a long, gloomy mid month period.

• Wettest January day (15th) since recording began here in 1984
  
• Highest January monthly minimum of -0.1 °C beat -1.3 °C in 2005
  
• No falling snow or sleet observed during the month

* - Infuriatingly, it seems people at home are incapable of looking after... or more importantly leaving alone the weather tracking software, when I'm away, as I was from January 15th onwards. Consequently, during my absence, the following downtime (totalling around 105 hours) occured, which is likely to have influenced all statistics marked with an asterisk.

No Maximum temperature was available for days 17, 20, 22, 24.

No Minimum temperature was available for days 18, 20, 23, 24, 25, 26, 29.

No Rainfall data was available for days 17-18, except that 13.47mm fell over the course of the two days.

The 12th was calmer with sunny spells.

The following days were again very breezy with showers on the 13th, and heavy rain on the 14th. Showers on the 15th cleared only to be followed by a long spell of heavy rain and gales.

It became very mild by the 19th with a high of 12.4C - the highest temperature of the month. Heavy rain cleared in the afternoon.

Heavy rain once again battered us on the 21st and showers followed but generally lighter than the rain front. There were gales for a time but calmer weather followed with sunshine on the 22nd, murk on the 23rd, clear skies on the 24th anda generally dry end to the week bar a few showers on the 25th.

Due to a clear night and cloudy day on the 28th, the temperature only reached 5.7C on the 28th, but 11.8C in the sun on the 29th. The 30th was cold and sunny after overnight rain and the month ended with a weak weather front introduce colder air behind it on the 31st.

Apart from a short cold snap during the first week as high pressure built over Scandinavia, virtually the whole of January was dominated by areas of low pressure coming in off the Atlantic, these produced mostly very mild south or southwesterly winds giving unsettled and wet conditions.

The second mildest January on record, the month finished just 0.1°C below last year. The month was also the wettest on record, with more rainfall than would be expected during the entire winter quarter. It was also the first January to fail to record an air frost, with a minimum temperature of +0.3°C and only 4 days dropping below 3°C.

The month started off with a short easterly spell. There was a brief half-covering on the 3rd which melted by 11am. This turned out to be the only lying snow of the month (and winter so far). Despite the cold snap, the first half of the month was 1.5°C milder than average. It took until the 18th for a temperature of 10°C to be topped however. The remaining 13 days averaged 8.0C, with double figures reached on all but 4.
