January 2015 Stats

Postby Eddy Graham » 2015 Feb 03, 22:11

Hi everyone

I see some folk have already posted a mix of a January data, so I thought I'd try to start a regular monthly item tonight - soon after the end of each month (and before the COL bulletin is ready), I'll try to post my Stornoway Town stats for the previous month and maybe a photo or two as well. As I'm sure you'll all appreciate the weather is often VERY different here to the rest of the UK!

So here goes for January 2015.

Mean max: 6.5C
Highest Max: 10.6C on 9th and 25th
Lowest Max: 1.5C on 13th
Mean min: 1.3C
Highest Min: 6.9C on 1st
Lowest Min: -2.2C on 20th
Mean: 4.2C
Difference of mean from average: -0.2C (1873-2010 mean, Stornoway town area), -0.7C (Stornoway Airport 03026, 1981-2010 mean. N.B. 03026 is yards from the sea, so often quite different from town)

Precip Total: 250.7mm (192% of the long-term Stornoway area 1873-2010 mean, 167% of the Stornoway Airport 1981-2010 mean- the latter is usually a much 'drier' site by 20-25% compared to sites near the town)
Wettest day: 29.6mm on 8th (i.e. to 09h00 on the 9th)

Lowest grass: -6.7 on 20th
Thunder 3
Hail 20
Snow Fall 19
Snow Lying 10 (greatest since Dec 2010)
Grass Frosts x
Air Frosts 4
Raindays 29
Wetdays 25

So overall: A another remarkable month in Stornoway, notwithstanding the hurricane of the 9th. It was exceptionally wet (2nd wettest month I have recorded here since arriving in 2009), and the number of snow lying days (10) was greatest since Dec 2010. Three (3) days of thunder was also noteworthy.

This month's photo actually comes from yesterday (2nd Feb), taken at lunch-time on the Stornoway Golf course, looking east towards the Scottish mainland (on a clear day, the peaks of Suilven and NW Highlands can be seen; Obviously, the trees shown didn't get blown over in the hurricane! - though many were...).

I won't add the longer comment fields here, as these have mostly been expressed in previous posts - but in future I might do so (if not too verbose). Please feel free to reply to this and post your own data (if you haven't already done so) - thanks

Here's the January figures for Farnborough, with comparisons from the estimated LTA (based on the Met Office climatological figures for Farnborough)

Mean Max: 8.3 (+0.6)
Mean Min: 0.9 (-0.4)
Mean: 4.6 (+0.1)

High Max: 14.5 on the 9th
High Min: 8.7 on the 9th

Rain Total (gauge): 52.3mm (77%)*

Days with:

Snow lying 1
Thunder 1
Fog 1
Small hail 1
Large hail 0

Temperature wise, it was a month of two halves that averaged out to very close to normal.

* Note that my gauge tends to under-read due the proximity of the house (further from the house would be under tree branches, so I'm stuck!)
