.... February sunshine at Hurn (Kipp & Zonen sensor/KZS) was ~43 hours
(provisional), roughly 58% of the 1971-2000 LTA or ~1.5hr/day. In 1969+ Hurn record only beaten for lack of sunshine (allowing for change of instrument) by 1972 & 1976 (latter the lowest .. at least the summer made up for it). Of more significance, aggregating the sunshine total for the months November 2010 - February 2011 (rough CSR equivalent = 195 hr) then it looks as if we've had the *dullest* such 4-month period in the Hurn record; previous lowest was 1994/95 with 209 hour (CSR). The 195 hour total over those four months represents around 70% of the LTA 1971-2000. Martin. -- Martin Rowley West Moors, East Dorset (UK): 17m (56ft) amsl Lat: 50.82N Long: 01.88W NGR: SU 082 023 |

Even had a brief snow shower on Holmbury hill, Surrey this afternoon. Felt like early January again this afternoon with the leaden skies making it seem almost dark at half past four. |

Dave Certainly perceived as a very gloomy month here in Southampton (along with January, December [redeemed by snow] and most of the second half of 2010, except October). And not just the lack of sunshine but the number of days with 8 oktas of cloud and low stratus, which seemed pretty exceptional - even a 5 or 6 okta day was seen as something of a luxury during February. Typically, the perceived time of it "getting dark" was around 15 minutes before sunset, when in more average conditions it's normally around sunset or even slightly later. So effectively we seem to be running a couple of weeks "behind schedule". Jan and Feb combined really have seemed very, very gloomy round here. Especially annoyingly, the weather type has not been constant: there's been a mixture of tropical maritime, gloomy highs, and an unfortunate deadlock between Atlantic and continental air which seemed to be stuck over the area for most of the second half of Feb. By contrast, the "sunnier" types, whether they be arctic northerlies, polar maritime (very noticeable by its absence) and sunny highs, have barely got a look in. March has started on the same old theme, the "deadlock" block being replaced by our old friend the gloomy high. The sun is allegedly still up as I type this, yet it seems like around 20 minutes after sunset. Hope something changes soon... so far this has been the least inspiring start to a calendar year I can remember. Nick |

: Of more significance, aggregating the sunshine total for the months : November 2010 - February 2011 (rough CSR equivalent = 195 hr) then it : looks as if we've had the *dullest* such 4-month period in the Hurn : record; previous lowest was 1994/95 with 209 hour (CSR). Compared with Brussels you have been quite favoured. November to February inclusive sunshine at Brussels Uccle - 163 hours 56 minutes 3 winter months - 140 hours 10 minutes November - a dismal 23 hours 46 mlinutes ! Colin Youngs Brussels |

Nick The cloudiness during February is probably why there has been a distinct lack of air frosts as well. In fact, I can't remember the last time I awoke to a frosty landscape. |
