MARCH 2006
|
||
| Note | A total hosepipe and sprinkler ban is in effect in South East Water & Mid Kent Water supply areas until further notice. |
| 1st - 6th | A cool but bright start to the month with long sunny periods. A low pressure system to the SW threatened wintry weather on the 3rd but passed well south and gave heavy snow to N France instead. |
| 7th - 10th | Becoming unsettled with a series of weather fronts bringing in maritime air, spells of rain and showers across the UK from the west. Winds turn to NW on the 10th. |
| 11th - 16th | Pressure rises to the NE, bringing winds from the N and another cool spell. Heavy snow fell in Scotland and northern England on the 11/12th, but conditions stayed mostly dry, bright and breezy here. Mixture of sunny days / anticyclonic gloom with chilly winds followed. The coldest first half of a March since 1987. |
| 17th - 23rd | Anticyclone to south of Iceland and low pressure in Biscay brings stronger NE'ly winds. Remaining dry and fresh with plenty of cloud. The pattern starts to change on the 23rd as an Atlantic low pushes towards the SW. |
| 24th - 31st | The surge of Tropical Maritime air pushes the temperature to its highest readings since last November. Becoming humid, very windy and mostly dull with frequent outbreaks of drizzle and rain. The 27th was the windiest day of 2006 so far. |

| † Sunshine Hours are approximate only and calculated from the sensor's limited exposure to direct sun, no allowance for visual only observation. As the sensor receives less than 55% of total possible sunshine exposure this month, the figures above can be very significantly less than the actual sunshine duration. * = deviation from 20 year average. The monthly mean is calculated from all logged temperatures and is not the simple mean of the daily minimum and maximum. THW = Shaded Heat Index calculated with cooling/warming effect of wind and humidity to give an apparent temperature. THSW = Unshaded Heat Index calculated with cooling/warming effect of wind, humidity and full direct sunshine to give an apparent temperature. EVAPO-TRANSPIRATION is drying effect due to sun and wind, and is equivalent to "negative rainfall" |

| ‡ SUN: Sunshine hours are calculated approximately and solely from solar radiation readings, but note that the solar sensor's exposure to sunshine is rather limited. The sensor receives only 45-55% of total possible sunshine exposure this month, and there is no allowance for sunshine by visual observation only, so the figures above can be very significantly less than the actual daily sunshine duration. |

'WIND ROSE' PLOT FOR THE MONTH |
|
 |
The 'petals' represent wind direction and the length represents frequency, i.e. in this case winds from the SSW were the most common, followed by the ESE then ENE and N. The colours represent the strength of the wind, with black being weakest through blue then lighter colours (cyan, light green, yellow, magenta, red) being stronger. This data excludes 'calm' readings. |
