Welcome to the Windrush Weather Station in Marlborough

Marlborough High Street in Summer

Marlborough is a rural town with a population of approximately 7500 people. My weather station site is on the eastern edge of the town some 150 metres above sea level where I have been making accurate weather observations since 1984. Below are the data and graphs for the Actual Temperatures, Mean Temperatures and Rainfall for each month along with details of the annual statistics and record-breaking data. Readings are taken daily at 0900. Data Since 1984: Every Month of the Year Seasonal Data: Spring: Temperature, Rainfall Summer: Temperature, Rainfall Autumn: Temperature, Rainfall Winter: Temperature, Rainfall Annual Data: Mean Temperatures Rainfall Wind Direction Highest and Lowest: Record Data Monthly Records

Current statistics: June 2009 Updated 29/06/09 Last month: May 2009 The month was noticeable for the relatively high average air pressure with the minimum not falling below 1000.0 Mb. This resulted in 17 totally dry days and when rain fell the daily totals were not large – 8.0mm on the 14^th being the wettest day. With the rainfall for the month totaling just 31.7mm, being 52% of the long-term average, it was the driest May since 1998. Most of the shower activity centered around the 14^th – 19^th due to low pressure to the west of the country. As pressure rose again from an Azores high, temperatures picked up and brought glorious hot, sunny weather to conclude the month although maxima were trimmed due to brisk easterly winds. There were two nights with minimal air frosts on the 4^th and 10^th. May 2009 produced the 14^th consecutive month with above average temperatures (+0.7°C) with the hottest day being the 29^th when the thermometer peaked at 24.6°C. The winds on the 11^th and 12^th were notable. Although the maximum gusts were 38mph and 36mph respectively, which are not unusual, strong winds were maintained throughout each 24 hour period. The average for each day was 12.5mph and 11.8mph, which is very high, and only exceeded on 14 mostly winter days in the last 10 years. Daily statistics: May 2009

My weather station consists of the standard 5 inch copper rain gauge and a maximum/minimum thermometer inside the Stevenson Screen. In addition I have a Davis Automatic Weather Station that continuously records more detailed temperature data from inside the screen and wind speed with wind direction from the instruments high above roof height. It monitors the sensors every 15 seconds then records the highs and lows every half hour. This data is then downloaded onto my computer for further analysis and graphing. Eric Gilbert
