The weather station at east Durrow was set up in May 2008. The equipment used is a Davis Vantage Pro II that measures temperature, humidity, wind speed, wind direction, rainfall and barometric pressure. This data is transmitted every 2 seconds to the internet website http://www.laoisweather.com where the data can be freely accessed. The station also reports to the Irish Weather Network which displays live weather data from similar stations all around Ireland.
In addition, a Met Eireann climatological station (Number: 472) was installed in September 2010 and the data collected is sent to headquarters in Glasnevin, Dublin on a monthly basis. The climatoligical station measures rainfall in a manual gauge, soil temperatures at 5cm, 10cm and 20cm depths, air temperature including wet-bulb, daily maximum and daily minimum temperatures. The climatoligical station is a project that is envisaged to last thirty years and collect a climate profile for Durrow.
The weather of Durrow can be best described as temperate with rare extremes when compared to other locations around the world. However, when looking at the data and comparing it to other locations in Ireland it is notable that Durrow is amongst the warmest locations in Ireland during the summer, and conversely the coldest in winter. Owing to it’s proximity to the “sunny southeast” the town receives lower rainfall than the national average.
The following table gives the expected mean temperatures, rainfall and sunshine for each month of the year…

Snowfall varies greatly from year to year, but averages out around 20 days per year. Snowcover is rather rare, usually averaging less than ten days per annum, occurring mostly in late winter and early spring. Some winters can have no snow-cover, but again these are rare.
Thunderstorms are also very infrequent and when they do occur they are mostly weak storms. On average there is less than ten days per annum where thunder is observed. Thunder is most likely in late spring and summer months, but can occur during any month.
Fog is observed on average 40 to 50 times a year with the autumn and winter months featuring most fog. Hill fog is usually associated within warm sectors of a low pressure system containing a southwesterly airflow.
Air frost occurs on average slightly more than 50 nights of the year, with air frost during summer months almost unheard of. Grass frost occurs on over 100 nights of the year with the summer months by-and-large escaping these.
Durrow lies in the Nore valley and the surrounding terrain greatly influences the wind speed the town experiences. Gales are quite uncommon, occurring on less than five days per year with the winter months most likely to feature gales. The average wind speed is 6.5mph (10.5kph) on any given day. The prevailing wind is southwesterly.
Rainfall, as the tables above suggest is plentiful, however it is important to note that nearly 200 days per year will record little or no rainfall. (less than 0.2mm/0.1in)
Since May 2008 the following temperature records were established at Durrow: Max: 27.7c (81.2F) on June 2nd 2009; Min: -14.0c (+6.8F) on December 25th 2010.
