January 2020 proved to be milder than average with a mean daily maximum temperature of 10.0C, 0.6C warmer than the long-term (1981-2010) average. The mean minimum temperature was 5.2C, 1.2C above average. The highest air temperature measured during the month was 14.3C on the 30th. The lowest minimum air temperature was -1.4C on the 20th, and lowest grass minimum was -5.0C on the 20th. Ten ground frosts and 2 air frosts were recorded.

January was wetter than average with 105.5mm of rain recorded in my accurate 5 inch copper rain gauge, 111% of the average. My less accurate automatic Davis gauge recorded 127.2mm. The wettest day was the 14th with 16.3mm collected in my copper gauge. Rain or heavy dew amounting to 0.2mm or greater was measured on 25 days, 1mm or more on 15 days, and 10mm or more on 4.

January saw an unusually intense anticyclone reside over the southern UK with central pressure exceeding 1050hPa for the first time in over 90 years. Dunkeswell in East Devon reported the highest hourly observation of pressure during this event of 1050.4hPa at 2am on 20th January. My highest hourly value was 1050.2hPa at both midnight and 2am. I archive conditions every 10 minutes, and my highest 10 minute value was 1050.3hPa at 0:10am and 0:50am. I also log the instantaneous highest pressure. 1050.4hPa was briefly achieved at several points overnight on 19th/20th. This is still some way off the UK record of 1053.6hPa in Aberdeen on 31st January 1902.

As for 2019 as a whole, the mean daily maximum temperature was 15.2C, 0.7C above the long term average, and mean daily minimum 8.7C, 0.5C above the long-term average. Overall 2019 was 0.2C cooler than 2018 but still 0.6C above the long-term average. Four air frosts were recorded in 2019 (2 in Jan, 1 in Feb and 1 in Dec), well below the long-term average of 14.4, and 6 less than 2018. There were 52 ground frosts (17 in Jan, 15 in Feb, 7 in Mar, 1 in Apr, 1 in Nov and 11 in Dec), one more than 2018. Total rainfall recorded by my manual gauge was 1055.8mm, 125% of the average. The total was 40mm higher than 2018 and it was the wettest year since 2014. Rain or heavy dew amounting to 0.2mm or greater was measured on 212 days, 30 more than in 2018.

The tables above show weather conditions recorded by a Davis Vantage Pro 2 automatic weather station sited in Teignmouth, South Devon. They are usually updated every 10 minutes. All times are Greenwich Mean Time (GMT), so add one hour for British Summer Time (BST).

* Air temperature is measured 1.9m above ground level and the anemometer is just 2.2m above ground level in a NNW/SSE oriented valley. The wind direction is therefore heavily biased towards either the up or down valley direction and the anemometer is very sheltered from the prevailing westerly flow by higher ground directly upstream. The thermistor that measures grass tip temperature only has a resolution of 1 degree Fahrenheit and this has been automatically converted into Celcius to the nearest 0.1 degrees. A grass temperature of < 0°C indicates the occurrence of a ground frost (air temperature < 0°C indicates an air frost). The leaf wetness sensor monitors the level of surface moisture on foliage and hence the occurrence of dew, fog, drizzle, rain etc. Soil moisture is measured in centibars (cb) [0-10cb = saturated soil, 10-30cb = ground adequately wet, 30-100cb = ground needs irrigating to maintain maximum production, 100-200 cb = ground dry. ]. The strength of the sun's ultraviolet radiation is expressed as a UV index and was developed by the World Health Organization. As a guide 0-2 = low, 3-5 = medium, 6-7 = high, 8-10 = very high, 11+ = extreme. You can safely stay outside if UV is low, and it is recommended that you wear sunscreen if levels are moderate or higher, and seek shade if levels are high or above. In Teignmouth UV levels reach 7 in mid-summer and may reach 8 on exceptional days.
