December 2020 proved to be average in terms of temperature. The mean daily maximum temperature during the month was 9.6C, 0.2C lower than the long-term (1981-2010) average, and the mean minimum temperature was 4.6C, 0.2C above average. The highest air temperature measured during the month was 13.6C on the 21st. The lowest minimum air temperature was -0.7C on the 7th, and lowest grass minimum was -4.4C on the 7th and 8th, with 1 air frost and 15 ground frosts recorded during the month.
Following a slightly drier than average November, December was much wetter than average with 179mm of precipitation recorded in my accurate 5 inch copper rain gauge, 174% of the average. My less accurate automatic Davis gauge recorded 168.4mm during the month. The wettest day was the 18th with 27.2mm collected in my copper gauge. Rain or heavy dew amounting to 0.2mm or greater was measured on 27 days, 1mm or more on 15 days, and 10mm or more on 22. So just 4 dry days!
As for 2020 as a whole, the mean daily maximum temperature was 15.46C, 0.96C above the long term average, and mean daily minimum 8.94C, 0.74C above the long-term average. Overall 2020 was 0.21C warmer than 2019 and 0.85C above the long-term average, and was the warmest year since 2014. The past 10 years have all been above the long-term average. Highest temperature during the year was 29.7C on 8th August, not far off record of 30C. Lowest temperature was -1.4C on 21st January. Three air frosts were recorded in 2020 (2 in Jan and 1 in Dec), one less than 2019 and well below the long-term average of 14.4. There were 53 ground frosts (10 in Jan, 10 in Feb, 15 in Mar, 1 in Apr, 2 in Nov and 15 in Dec), one more than 2019 which itself was one more than 2018. There are no long-term statistics for grass frost in Teignmouth although my average for the period 2009-2020 is 66 grass frosts (and 11 air frosts for the same period). Total rainfall recorded by my manual gauge was 1076mm, 127% of the average, 20.2mm higher than 2019. 2020 was the wettest year since 2014 when 1131.4mm was recorded. Wettest day of the year was 15th February when 43.4mm were recorded. Rain or heavy dew amounting to 0.2mm or greater was measured on 217 days, 5 more than in 2019. During the period 2009-2020 the annual average was 200.

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.
