August 2020 proved to be the 9th month in a row warmer than average with a mean daily maximum temperature of 21.9C, 1.2C higher than the long-term (1981-2010) average. The mean minimum temperature was 15.3C, 1.6C higher than the average. The highest air temperature measured during the month was 29.7C on the 8th, the highest of 2020 so far and the hottest day since my records began in 2008 but below the all-time Teignmouth record of 30.0C on 29th June 1976 on the Den and during July 1881 at Woodway House. The previous record at my site was 29.6C recorded on the 8th July 2018. The lowest minimum air temperature was 10.1C on the 31st, and lowest grass minimum was 7.2C on the 4th. No ground or air frosts were recorded. So far during 2020 some 36 ground frosts and 2 air frosts have been logged.

August was considerably wetter than average with 134.8mm of precipitation recorded in my accurate 5 inch copper rain gauge, 249% of the average, the wettest August since 2015 when 156.0mm was recorded. My less accurate automatic Davis gauge recorded 147.0mm during the month. The wettest day was the 27th with 33.7mm collected in my copper gauge. Rain or heavy dew amounting to 0.2mm or greater was measured on 24 days, 1mm or more on 9 days, and 10mm or more on 4.

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.
