July 2022 was 1.3C warmer than average overall, the 6th month in a row with above average temperatures. The mean daily maximum temperature was 23.0C, 1.9C warmer than the long-term (1991-2020) average, and mean minimum temperature was 14.5C, 0.8C above average. The highest air temperature measured during the month was 29.3C the 19th, just short of the highest July temperature (29.6C on 8th July 2018) since my observations began in May 2008 and that is still below my record temperature of 31.8C recorded this year on 19th June. The lowest minimum air temperature during July 2022 was 10.1C on the 1st, and lowest grass minimum was 6.7C on the 28th. The mildest night was the 19th when the temperature didn't drop below 21.4C, the highest minimum I've ever recorded. No air frosts or ground frosts were recorded. So far during 2022 two air frosts and 38 ground frosts have been recorded.

July 2022 was much drier than average with just 2.5mm recorded in my accurate 5 inch copper rain gauge, 5% of the long-term (1991-2020) average. This was the driest July I've ever recorded and if data from sites within 1km of Teignmouth Den are considered, is joint driest with 1935 in a series that I've extended back to 1854! My less accurate automatic Davis gauge recorded 2.8mm. The wettest day was the 1st when 1.4mm was collected in my copper gauge. Rain or heavy dew amounting to 0.2mm or greater was measured on 4 days and 1mm or more on just 1 day. Just for the record, only March this year had above average rainfall and so far this year I've recorded just 266.7mm of rain, that's just 59% of the long-term average.

As for 2021 as a whole, the mean daily maximum temperature was 15.24C, 0.24C above the long term 1991-2020 average, and mean daily minimum 8.78C, 0.38C above the long-term average. Overall 2021 was 0.19C cooler than 2020 but 2021 was still 0.31C above the long-term average, and was the second warmest year since 2014. Highest temperature during the year was 26.8C on 21st July. Lowest temperature was -2.1C on 1st January. Thirteen air frosts were recorded in 2021 (8 in Jan, 1 in Feb, 3 in Mar and 1 in Nov), the highest total since 2012 when 15 were recorded, and above the long-term average of 11.1. There were 70 ground frosts (18 in Jan, 12 in Feb, 12 in Mar, 15 in Apr, 2 in May, 3 in Nov and 8 in Dec), 17 more than 2020. There are no long-term statistics for grass frost in Teignmouth although my average for the period 2009-2021 is 66 grass frosts (and 11 air frosts for the same period). Total rainfall recorded by my manual gauge was 1000.5mm, 115% of the long-term 1991-2020 average, 75.5 lower than 2020 which itself was the wettest year since 2014 when 1131.4mm was recorded. Wettest day of the year was 12th May when 56.2mm was recorded. Rain or heavy dew amounting to 0.2mm or greater was measured on 186 days, 31 fewer days than in 2020. During the period 2009-2021 the annual average was 199.

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.
