The Weather, in Royston

Record temperature for Royston

40.2C at 14:41 Tuesday July 19th

Another new record high temperature for Royston.

The July 2019 record of 39.0C beaten at 17:49 on July 18th 2022 the highest temperature measured in Royston was 39.2C.
It was a hot night following the record breaking day with the temperature not dropping below 23.6C - another record.

News Page gets a makeover

Welcome to the new look News page

The Sun Hill weather site is now over twelve years old and the Development Officer thought it time to update the look of the site, starting with News page.

A wider space is available for the posts along with easier navigation between posts. It is also allegedly much easier to use than the old code-it-in-HTML system and it may well be when I can fathom how to use it.

Rain is back after 25 days

On May 4th there was 7.8 mm of rain after 25 dry days. This is almost as much as fell in the whole of April - 9.9 mm

By the end of April 2022 Royston was down by 50 mm compared with an average year’s rainfall total for January to April, a whole month’s rain.

Yet another mystery downpour explained

A mystery downpour for 21 October 2021 is really delayed rain from 20 October 2021.
Removing rubbish from the rain collector released a rush of rainwater.
So 20th and 21st should read 23.4 and 3.4 mm (not 11.4 and 15.4).
The weather station has been given a good wash and brush-up.

June 21 dryish and warmish

Despite the cold and wet of the last week the month, as a whole June was above
the recent average for temperature at 17.1C and below average rainfall despite
one day of downpour. The rainfall was 32.2 mm, about two-thirds of an average
June.

Raspberry Pi goes to bed

More power outages

The latest power outage which brought down the Raspberry Pi on June 18th 2021 has again had the electrician scratching his head - see entry below for November 2015 - so again I have had to move the Pi and weather station console to a bedroom on a different ring main. A shame as the console is a quick source of the current weather status when it is in the study downstairs.

April 2021 Review

Cold and Dry

There was virtually no rain in April, the third month in a row of low rain as the graph below shows.
According to the Met Office April 2021 had the lowest average minimum temperatures for April in the UK since 1922. April in Royston was not quite the coldest but getting there and certainly the coldest I have recorded.

How cold has it been this February?

February Review?

The lowest temperature this month was -4.2C. Feb 2018 was -6.2C and Feb 2012 was -10.9C (the lowest temperature I have recorded). What has made it feel especially cold in 2021 is that we had 6 days consecutively with and average below zero whereas 2012 only had 3 days in total. 2012 was the record with 10 days averaging below zero. The History Page will show you all of the averages.

Outage Again

There was an outage for a day when an upgrade failed. A complete rebuild of the system was needed. We have a daily backup so no data was lost and it was simple to re-instate the control files.
