We have lately experienced a time that has in media been narrated being an unusually long cold period in Finland. Among other things, this ha caused concerns of sufficiency of electricity production, and spot prices of electricity have been at record levels. But, after all, has this period been unusual? Here are some figures from...

Weather Station Nagu measures weather conditions using two equipment: Davis Vantage Pro 2 and WeatherFlow Tempest. While most of the observations are recorded by Vantage Pro, Solar Radiation and UV Index come from Tempest. Due to very little sunshine during November, on November 30, 2023 at 3 pm, the Tempest’s solar powered battery was depleted,...

Following this morning’s lightning strikes, Station Master noted that Last Lightning time was displayed in UTC time instead of local time. This is now corrected.

Station Master checked all links on Links page, fixed not working ones and removed obsolete links.

Today there was a few hours update failure of Solar Radiation and UV Index. They were not updated between 10.30 and 15. Issue was with weewx on Raspberry Pi.

New Davis Vantage Pro 2 equipment has been operational since April 6, 2023. Especially rain and wind measurement are now more accurate. Regarding rain measurement, Tempest is not able to detect snowfall, and measurements were completely erratic during January-March this year. It turned out that main reason for this was bird repellent spike collar that...

Weather Station Nagu started summer 2003 when Station Master decided to combine weather observation and computer software related hobbies and create a local weather station publicly available on Internet. The original equipment was based on Davis Vantage Pro hardware. That equipment lasted over 15 years with quite a minimal maintenance, and parts of it are...
