During Nov 1-3, Solar Radiation and UV Index were not measured and this was not noticed by Station Master. Weatherflow hub had lost wifi connectivity. Probably the storm on last Friday causing several power failures and power surges was a reason to this. Rebooting Weatherflow hub solved issue this morning.

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.

Weather Station Nagu’s wind gauge has changed. Now the 10 minute average wind and gusts are shown in one gauge, gusts being in parentheses.

On Wednesday, July 19, 2023 WS Nagu witnessed a very local rainstorm. While writing this, it has been raining about an hour, with peak rate almost 100 mm/hour. Total rain will exceed 23 mm.

There was an outage that was due to a MicroSD card failure of one of the Weewx servers collecting and sending weather observation data to station’s web server. Actually, there has been three Raspberry Pi computers involved in the process, two running Weewx and one Home Assistant. While fixing this, Station Master decided to simplify...

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...
