On April 4 after 11:30 pm Tempest’s relative humidity sensor failed and started showing steadily 7%. After reporting this to WeatherFlow support, defect was verified and a replacement unit is on the way. Until the new unit arrives, relative humidity is measured using Ruuvitag. Also solar power measurement is likely faulty showing too high values....

Water Height Cam Removed
Since it is not probable that Käldö water height cam comes online, Station Master removed it from station’s menu.
Freezing Finnish Independence Day
This day, December 6, is Finland’s Independence Day. Today, outside temperature was -13,8 °C at 8 am. It is a record low measure during weather station’s history, as the chart shows: Also the chart showing daily temperatures show that we are experiencing coldness not at all normal:
The Heat Is On!
The rain collector heater at least is on. On these latitudes, the nature’s heat is not anymore on, so it may be snowing any day now..
Failed Rain Measurement
Long awaited rain came lat night, but WS Nagu did not report rain at all. Today, Station Master inspected Davis rain gauge (which is still used to report rain instead of Tempest), and the reason is now clear: the gauge’s funnel was completely clogged with pollen and other stuff. Station Master should have cleaned the...
Tempest and Rain Measurement
WS Nagu’s current equipment, WeatherFlow Tempest is installed on top of a mast on Station Master’s house’s rooftop. This should be an ideal placement to measure wind. But a downsize has been that the haptic rain sensor has not worked reliably, due to vibrations of the mast. So far, rain measurement has been taken from...
Tempest Lightning Detector
WeatherFlow Tempest has a lightning detector. Since station arrived, Station Master has not been able to check whether the detector actually works. But today, there was a thunderstorm in Turku at the time Station master was there, too. Quick check showed that the lightnings were detected in Nauvo. Some settings regarding lightning reporting were off,...
NSS Webcam Back Online!
Nagu Yacht Club’s webcam is back online. Hooray! https://rosti.fi/saa/nssn-kamera/?lang=en
Summer Has Begun
It certainly looks summer began two weeks earlier than last year. Forecasts suggest mean temperatures stay above 10 °C at least in the near future.
Weatherflow Tempest Issues
Weather Station Nagu currently relies on three different set of sensors: Weatherflow Tempest, Davis Vantage Pro and Ruuvitag. A while ago, Tempest’s humidity and rain sensors stopped working, but luckily this did not cause any issues, because those measurements shown on WS page are not from Tempest. However, faulty Tempest will be replaced with a...
