Key Benefits

Current Conditions
Current weather conditions are shown for the named locations based on the nearest weather stations. Vaisala gathers the observation data only from the official SYNOP and METAR weather stations to ensure high-quality data. The file is updated at least every 15 minutes, but the update frequency of any given observation station's data depends on the transmitting frequency of the station, which typically varies between 10 minutes and 3 hours; there are also some manual stations that do not measure during the night. When we choose which stations to use, we try to ensure that the weather conditions are as close as possible to the ones at the location they represent. Optionally, the feed provides also the observations from the past day for selected stations and parameters.
