A personal weather station is different from an official weather station because it is set up on personal property by regular individuals and weather enthusiasts. We recommend that personal weather station owners set up the device based on these weather station siting guidelines for the highest accuracy possible. However, that is not a requirement as it is for official weather station siting and setup. Additionally, a personal weather station often reports more frequently than an official weather station. AcuRite weather stations report as often as 18 seconds, while official weather stations report hourly. Get live weather updates with all AcuRite weather stations: Notos, Iris, or Atlas.
