A weather station is a site equipped with instruments that measure atmospheric conditions. Standard measurements include temperature, humidity, pressure, wind speed and direction, precipitation, and often sunshine or solar radiation.

Stations range from simple automated sites with a few sensors to fully staffed observatories. Instruments are carefully sited and calibrated to ensure consistent, comparable data. Many stations transmit observations automatically every few minutes; others report on a fixed schedule.

The global network of weather stations forms the foundation of surface observational data. The measurements feed models, climate records, and local forecasts. Specialized stations serve aviation, agriculture, or research needs with additional instruments.
