Agricultural production is closely linked with weather conditions, as fluctuations in temperature, rainfall, wind patterns and humidity significantly influence crop productivity. Adverse weather events often lead to considerable crop losses, emphasizing the need for timely and accurate weather information. Weather Based Agro Advisory Services (WBAAS) play a pivotal role in bridging this gap by providing farmers with real-time and forecasted weather information, enabling them to adopt strategic measures to mitigate risks and optimize agricultural outputs. WBAAS offers customized guidance based on weather predictions, including optimal sowing times, irrigation scheduling, pest and disease management and post-harvest strategies. By receiving accurate and timely advisories on parameters such as temperature, relative humidity, wind speed and rainfall, farmers can make informed decisions, reducing the likelihood of crop failure and improving yield quality and quantity. These services not only aid in minimizing production losses but also enhance economic returns by promoting resource efficiency and sustainable farming practices. The integration of technological innovations into weather based agro advisory services further strengthens their impact, facilitating the dissemination of precise weather data through mobile applications, SMS alerts and other digital platforms. Studies have demonstrated the transformative potential of these services in improving farmers' adaptive capacity and resilience against climate variability. This review analyses studies on how farmers utilize technological innovations combined with weather-based information to enhance agricultural productivity. It examines the impact of weather based agro advisory services on agriculture and explores their broader role in achieving sustainable farming practices and addressing challenges posed by climate change.
