Manila Observatory served as observers and providers of information about the weather conditions in the Philippines during the latter part of the 19th century.

The Manila Observatory played a crucial role in the historical development of meteorology in the Philippines during the late 19th century. Established in 1865, it was one of the earliest scientific institutions in the country dedicated to the systematic study of meteorological phenomena. The observatory's primary mission was to collect weather data, which included temperature, humidity, rainfall, and atmospheric pressure.

During this period, it operated under the management of Jesuit priests who not only focused on studying the weather but also sought to improve agricultural practices by providing timely weather forecasts to farmers. Their work allowed for better preparation against extreme weather events such as typhoons and droughts, which were significant to the agricultural sector in the Philippines.

Furthermore, the data gathered by the Manila Observatory contributed immensely to the understanding of tropical weather systems, making it an important institute in the history of meteorology in Southeast Asia. The observatory's legacy continues today, as the data and insights from that era laid the groundwork for modern meteorological practices in the region. The observatory's contributions were not only instrumental in local weather monitoring but also in advancing global meteorological science through data sharing and international collaboration.
