This article examines the development of a storm warning system along the Finnish coast between the 1860s and the 1920s, situating it within broader transformations in maritime trade, shipping technology, and coastal societies in the northern Baltic and Scandinavia. It argues that the sixty-year delay in the implementation of a comprehensive storm warning system was not primarily due to the unreliability of the warnings themselves, but rather to a misalignment between the system and the priorities of maritime commerce, as well as the maritime safety strategies of Finnish authorities. Contrary to its original nineteenth-century conception as a safeguard for sailors, the storm warning system was ultimately introduced in the 1920s Finland as a low-cost technological fix to the economic struggles of fishing communities. The article further contends that to better understand weather-society relations, historians must critically examine the institutional and social dimensions of weather services. Rather than merely tracing how services such as storm warnings were developed, it is essential to ask why they were created, for whom they were intended, and what roles they played in shaping society’s relationship with the weather.
