The range of the entities cooperation within a specific area and the effectiveness of such cooperation depend among others on the local market awareness. Such cooperation may be supported by a systematic market monitoring by the local government. This opens up the opportunities for not only reasonable targeted cooperation but an effective management of the resources owned by particular local organisations, and development creation as well. The aim of this paper is to present the importance of tourist market monitoring in tourism development on the local scale and the manner it is built, taking the city of Gdynia as an example. This article is based on the respective literature study and research, including surveys spread among travel agencies for inbound tourists located in the city of Gdynia. For the surveyed entities the knowledge about the tourist market is of great importance and the urge to mutually cooperate and have access to the current information big enough to have the local government of the city of Gdynia implement a special “Tourist Market Monitoring Programme”.
