Population growth on the planet, including in Russia, causes a number of negative consequences. First of all, this is due to the irrational use of natural resources. Irrational deforestation, intensification of production, including the construction of environmentally harmful industries, which are often built in violation of the maximum permissible concentrations of pollutant emissions into the atmosphere. All this leads to irreversible consequences, such as: global warming, melting of glaciers, reduction of fresh water reserves, reduction of biodiversity up to the extinction of entire species and economic crisis. One of the main negative consequences, in our opinion, is global warming, which leads to planetary climate change. Therefore, in our studies, we studied the impact of climate change on the coastal tourism of the Black Sea coast of Russia by assessing several hydrometeorological factors – interannual fluctuations in surface air temperature and surface temperature of the Black Sea. The work used specialized data obtained using the MERRA-2 M2IMNXASM / M2TMNXOCN V5.12.4 models for the region covering the coastal zone of Russia from the Kerch Strait to the border with Abkhazia, for the period from 1981 to 2020. The analysis (Giovanni v.4.32) and visualization (Highcharts) of the data was made. A trend towards an increase in the average monthly values ​​of surface air and sea temperatures in the Black Sea region for the summer period (June–August), as well as for May and September, is revealed, which follows that the tourist season is gradually expanding mainly to September. The main thesis about the factors that should be taken into account when planning the development of coastal tourism, including investment and construction of infrastructure related to tourism on the Black Sea coast of Russia, is confirmed.
