The title analyses fluctuations and changes of some hydrometeorology parameters of Latvian coastal area in relation with the global warming, covering the time period of last centuries: water temperature changes in Bay of Riga, air temperature changes in the City of Riga, as well as the alterations of the water level in Venstpils and Daugava river basin. The findings reveal, that last centuries dynamic of the air temperature fluctuations is being expressed as the cyclic process, however, there is not considerable temperature growth monitored. The average tempo of water level growth in the area is considerably less than as compared with the records from last Glacial Era’s final phase. The global warming process is being continuing after the end of last Glacial Era up to now, and there is no solid ground for assumption, that this process has been facilitated nowadays
