Purpose. Determination of size, variability and gradient of cloudiness on the Polish coast of the Baltic sea during the summer half-year and identification of zones with variable suitability for recreation due to cloudiness. Method. The research is based on daily values of cloudiness in the warm half-year (April-September) recorded on a scale from 0 to 8 octants, obtained from six meteorological stations located on the Polish coast of the Baltic sea during the period 2000–2016. Methods of linear regression were used in the analysis of temporal variations of cumulative monthly deviations in cloudiness for consecutive years from the mean multiannual value. In terms of recreational suitability, days were categorised into four classes according to cloudiness. Three zones of varying conditions for recreation were identified. Results. The essential characteristic of cloudiness on the Polish coast of the Baltic sea is very high variability from one day to another and the resulting change in the value of solar radiation, which, consequently affects bioclimatic stimuli. Cumulative deviations of monthly cloudiness values from the mean multiannual value show a decrease in cloudiness in April, June and July, and an increase in the remaining months of the warm half-year. It is possible to distinguish three periods regarding increased frequency of clear and moderately clear weather lasting continuously for at least 3 and 5 days on the coastal zone in summer. The Polish coast of the Baltic sea is marked by three zones of varying conditions for recreation due to cloudiness in the summer – moderately favourable, favourable and very favourable. Research and conclusion limitations. Lack of access to time-specific results of cloudiness measurement. Practical implications. The results obtained in the course of this research may be used by individuals as well as the organizers of their stays, and for the purpose of characterisation of bioclimatic conditions of the coast. Originality. In view of the recent climatic changes recorded over the last 30 years, the present research demonstrates the current cloudiness level on the Polish coast of the Baltic sea. Type of research. Presentation of the results of empirical research.

Petroleum hydrocarbons (PHCs) are toxic for the water organisms and in sediments they may last for a very long time. The Baltic Sea is an area exposed to the PHCs due to highly developed shipping. In Poland, there is a lack of legal standards specifying guidelines regarding handling dredged material containing PHCs, excavated in waterways, roadsteads, and in port basins, and there are no standards specifying their acceptable concentration in sediments. Therephore petroleum hydrocarbons in the excavated dredged material are rarely examined at the Polish coasts. In years 2009-2018 only 4% of sediments were examined in terms of their content. Indicated that only the sediments from the open sea did not contain PHCs, the other ones were very or moderately contaminated with PHCs. Collected results clearly indicate that sediment should be monitored in terms of the PHC content, in most cases should not be thrown back to the sea. In most cases they may be stored onshore, but only on wastelands, mainly industrial and transport areas. Some of them may also be used in the areas of cleaner lands, i.e. forests, wood- and bush-covered lands, recreation and leisure areas.

This report focuses on the studies o f the bathing water microbiological quality in Latvian coastal zone of the Baltic sea and the Gulf of Riga in May-October, 1998-1999. The microbiological studies has been done in the different coastal zones of Kurzeme and Vidzeme, downstreams o f small rivers and biggest rivers Venta and Gauja, discharges o f wastewater treatment plants and the public bathing waters in Ventspils and Saulkrasti municipality area to assess their quality according to the EU Blue Flag and Latvian National Standard criteria. The microbiological examinations were carried out in accordance with the International Standard Methods. A complex of indicatororganisms - total and thermotholerant coliforms (E.coli), streptococci, and heterotrophicplate count (37°,21°C) has been tested. Water quality in the Kurzeme has been found much better on the beaches of the Baltic sea than the most urbanised beaches of Gulf o f Riga. The quality o f the Ventspils public bathing waters has been evaluated as very good (80-100% o f data). Whereas as a result of anthropogenic load only 61-82% o f data conforms the obligatory requirements of the bathing water quality in Saulkrasti coastal zone. In the study the microbiological pollution, sources and levels of their dynamics and hydrological factors are interpreted. The colour maps o f the bathing waters quality are presented.
