This work presents a proposal to determine the relative scale of ‘light pollution. The method is based on a simple analysis of data concerning the level of night lighting measured by a calibrated luxmeter. Such a relative scale can be also used in media for a so-called weather forecast. On the basis of the prognosticated cloudiness and rainfall it enables one to predict how dark the following nights will be. The study is an introduction to a deeper analysis which will be made after a longer period of measuring and getting data from another measuring site located in different environments (this site has been working just for a few months).
