We explored a coastal site on Käsmu peninsula in the Gulf of Finland in Northern Estonia. We were interested in the changes in the microclimate with location and time at the coastal site. How the temperature and humidity change over time and in different locations. We had five different sites, starting from the shore to the forest, the distance between sites only 50 metres. And our hypotheses were: ● The temperature will increase a little and will start decreasing as the sun is setting. ● The humidity will change only by a few percent, so it will stay even. ● The temperature will decrease as we are moving away from the shore and more inland. ● The humidity will also decrease as we are moving away from the water. ● The tree height will increase the further we go from the shore. Out of the five hypotheses three were fully supported and two were partly supported. The biggest surprise was in how much the temperature changed and how uneven it was. One of the reasons for the mismatch could be because we did not consider how the coast is colder in the summer than the inland, as is typical for areas with maritime climate. In the future the research should be more thorough, we should bring more tools and the methods to take measurements should be more clean and done more precisely. And it would be interesting to take measurements over a longer period of time.
