The objective of the paper is to document and examine the majorupwelling event that occurred along the northern coast of Estoniain August 2006. With a horizontal extension of 360 km, the eventwas caused by persistent easterlies and was noticed by a largenumber of holidaymakers, as it turned the temperature of thecoastal sea to a chilly 5-10°C for about a month. Insitu measurements from an RDCP current profiler revealed an along-windcoastal jet of up to 60 cm s^-1 and a weak near-bottom countercurrent.The depths of the pycnocline and nutricline rose. The maximumdrop in water temperature was 16°C, that of salinitywas 3.6 PSU. Analysis of satellite images confirmed the largeextension and the prominence of the event.
