The eclipse of 29th March 2006 was the last total eclipse in two nearest decades which was easy to be observed by europeans. The path of totality crossed Turkey, where main meteorological elements were measured. Those were: air temperature at 150 cm, relative humidity at 150 cm and global solar radiation. Also observations of cloudiness and wind speed were made. The weather conditions during the eclipse were very good. The solar eclipse caused in the observing site (Side) a dramatic change in illumination and amount of reaching radiation. In period of 77 minutes global solar radiation dropped from nearly 1000 W/m2 to 0. As a result of it temperature drop was 4.3°C (Tmax1 = 22.1°C; Tmin = 17.8°C). After the maximum phase the temperature rised at 4.5°C (Tmax2 = 22.3°C). The minimum of air temperature occurred with a dozen minutes delay, a similar shift was observed on 3rd October 2005 during annular solar eclipse in Spain. A radiation drop also caused a change in relative humidity, which reached maximum (62.1%) when temperature touched the lowest measured value. Daily amplitude of relative humidity was 27.5%. Local variations of air pressure could be a cause of gradual rise of wind speed and also its drop during a total phase of eclipse. Change of wind direction may be explained by influence of Moon’s shadow but also as an effect of regular breeze circulation. Cloudiness begun to increase just after the beginning of the first partial phase and soon before the end of the second partial phase it became stable at level of 3/8. High level clouds dominated.
