This is due to the influence of cold fronts and cyclonic systems originating from the Atlantic Ocean. The low cloud ceiling and frequent precipitation result in reduced visibility and shorter daylight hours.

As spring approaches (March to May), the cloud cover gradually decreases, averaging around 50-60%. This shift is primarily driven by the northward movement of the sun and the increasing intensity of solar radiation. The skies become partly cloudy, with intermittent periods of sunshine and occasional showers. By the end of spring, the cloud cover typically drops to 40-50%.

Seasonal Variations in Cloud Types

The types of clouds observed in Gebze vary based on the season.
