kesävuorovesiin

Kesävuorovesiin refers to the phenomenon of increased water levels in coastal areas during the summer months, particularly in the Baltic Sea. This rise in water level is primarily caused by a combination of meteorological factors. Strong and persistent southerly or southwesterly winds blowing across the sea can push water towards the coast, leading to elevated sea levels. This effect is often exacerbated by low atmospheric pressure, which can also contribute to a higher sea surface.

While often referred to as "summer tides," it's important to note that kesävuorovesiin is not a true tidal phenomenon driven by lunar or solar gravity. Instead, it is a weather-dependent event. The duration and intensity of these high water periods can vary significantly from year to year and depend on the prevailing weather patterns. Coastal communities, especially those in low-lying areas, monitor these events as they can potentially lead to minor flooding, increased erosion, and impacts on navigation. Traditional knowledge often associates these summer high waters with specific wind directions and atmospheric conditions.
