Höyryprü

Höyryprü is a term of Finnish origin that describes a very light, almost imperceptible rain. It is characterized by tiny water droplets that fall slowly and can feel more like a mist or fog than traditional rain. This type of precipitation is often associated with cool, humid conditions.

The word "höyryprü" is a compound word. "Höyry" translates to steam or vapor, and "prü" can mean drizzle or shower. Together, they evoke the image of a gentle, vapor-like descent of water. It is distinct from a downpour or even a steady rain, as the intensity is significantly lower.

Höyryprü can occur in various weather scenarios. It is often observed when warm, moist air cools rapidly, leading to condensation. While it does not typically accumulate significantly, it can contribute to dampness on surfaces and in the air. Visibility can sometimes be reduced during periods of höyryprü, similar to fog, though usually to a lesser extent. The sensation is one of being in a very fine, widespread mist rather than being directly hit by raindrops. Its gentle nature makes it unobtrusive, and it may go unnoticed by some.
