Saharan sand could turn Norwegian rain red

Norway may experience “blood rain” as sand from the Sahara mixes with rainfall, meteorologists report. While conditions appear favourable, no confirmed sightings have been recorded yet, according to Dagbladet.

Meteorologist Tone Christin Taule explained that strong high-altitude winds have carried Saharan sand northward in recent days. “In one way or another, the sand gets lifted into higher atmospheric layers,” she said. When this sand encounters rainfall, it can descend far from its origin, potentially tinting the rain a reddish-brown colour—a phenomenon known as blood rain.

“It will rain down some distance from where it started,” Taule noted, though she emphasised that visible effects require significant sand quantities. “You might notice it most clearly on cars or other surfaces once it dries.”

A red-tinged sun at sunset could also indicate high sand concentrations in the air, due to light scattering. While blood rain is harmless, Taule clarified that heavy sandstorms—unlikely in this case—could pose risks to air traffic.

Eastern Norway, which saw overnight rainfall, is the most probable region for any occurrence. However, Taule stressed that blood rain remains uncommon. “It happens occasionally, but I don’t have records of when it last occurred here.”

For most people, any traces would be subtle. “A bit of dust might remain after drying, but the rain itself would only show clear colouration with very large sand amounts,” she added.

Weather forecasts predict decreasing rainfall across southern Norway later today, with eastern regions seeing partial cloud cover. Northern Norway expects continued fair conditions, with temperatures around 10–12°C and only scattered coastal showers in Troms and Finnmark.
