Weather statistics for Geilo, Hol (Buskerud)

  1. Warning sign

    Ongoing: Landslide risk. Caution level: yellow (Østlandet, særlig dalstrøkene østafjells)

    Relatively high temperatures causes significant snow melt. Risk of slush flows is especially high in areas with more than 40-50 cm snow. The snow may in some places be fully water-saturated. Areas with fresh snow are particularly exposed, since new snow may be saturated with water quickly. Slush flows are triggered even in gentle slopes, where water accumulates. Slush flows follow terrain depressions and may develop into debris flows. Read the full forecast on

      Danger is over

    Some landslides are expected. A few large events may occur. Exposed railways and roads may be closed. Debris avalanches/shallow slides: Soil slides and rapid movement of saturated soil in steep terrain. Debris floods: A "flood" of water, soil and rocks in steep creeks. Surface runoff in steep terrain can cause streams to change regular flow patterns. Slush slides: A flow of waterlogged snow. These landslides can start in relatively flat terrain and seek towards streams and steep slopes.Keep away from steep slopes, as well as streams and rivers with high discharge. Cleaning of drainage paths and culverts are recommended. Keep water paths and culverts free from snow, ice, sediments, waste, twigs and leaves.

Graph explanation. Hide explanation

The black line shows mean value (both precipitation and temperature). Some stations does not have mean values, and hence no black line.

The red/blue line shows average temperature during the day (24h) (equalized for 30 days). The line is red by pluss degrees, and blue by minus degrees.

The red/blue areas shows the temperature variations throughout the day (24h) with max- and min. temperature as endpoints. The area is red by pluss degrees, and blue by minus degrees.

The lightblue bars shows total precipitation this month. The black lines crossing is the normal (mean) value for precipitation.

The dark grey bars behind the precipitation bars shows snowdepth measured day by day.

Some stations only measures precipitation, while others only measures temperature. If an area or bar is missing the station does not measure this data.

NB! Precipitation is measured at 07 hours Norwegian time. The value (in mm) shows last 24 hours until 07 hours (08 hours summertime). Download other weather statistics from
