On Halloween night, the full moon shines throughout the northern hemisphere.

This is a rare event, says the American Farmer's Almanac, which followed the year cycle closely since 1818.

Where the full moon hits the night between October 31 and November 1, on average every 18 to 19 years, it was last seen throughout the northern hemisphere in 1944.

In the United States, it is also customary to give names to adults and the Halloween moon is known as the “Hunter’s Moon” or “Blue Moon”.

However, despite its name, the moon does not shine blue, although this also occurs in connection with certain meteorological phenomena.

In Finland, however, seeing the full moon is likely to be a mere dream.

Most measuring stations have a full and thick cloud roof, says Foreca meteorologist Kristian Roine.

There is still a high cloud floating high above the lower cloud layer, and little is visible behind them.

- There is a small opening in the cloud cover on the border of South and North Savo and in Eastern Lapland.

Virtually the whole country is under a full cloud roof.

By the time of Estonia and Ladoga, the sky will be clearer and in St. Petersburg, for example, the full moon will shine bright.

A small crack in the clouds can also come at least to southern Finland, but according to Roine, it cannot be considered in any way probable.

- This is very typical of November, with the sky in the cloud, Roine.
