The name Lumi is a girl's name of Finnish origin meaning "snow". Lumi and is often added to lists like Remarkable Weather Baby Names and discussed in our forums with posts like "Names on NB that make you go WOW!".
From the experts:
Lumi may be a rare girls' name in the USA and England, but it comes in the Top 50 in Finland, where it means snow. Given the popularity of Winter, Holly, Ivy and many other wintery-christmassy names, we think that short and spunky Lumi definitely has potential for greater usage outside its home country as one of the more unusual Christmas-Baby-Names">names for Christmas babies.
