Although Frøya is a variant of the name of the Norse goddess Freyja, the Old Norse form of the name of the island was Frøy or Frey (the ending -a in the modern form is actually the feminine definite article – so the meaning of Frøya is 'the Frøy').

Until 1906 the island and municipality name was spelled Frøien (-en is the masculine definite article in Norwegian).

The official blazon is "Azure, three fishhooks argent in bend" (Norwegian: I blått tre sølv angler i skrå rekke).

This means the arms have a blue field (background) and the charge is a series of three fish hooks lined up diagonally.

The fish hooks have a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used.

The main island of Frøya is fairly open and has no natural forests–mostly covered with marshes and heather.

[1][13] Frøya has a temperate oceanic climate (Cfb) with a year amplitude of only 11.2 °C (20 °F) from the coldest to the warmest month.

November and December are the wettest months, while April – July are the driest part of the year.

The municipal council (Kommunestyre) of Frøya is made up of 23 representatives that are elected to four year terms.
