This is what I found when I typed 'höst' in Svenska Akedemiens ordbok
(SAOB) on the internet ( http://g3.spraakdata.gu.se/saob/ ):
In the extreme south of sweden it has the same meaning as
English 'harvest'. In the rest of Sweden it is a season (between
summer and winter or the time you make the harvesting).
In modern Swedish 'höst' definitely means a season, not harvest.

In my own dialect, 'håst' (strong masculine noun) means a season
(approximately September to November, the time you make the
harvesting and a little bit more).

Because the extreme south of Sweden has the meaning of 'harvest', I
assume that Denmark also use it in this way, and Haukur probably
knows Danish better than Swedish.

In fact, 'höst' has a pure scientific definition in Sweden: it's the
time of the year when the average temperaure stays between 0 and 10
degrees Celsius during a longer period.

Finally, I quote the Bible (Swedish version of 1541):
"Åt höstenom när tu skalt inbergha kerffuanar." (Jes. 17)
