Being in Sweden, and thus nearer to the Arctic Circle than most places, Gothenburg experiences long, cold winters and short, but warm summers.  The city's latitude also insures that during the summer it receives several hours of sunlight per day, up to 20 hours in June, with the opposite taking place in the winter.  Days during the month of December in Gothenburg may see as little as 3-4 hours of sunlight.  The average temperature during the summer months in Gothenburg is in the mid 70's to low 80's, while the winter months average in the 20's.  July through September also sees an increased amount of rainfall over the rest of the year. 

Most visitors choose to visit the city during the summer and fall months because of the increased sunlight and agreeable weather when its beaches and water sports can be taken advantage of.  For an up to date weather forecast for Gothenburg, visit MSN Weather.
