In the Northern Hemisphere, it is October through March(some say through April) for the "seasonal flu".
In the Southern Hemisphere, it happens in the opposite time of year from the Northern Hemisphere. It is in the Southern Hemisphere's winter (during the US summer) from April through September.
There can be differences between climates within each of the hemispheres, too. For example, in the US in Texas, flu season is from November to to April, while in Iowa, flu season is from December to April.
Seasonal flu vaccinations should be obtained any time beginning in September through March to be effective for that season in the Northern Hemisphere.
See the related question in the related questions section about why the flu has a season. Interestingly, you will see that in some locations in the world the flu season is during the warmer times and not in fall and winter. It is more the effect of absolute humidity and not the temperature itself that makes that difference. In areas with the flu season in warmer months, the absolute humidity is lower then, making the dry conditions that influenza viruses prefer despite warm temperatures. In the US, the absolute humidity levels are lowest during the peak of the flu season in January and February, the colder season.
In the Northern Hemisphere, it is October through March(some say through April or May in the colder regions) for the "seasonal flu".
In the Southern Hemisphere, it happens in the opposite time of year from the Northern Hemisphere. It is in the Southern Hemisphere's winter (during our summer) from April through September.
In the Northern Hemisphere, it is October through March (some say through May especially in the colder regions) for the "seasonal flu".
Autumn (Fall) starts on September 22 for 2008.

It is usually said that the Southern Hemisphere has the flu season from April through September. It is October through March (some say May) in the Nothern Hemisphere.

what date is the officially end to the flu season 2014
There are many websites that offer information about the flu season. The CDC, TexasFlu, flu.gov, and immunisation websites all offer helpful information about the flu season.
Once flu season is over....which I think is may or June...but when flu season comes back around november, so does the swine flu.

They are available now. In fact, in the 2010-2011 flu season in the Northern Hemisphere, the regular seasonal flu vaccination includes the vaccine for H1N1/09 (swine flu). If you already had the vaccine in the 2009-2010 season, it will not harm you and might help you to get it again along with the vaccines for the other flu viruses expected in this flu season.
It probably won't suddenly stop spreading, but it dies down after each flu season. It comes back during the next flu season though.
Last flu season, 2009-2010, you needed two shots. But this year the seasonal flu shot also protects against swine flu, so, in the US, you only need one flu shot for the 2010-2011 flu season.
They usually are available a month or so before the start of the flu season. In the Northern Hemisphere and US that is around September since the beginning of the flu season is October.
The swine flu is no longer a pandemic. Outbreaks are still occurring in some places of the world. It really didn't involve only the flu "season" but also was spreading in spring and summer, not typically times for the flu. At present (spring 2011), the northern hemisphere is in the flu season which is usually defined as the period from October until April in the northern areas. One of the types of flu that was anticipated and that has been active during this flu season is the H1N1/09 Swine Flu. That is why this year's flu season vaccine incorporated the swine flu vaccine as one of the three in the seasonal trivalent flu vaccination for 2010-2011's flu season. Ohio is included in this flu season of October to April, so since it is currently mid March 2011, the flu season will be over in Ohio in a few weeks. However, just because the season is over, does not mean you can not still get the flu, especially since we know that the swine flu began in spring 2009. Most people do not get a flu vaccination after the end of March, however, since the time to become immune from the response to the vaccine is longer than the season usually lasts from that point. There is still some risk, so some doctors continue to give the vaccine through the end of March. It is important to get the seasonal flu vaccination each year in the early fall in the Northern Hemisphere to prevent the flu.
They don't shoot you, and it isn't a 'shot' of a drink, it's a needle in the arm. In the 2009-2010 flu season there was a mist as well as a shot for the vaccination for swine flu. In the 2010-2011 flu season the vaccine for swine flu protection is included in the one vaccination for the seasonal flu.
As of the 2011-2012 flu season, it is still circulating in isolated outbreaks. In the Northern Hemisphere there are scattered outbreaks seen. It is expected to be one of the three most common types of flu during this flu season and, therefore, the seasonal flu vaccination protects against it again this year.
During fall and winter.
