Themes for Parties in September

September marks the beginning of a new season and that in itself is a reason to celebrate. If you are in the Northern Hemisphere, September is the first month of Fall or Autumn. Fall is the start of some milder weather so it’s a great time to have an outdoor Fall themed party. It’s also the start of football season so another great reason to get friends together.

If you are in the Southern Hemisphere, September marks the end of winter and a Hello Spring party is definitely a great idea. As the days start to get longer again it’s a great time to entertain with friends and family. Spring is the season of new beginnings so let’s shed our winter skins and celebrate.

September Birthday Ideas

People that celebrate their birthday in September have either the star sign of Virgo (1 – 22 September) or Libra (23 – 30 September).  You could have a Virgo themed party celebrating that special Virgo in your life. It’s hard to find Virgo party decorations in your local store so here are some great Virgo themed party decorations to make your party extra special.

Likewise if you’re looking for Libra themed birthday decorations check out this awesome set below to up level your party theme.

September Party Ideas

A favorite and fun party theme that would suit a September party is a Celebrity Dress Up party. The catch is that the famous person you dress up as must also have a September birthday. But to make it easier, if you choose an actor you can dress up as a character they played in a movie. Michael Keaton has a birthday in September so a Batman costume would work for this party theme. Tommy Lee Jones aka the Joker in Batman forever, or  Linda Hamilton aka Sarah Connor from the Terminator.

Male celebrities / famous figures that were born in September include: Keanu Reeves, Charlie Sheen, Damon Wayons, Michael Keaton, Will Smith, Freddie Mercury, Lil Wayne, Bruce Springsteen, Tommy Lee Jones, Hugh Grant, Roald Dahl, Ray Charles, Buddy Holly, Dr Phil, Lance Armstrong, Prince Harry.

Female celebrities / famous figures that were born in September include: Beyonce, Gwyneth Paltrow, Heather Locklear, Serena Williams, Catherine Zeta Jones, Linda Hamilton, Sophia Loren, Olivia Newton-John, Fran Drescher, Brigitte Bardot, Jenna Marbles, Pink.

Father’s Day Party / Celebrate Family Party

Fathers Day (1 September) & Grandparents Day (8 September) & Family Day (23 September)

On the first Sunday in September families in Australia celebrate Father’s Day. A great day to celebrate the awesome fathers, grandfathers and male carers in the family. Even if you’re not located in Australia why not celebrate those awesome dads out there.

It’s a very family-centred month with Grandparents Day as well as Family Day in September. Another great reason for an inter-generational family party or gathering to celebrate extended family.

Superstitions Party

Friday 13th (13 September)

This year Friday the 13th falls in September. This date has many superstitions attached to it and it’s lucky for some unlucky for others. Why not plan a Superstitions party? Decorate your party with black cats, ladders, number 13, open umbrellas inside and anything else you can think of. Start searching for superstitions and see how many you can feature in your party. It would be a super fun way to get ready for the Halloween season and a really unique party theme.

You could have photos and messages decorating the party area honoring those who you are grateful to have in your life.
