The three most essential components of any barbecue party are the guests, the weather and the food. I can not make suggestions about your friends and family, you are on your own there, but I hope you will find my suggestions for the other two fronts practical.
An impromptu party in the garden is great and often the best parties are the ones that just happen off the cuff, but if you want something a little more formal or more impressive then you have to organize. The first step is to pick a date far enough in the future for most people to be unlikely to have a previous engagement, but not so far that they might forget about your barbecue party.
Depending on where you live of course, try to pick a date when it is unlikely to be cool or wet. This is hard in places like the UK, but may be simpler where you live. If the party goes on into the night it may get cool anyway and you could hire a few gas patio heaters in advance just in case. You could also have a sunshade or sheltered seating area in case of blazing sunshine or a light shower.
These days many people are vegetarian and you will have to plan in advance for them and other dieters, if they make up a sizable number of your guests. You could send out RSVP invitations and ask your guests to make known any special dietary requirements. I am not really suggesting that you have to cater to everybody, but if you have a lot of Jews or Arabs coming you will need to provide an alternative to pork chops and of course there are other minorities too.
In fact, you may have to do some investigation into the religions of the people coming to your barbecue party, because often cooking utensils may not have touched pork of meat or shellfish. Most people of the guests with these dietary needs will have been in this situation before and will appreciate if you go some way to providing an alternative.
For this reason, you will need to get your RSVP cards back at least a week before your barbecue party and do a bit of research on the telephone or the Internet. Then start making up the barbecue side dishes. These should include baked or and boiled jacket potatoes and potato salad, baked beans, egg quarters and coleslaw along with pickles, relish, onions, chutneys tomato and curry sauces (hot and not so hot), as most people will eat them. These can be prepared a few days in advance and kept in Tupperware containers in the fridge. Bread in the form of buns is also essential so that people can make sandwiches.
It is imperative for a polished act, to have your party area fully prepared before your guests turn up. it is a good idea to set the music system up in the garden shed or the garage to save it from any sudden shower. Provide plenty of tissues for wiping greasy fingers and plenty of receptacles for the debris. Finger bowls with lemon water would be a good idea for this purpose too.
