Not all trade show events are held inside in an air conditioned venue – many are held in the Great Outdoors, and planning for them means you have to take several factors into consideration. Notably, the weather is a big factor but there are plenty of other things to take into consideration, not least because of the potential for different visitor habits.
The Weather
Your trade show display must be able to stand up to the elements. You will need a water proof display which is unaffected by the wind and rain, and especially your graphical elements need to be weatherproofed.
In addition, the trade show display must be able to withstand windy conditions. If you are using a popup display in particular, you must take proper steps to ensure it is anchored properly, or risk having it blown over or away in the wind (remember banner displays and the like will look like a giant kite, so proper anchoring is essential).
Visitor Behaviors
Obviously, how the weather is behaving will influence visitor behavior, but you can work this to your advantage. If you have a sunny day, then being able to provide shade and the opportunity to cool down, perhaps augmented with some refreshments, this is going to make your trade show booth that much more attractive.
Conversely, if there is rain, again being able to provide shelter from getting wet is also going to help visitors to choose your trade display to be the one they hang out in.
Trade Show Accessories & Safety
Think carefully about the safety aspects of your outdoor display, particularly the lighting and electrical setup. Water and electricity clearly do not mix, so you need to ensure that all of your electrical setup will comply with all safety requirements (and exceed them).
Your trade show flooring is also a major consideration – ideally you want flooring which can be easily and simply cleaned, and this also applies to the trade show display. Tension fabric is a great idea for the display itself because it is machine washable, but again, this needs to be correctly anchored to avoid being blown around.
