Weather forecasting is great, but is only really accurate up to about a week in advance, and we all know that the planning of an event starts months or even years before the day, so we have to have a wet weather plan in place. 

This could be as simple as making sure you are supplying enough marquees or gazebos for the most important attractions, and making sure that anything that could get damaged by the rain is under cover.

Especially important is any electrical supplies that are being used during the event. Event electrical safety is the responsibility of the event organisers, and you need to ensure the power connections and distribution equipment is designed for outdoor use. (For more about the importance of power management and how to manage power at your event, check out our blog posts).
Any equipment that is not design for outdoor use needs to be under cover and off the ground.

Something else to think about is when you get heavy rain on a showground the water directly from the sky is only one consideration. Flooding, or moving water, also has a big impact on how an event will cope with rain.
The positioning of all the attractions must be considered during the planning stages to ensure a successful day.

The final point we are going to make is not just about the day itself, but about the lead up to the event. 

How are you planning on getting vehicles on and off a grass showground if it’s wet? You might have studied the weather forecast and are happy it will only rain for the two days before your event, but on the day it will be fine. Will the ground be dry, and how much damage will all the traders and attractions do to the ground before the public arrive? It is always worth considering having some plastic trackway on standby, or at least factored into the event budget, so there are no nasty shocks on the day.
