A contingency plan for inclement weather is a must when working in parks. This plan should include a rain date (if you choose to book one) as well as actions that may need to be taken in the event of bad weather (covering electrical equipment or displays, anchoring signage, furniture or other structures, etc.). Some artists prefer to book alternate dates in order to cancel in the event of inclement weather and others will proceed rain-or-shine. This may depend on the type of art or performance being presented and/or the degree of risk to attendees. Choose a weather contingency plan that best suits the nature of your event and that works within the resources you have available. Weather is something that can’t be controlled but there are steps you can take to mitigate issues it causes.
Natural and built structures can provide protection from harsh weather and trees provide some shelter from both sun and rain. But if trees are the only available shelter, consider renting a tent or tents. Renting a tent can be costly depending on the size and length of the event and, depending on local regulations, tent installation may require a building permit or other special permissions.
Consider booking a rain date in case you have to cancel and include this information in your event promotion. Clearly communicate your weather contingency plan and its components to all artists, staff and volunteers, and delegate specific roles. Practice these roles so everyone knows what to do.
