Northern Spark happens rain or (moon)shine! There is no alternative rain date for the festival, so dress appropriately for the weather. Extreme weather may delay some projects or require projects to be altered.
In the case of weather-related changes on the night of the festival, check northernspark.org, contact individual venues, or ask at a Northern Spark Information Tent. Updates will be posted in real time on both Facebook and Twitter. Look for the #nspk hashtag.
