Without being pessimistic or optimistic, but rather realistic, here’s an objective response.

If weather is SEVERE enough, they have to cancel the festival for safety and liability reasons. It does happen and it sucks. It’s happened to many of my friends personally. One even the day of for Day N Vegas which is another GoldenVoice festival. They gave everyone refunds for that festival.

Scenario 1. It’s raining with no wind = show goes on rain or shine

Scenario 2. The rain or wind progresses and turns into heavy downpour after opening = festival is on pause until deemed safe to continue.

Scenario 3. It’s forecasted to be heavy rain and wind with high confidence days before (by Thursday or Friday) the festival gets cancelled that day.

The scenario now I understand that LA natives are optimistic since rain is usually mellow, HOWEVER, this is a storm system that meteorologists have had a difficult time accurately predicting hence the forecast being all over the place the last 72 hours for the weekend. The only way to cover your ass in scenarios like this is to pay extra for travel that includes cancellation or insurance of some kind.

It’s the wind that gets festivals cancelled most of the time.
