Weather is a planning input, not a risk to accept

Decide the thresholds in advance and in public.

Outdoor events are exposed to conditions that affect structures, equipment, access and the audience. The failure is rarely the weather itself; it is a decision made late under pressure by somebody weighing a genuine safety consideration against substantial financial loss.

Setting thresholds in advance removes that. A stated wind speed at which temporary structures are cleared, a temperature at which additional water and shade arrangements come into effect, and a defined process for a lightning risk are all decisions better made calmly weeks earlier.

Communicating thresholds publicly, including to ticket holders, changes the dynamic considerably. An audience told in advance what would cause a delay accepts the delay very differently from one told at the time.

Structures and equipment have their own limits specified by the supplier, and those are the authority. Where an event's own threshold is looser than the supplier's specification, that is a serious problem rather than an operational choice.

It is worth adding that weather thresholds need somebody monitoring against them, which is a named role rather than a general awareness. Conditions change over hours and the person who would notice is usually the person most occupied with something else.
