Risk identification and contingency
Event weather contingency coordination
Part of your programme touches the outdoors, whether it is a welcome drinks terrace or the walk from the car park, and no one has said who decides when the weather changes.

The short answer
Weather contingency is a set of decisions made in advance: what you will watch, at what point a named person decides, what the alternative is and who tells delegates. Agree these with the venue before the event so that on the day nobody improvises.
The forecast is not your decision to interpret alone. Ask the venue which official sources it relies on and whether it has its own rules for outdoor areas, and record what it tells you.
Start with where weather touches the programme
List only the parts of the programme where weather changes what delegates experience or what suppliers can do. For a professional event in Kuala Lumpur or Selangor this is usually a short list: arrival and drop-off, any outdoor reception or break, a site walk, an exhibitor load-in or a photo session.
Each item on the list needs its own decision, because the indoor option for a networking dinner is not the same as the option for a morning arrival.
Triggers, owners and options
For each exposed item, write the trigger, the decision owner and the alternative in one row. Triggers should be observable and time-stamped, not feelings.
| Programme item | Trigger to review | Decision owner | Alternative to confirm |
|---|---|---|---|
| Outdoor reception | Venue weather advice or official warning at a named check time before the item | Event owner, after consulting the venue manager | Indoor room, its capacity for this group and set-up time, confirmed by the venue in writing |
| Delegate arrival | Venue or road-side advice affecting drop-off or covered walkways | Project lead or registration lead | Covered route, staff positions and a message to delegates |
| Exhibitor load-in | Supplier or venue advice that load-in is unsafe or blocked | Venue operations with the exhibition supplier | Revised load-in window agreed with the venue and suppliers |
| Speaker or VIP travel | Flight or transport delay notices | Project lead with the speaker's contact | Programme swap or moderator extension, see speaker absence |
What to ask the venue in writing
- Which official forecast or warning sources does the venue use, and who at the venue makes the call on outdoor areas?
- What rooms can serve as the indoor alternative for each outdoor item, and how long does the change-over take?
- Does moving a function indoors change the room hire, catering or insurance terms, and who approves that?
- What is the venue's own process for severe weather, and how will it tell the organiser?
- Which areas does the venue close or restrict, and at whose decision? Record the answer as the venue's rule, not yours.
Keep decisions and messages separate
- Name one decision owner per item and a deputy for when they are travelling.
- Fix a check time for each item, for example at a stated hour before it starts, and record who checked.
- Prepare two short delegate messages in advance: one for keeping the plan, one for moving indoors. Approve both before the event.
- Put the decision and its time in the day's log so suppliers see what changed.
- Review afterwards: which triggers were useful and which were noise?
Money and time effects
A change of room can alter cost, set-up time and catering numbers. Use the contingency scenario calculator to see the effect of each option, keeping base cost and reserve apart. Adjust the run of show in a controlled way so that supplier call times are confirmed, not silently shifted.
Worked example · Fictional example
A terrace welcome drinks for a fictional forum
Fictional organisation and figures, for illustration only.
A fictional professional-learning forum for about 180 delegates plans welcome drinks on a hotel terrace. The project lead asks the hotel which weather sources it uses and who decides to move functions indoors. The hotel names its duty manager as the decision-maker at a stated hour before the function.
Together they agree a trigger row: at that check time, if the duty manager advises moving indoors, the event owner confirms within a set period, the lead sends the pre-approved message, and the AV supplier is told the new room. The ballroom foyer is confirmed in writing as the alternative, with the venue's changeover time recorded.

- Venue's own rule or restriction, and who at the venue applies it:
- Cost or time effect of the alternative, and who approves it:
- Pre-approved delegate message (keep plan / change plan):
- Suppliers to be told, and by whom:
- Log entry: decision, time, person:
Handle it in-house, or bring in help?
Your team can usually handle this when
- Only one or two items are exposed and the venue has a clear indoor option.
- The venue has written weather rules and a named duty contact.
- The organiser has an authorised person who can decide quickly on the day.
Outside planning help earns its fee when
- Several outdoor items, multiple suppliers and more than one venue area are involved.
- No one is sure who can approve extra cost for a room change.
- The programme has external travellers or a site visit that depends on third parties.
Want the weather decisions written down once?
A planning diagnostic can review your programme for the items that depend on weather, list the unresolved decisions with the venue and suppliers, and produce a prioritised action plan with owners and dates. The venue and authorities keep their own decisions about outdoor areas and closures.
Questions organisers ask
Can the organiser decide to cancel an outdoor function because of weather?
Usually yes for your own function, but the venue may have rules for outdoor areas and may restrict access itself. Agree with the venue in advance who decides what, and record it.
Which weather forecast should we follow?
Ask the venue which official sources it uses and follow the same ones, so the venue and organiser are not working from different information. Do not rely on a single app on one person's phone.
Should we always book an indoor backup?
Only where weather changes the experience materially. Ask the venue what an indoor alternative would cost and how long set-up takes, then decide with finance using the planning diagnostic list of open decisions.
What if the weather affects delegate travel and not the venue?
That is a transport matter. Use transport disruption coordination for delegate arrival, and keep this sheet for the venue-related items.
