What Autumn Weather Means for Outdoor Events in the UK

If you are booking an outdoor event for October or November, the weather question feels different to the one you would ask about a July festival. It is not really "will there be a shower", it is "how much of the day will be wet, and how cold will it be while it is". Autumn in the UK is a different weather season to summer, not just a colder one, and it is worth planning for the difference rather than assuming the same kit and the same mindset will do.

Why autumn rain behaves differently

British summers get a lot of their rain from short, local downpours: warm, moist air rises quickly and dumps a burst of rain that can clear in twenty minutes. Autumn rain tends to come from a different source: larger weather systems moving in off the Atlantic, bringing longer, steadier spells of rain and wind rather than sharp showers. That is why an autumn event is more likely to see a grey, damp afternoon than a dramatic squall, but it is also why the wet spell is less likely to simply pass through.

The days are shorter too, which matters more than people expect. Standing outside in October drizzle in fading light is a different experience to a warm evening downpour in August, even if the rainfall total on paper looks similar. Organisers who plan for autumn well tend to plan for the cold and the dark as much as for the rain itself.

Planning around it, not just hoping it holds off

A few things make the biggest difference for an autumn outdoor event:

• Ground, not just sky. Autumn ground has usually had weeks to get wet already, so a modest amount of rain on the day can mean worse underfoot conditions than the same rainfall would in a dry August. If there is grass or unpaved ground involved, budget for matting or hardstanding earlier than you would in summer.
• Warmth for people standing still. Queues, outdoor markets and anything with a fixed viewing spot need more thought about shelter and heating in autumn than in summer, because cold combines with damp to push people indoors or home early.
• A realistic forecast check close to the date. Long-range seasonal outlooks are not much use for a specific afternoon in six weeks' time. The forecast that matters is the one issued close to the event, for the actual window your event runs in.

None of that stops an autumn event working well. Bonfire nights, outdoor markets, half-term shows and late-season fairs run successfully every year in exactly this weather. It is just worth planning for the weather that autumn actually brings, rather than the one that made your summer event good.

Where cover fits in

This is exactly the kind of uncertainty Rainy Refunds exists for. Rainy Refunds is rain cover for your event: you agree a rainfall trigger and a time window for your venue when you buy the policy, and at the agreed check time we take the Met Office forecast for that window and compare it with your trigger. If the forecast meets or passes the trigger, your payout is sent automatically, with no claim to make and no form to fill in. It is settled on the forecast for your window, not on how wet it turns out to be where you are standing, so there is nothing to argue about after the day.

Rainy Refunds policies are underwritten by Tokio Marine HCC. Rainy Refunds Limited is an Appointed Representative of Stubben Edge and Partners Limited, authorised and regulated by the Financial Conduct Authority.

You can see the events we currently cover, and buy cover in a couple of minutes if yours is on the list, on our Rainy Refunds page. The list is kept up to date through the season, so it is worth checking back as you firm up your autumn plans.
