Forecasting the future for businesses – What’s the best weather for selling chocolate? Earlier this year Thorntons, which had 369 UK shops before an announced programme of closures, said the unseasonably warm weather in the run-up to Easter had hit sales and would cut the company’s full-year profits. So not hot, then. But back in February the company complained that the freezing temperatures and heavy snow last December meant delivery lorries couldn’t get through to the shops. Yuletide sales were down by £3.5m. So not cold either.
