Summer can change the rhythm of a London business very quickly.
A stretch of warm weather, a run of big events and more people moving around the city can lift sales in a matter of days.
It can also expose weak spots just as fast – patchy rotas, slow suppliers, tired staff, unclear pricing or a shopfront that looks as though no-one's thought about it since February.
For London SMEs, the season matters because the city gets busier in different ways, all at once.
Tourists arrive, Londoners spend more time outside and major events pull crowds into particular neighbourhoods.
The businesses that do well in summer aren't always the ones with the best idea. Quite often, they're the ones that got organised early.
The businesses that nearly always benefit from summer
Some sectors get a seasonal lift almost by default.
Think food trucks in parks and at events, beer gardens, ice-cream vans, florists near outdoor venues, beachwear and sunglasses shops, juice bars, bike hire businesses, market traders and cafés with a strong takeaway offer.
If that sounds like your business, you won't see a lack of demand. But success might actually catch you out.
Stock and suppliers
Look hard at stock, prep time and how reliable your suppliers are.
If you sell products with obvious warm-weather spikes, build a short list of your summer bestsellers now and ask yourself three simple questions:
What runs out first?
What takes longest to replace?
What frustrates customers most when it's missing?
For an ice-cream van, that may be cones, napkins and chargers for a card machine. For a beer garden, it may be glassware, fridge space and weekend staff cover.
