The Hidden Reality of Running a Coffee Shop During a UK Heatwave

Does Hot Weather Hurt Coffee Shops? The Hidden Reality of Running an Independent Coffee Roastery During a UK Heatwave

When the UK experiences a heatwave, there’s an almost universal feeling of excitement. Parks fill with families, beaches become crowded, pub gardens overflow and barbecues seem to appear in every neighbourhood. It’s the sort of weather we spend much of the year wishing for.

Naturally, many people assume coffee shops must be thriving too.

After all, surely sunshine means more customers, more iced coffees and queues out of the door?

The reality is often far more complicated.

As the owners of an independent coffee shop and small-batch coffee roastery, we’ve discovered that prolonged hot weather changes almost every part of our business. Some changes are welcome, others are challenging, but all of them require careful planning, quick thinking and a willingness to adapt.

Here’s a look behind the scenes at what a UK heatwave really means for an independent coffee business.

The Biggest Myth About Summer in Coffee Shops

One of the biggest misconceptions is that warm weather automatically means busy cafés.

Sometimes that’s true, particularly in tourist destinations or coastal towns. But for many local, community coffee shops, trading patterns become far less predictable.

Daily routines disappear.

The morning commuter might decide to work from home. Families head to the coast instead of visiting the high street. People spend afternoons in gardens rather than shopping. By mid-afternoon, temperatures can become so uncomfortable that many simply stay indoors.

It’s not that people suddenly stop enjoying great coffee.

Life just looks a little different.

As a result, some days become unexpectedly quiet, while others can be incredibly busy with very little warning. Predicting customer numbers becomes much harder than during a normal week.

Coffee Doesn’t Become Less Popular in Summer

One thing we’ve learned is that coffee itself doesn’t become less popular during a heatwave.

People simply drink it differently.

Some customers swap their flat white for an iced latte.

People decide whether they want iced coffee, or cold brew and let us hope you decide by reading our guide!

Others choose a refreshing frappe or a fruit smoothie instead of a hot drink.

Many still enjoy their morning coffee exactly as they always have, just a little earlier before the hottest part of the day arrives.

Perhaps the biggest surprise is that our freshly roasted coffee beans continue to sell well throughout summer. Plenty of customers still enjoy brewing coffee at home, whether that’s as a traditional espresso, a refreshing iced coffee or a cheeky espresso martini in the garden, check out our recipe, here!

Coffee doesn’t disappear when summer arrives.

It simply adapts alongside the people drinking it. And so do we, with ice machines on 24/7, which also becomes a challenge as the hotter it gets, the harder it is to produce and keep ice ready!

Behind the Roastery Door

Serving coffee during a heatwave presents one set of challenges.

Roasting coffee presents another entirely.

While customers experience a cool drink in the café, behind the scenes our roaster is producing temperatures well over 200°C.

Even though our roaster is designed to deliver exceptional consistency, the surrounding environment always plays a part. When the roasting room is already exceptionally warm, every batch demands even greater attention.

Cooling roasted coffee can take a little longer.

Ventilation becomes even more important.

Dayne begins to melt as he monitors the roasts.

Roast development needs careful monitoring to ensure every coffee tastes exactly as it should.

It’s one of those details customers rarely see, but consistency is everything.

Whether we’re roasting a smooth Brazilian coffee, a vibrant Ethiopian or one of our bold, volcanic-inspired coffees, every batch deserves the same level of care regardless of whether it’s five degrees outside or thirty.

Great coffee shouldn’t depend on the weather.

Ironically, one of our boldest coffees is Hot Lava Java, inspired by the volcanic landscapes of Indonesia. Thankfully, despite its fiery name, it tastes just as good brewed over ice on a hot summer’s day as it does as a rich espresso during winter.

The Balancing Act Nobody Sees

Running an independent coffee shop is often a constant exercise in balancing today’s customers with tomorrow’s uncertainty.

During a heatwave, that balancing act becomes even more delicate.

How many fresh cakes should be ordered?

How many cakes do we put out?

Do we need twice as much ice?

Will smoothies suddenly become our best-selling drinks?

How much fresh milk should we order if more customers are choosing cold drinks?

Too much stock creates unnecessary waste.

Too little means disappointing customers.

Unlike large chains with central warehouses and sophisticated forecasting systems, independent businesses rely heavily on experience, instinct and knowing their community.

Every decision matters.

Looking After the Team

When temperatures climb, it’s not just customers who feel the heat.

For our baristas, the café becomes an even more demanding place to work. Between steaming milk, preparing orders, running around serving customers and, in our case, roasting coffee on site, the heat can build surprisingly quickly.

That means looking after the team becomes just as important as looking after the business.

Regular water breaks, keeping cool where possible, rotating jobs between team members and making sure everyone has the opportunity to step away from the busiest parts of the café all become part of the day. Sometimes it’s the small things—a cold drink, an ice cold smoothie or a few minutes in the shade—that help keep spirits high.

A happy team makes a better coffee shop.

Customers often remember a warm welcome just as much as they remember a great flat white, and that starts with making sure the people behind the coffee feel supported, whatever the weather.

Looking After Our Four-Legged Visitors

One thing we love about summer is seeing so many dogs visiting with their owners.

At Acorns Coffee, we’re proud to welcome dogs, and during a heatwave they deserve just as much consideration as everyone else.

Fresh water is always available.

Shadier seating quickly becomes the most popular choice.

Many owners sensibly visit earlier in the morning or later in the afternoon when pavements are cooler and walks are more comfortable.

It’s a lovely reminder that cafés aren’t simply places to grab a drink.

They’re places where communities gather—two-legged and four-legged alike. And find out more about our dog friendly coffee shop, here.

Coffee Shops Become Community Spaces

There’s something special about an independent coffee shop during extreme weather.

Some people visit for an iced latte after walking around the shops.

Others arrive to escape working from home for an hour or two.

Friends catch up over coffee.

Cyclists stop for a well-earned break.

Parents enjoy a quiet moment while the children cool down with a cold drink.

In many ways, cafés become little pockets of normality.

A familiar place where the conversation continues regardless of the temperature outside.

That’s one of the things we value most about being part of our local community.

While Summer Continues, Autumn Is Already Being Planned

Perhaps the biggest surprise is that, while everyone else is enjoying summer, we’re already thinking about the seasons ahead.

Coffee buying doesn’t stop because it’s sunny.

Roasting doesn’t stop. We pride ourselves on fresh coffee - learn more, here.

Planning certainly doesn’t stop.

The coffees that appear on our shelves in autumn often require decisions months in advance. New origins need tasting. Packaging has to be prepared. Seasonal collections begin taking shape long before the leaves start changing colour.

Running a coffee roastery means always looking ahead while continuing to serve today’s customers with the same care and attention.

The calendar never really pauses.

More Than Just Sunshine

Every season brings its own opportunities and its own challenges.

Winter mornings bring queues for hot chocolates and freshly roasted coffee.

Spring introduces new origins and brighter days.

Autumn welcomes comforting flavours and crisp mornings.

Summer brings iced drinks, smoothies, sunshine… and a unique set of challenges that many people never see.

That’s the beauty of independent coffee shops.

We’re constantly adapting.

Whether it’s roasting consistently in soaring temperatures, making sure the ice machine keeps up with demand, serving fresh coffee exactly the way our customers like it, or simply offering a comfortable place to take a break, every day looks a little different.

So the next time the forecast predicts another spell of glorious sunshine, we’ll probably be doing exactly what we always do.

Roasting coffee.

Welcoming familiar faces.

Making cold drinks, hot coffees and everything in between.

Because while the weather may change from week to week, our passion for great coffee never does.

Summer isn’t just about visiting your favourite coffee shop. It’s also a season for experimenting at home. Whether that’s brewing an early-morning V60 before the day warms up, making a refreshing cold brew, or pouring espresso over ice, freshly roasted coffee offers plenty of ways to enjoy great coffee, whatever the temperature.

The weather forecast might decide whether people choose a flat white or an iced latte. It might change how many smoothies we make or how much ice we get through before lunchtime. But one thing never changes. Every morning, we’ll still unlock the doors, fire up the roaster, welcome familiar faces and do our best to make someone’s day a little brighter—one cup at a time.
