Keeping outdoor diners cool during a heatwave comes down to three things: shade, the right furniture, and good airflow. With
UK temperatures reaching above 37°C in summer 2026, hotter summers and more frequent heatwaves look set to become the norm rather than the exception.
Preparing a restaurant, pub, or cafe for summer now needs to go beyond getting the look right. Keeping guests comfortable in extreme heat is just as important for keeping trade steady.
How Can Shade and Shelter Help Keep Diners Cool?
Shade is the most effective way to cool an outdoor space. Where a natural canopy of trees isn’t an option, a
shade or shelter structure fills the gap.
Flexible options such as
umbrellas or
parasols can be put up when hot weather arrives and taken down when they’re not needed. For year-round protection, permanent structures like
ascot shelters,
cabanas and beach huts, and
awnings are a better fit.
What Furniture Keeps Diners Cool in Direct Sun?
Nobody wants to sit on a hot surface during a heatwave. If part of your outdoor space gets high sun exposure and doesn’t have shelter, timber furniture is the better choice. Our
timber benches and
tabletops are good examples, since wood stays noticeably cooler to the touch than metal or plastic.
How Do Cushions Help With Metal or Plastic Seating?
Metal and plastic furniture can still work well in a heatwave with the right accessories. Adding
cushions, blankets, or covers keeps seating comfortable, and as a bonus, these accessories also give a space a more inviting summer look, which can help attract more customers.
Does LED Lighting Help Keep Outdoor Spaces Cool?
Lighting is an easy source of heat to overlook. Even once summer evenings start to cool down, they can still feel warm and clammy.
LED lighting stays cool during use, so it doesn’t add extra heat to the space, while still giving a soft, inviting glow that appeals to guests.
How Should Seating Be Arranged for Better Airflow?
Spacing seating out properly helps diners stay cool by allowing wind to move through the space more freely. Well-spaced tables also give everyone more personal space and make it easier for staff to move around and serve without brushing past guests.
Can Planters and Landscaping Provide Extra Shade?
Strategic placement of
planters and foliage adds natural shade throughout the day, while also giving a space a more stylish finish that can help attract passers-by.
What Other Steps Help Keep Guests Cool During a Heatwave?
- Incorporate misting systems for extra cooling in high-heat spots
- Promote outdoor events during the cooler times of the day
- Be prepared to change the layout of outdoor spaces regularly
- Offer free water for dogs if you run a pet-friendly establishment
FAQs
What is the most effective way to keep an outdoor dining area cool?
Shade is the single biggest factor. A combination of permanent structures such as ascot shelters or awnings, plus flexible options like parasols for peak heat, covers most outdoor spaces effectively.
Is wooden or metal furniture better for hot weather?
Wooden furniture stays cooler to sit on in direct sun than metal or plastic. Where metal or plastic seating is already in place, cushions or covers make it comfortable again during a heatwave.
Do umbrellas or parasols work better than permanent shade structures?
Umbrellas and parasols are better for flexibility, since they can be put up when a heatwave hits and taken down when not needed. Permanent structures like ascot shelters or cabanas offer year-round protection but suit venues with consistent shade needs.
Can lighting affect how warm an outdoor space feels?
Yes. Traditional lighting can add noticeable heat on a warm evening, while LED lighting stays cool and doesn’t contribute extra warmth to the space.
How should seating be arranged during a heatwave?
Well-spaced seating improves airflow around each table, helps wind move through the space more easily, and gives staff room to serve without brushing past guests.
