Growing up in a Hotter Britain: are the places children play ready for a warmer climate?

The Met Office observational series shows a clear long-term warming signal. Average summer temperatures have risen by roughly 1°C since the 1960s, and extreme heat events that once occurred rarely are becoming more frequent. For children — whose bodies regulate heat less efficiently than adults — this means more days where outdoor play becomes uncomfortable or unsafe.

Deprivation and heat exposure are not evenly distributed. Bradford ranks as the 12th most deprived local authority in England. The most deprived LSOAs cluster in the urban centre and east — the same areas where tree canopy is thinnest, play sites are sparsest, and families are least likely to have private gardens. Heat risk, in other words, falls hardest on those with the fewest alternatives.

Adaptation is practical and proven. Tree planting, shade sails, permeable surfaces, and water play features can all reduce surface temperatures and extend the hours a playground stays usable. International evidence from Australia and the US shows that refurbished, shaded sites see sustained or increased use even during hot periods — without the need to build new facilities from scratch.

Bradford already manages 292 facilities across 163 sites. The opportunity is therefore not expansion but optimisation: directing shade, cooling and access improvements to the sites and communities that need them most. A data-led approach — mapping shade, deprivation and walking access together — ensures investment reaches the places where it will have the greatest impact on children’s daily lives.
