Forecasters are warning of another heatwave for the start of next week.
West Yorkshire Police has now issued advice to residents in a bid to tackle burglaries.
A force spokesperson said: “As the temperatures rise, so do opportunities for burglars.
“Open windows, unlocked doors and poor lighting can make your home an easy target – especially under the cover of darkness.”
They added: “Lock all ground floor windows and doors.
“Keep valuables – especially car keys – out of sight.
“Consider installing dusk-to-dawn lighting.
“Make sure your property is well-lit and visible.
“Remember – offenders don’t want to be seen.
“Let’s not make it easy for them.”
