The first return of the Bristol Balloon Fiesta in full since the pandemic could be the hottest ever - with temperatures forecast to rise into the low 30s by the weekend - but there is another factor about the weather that could impact on people in Bristol experiencing the delights of the mass balloon ascents - the wind.
Forecasters are predicting the entire festival will see light breezes, which should mean all seven planned mass ascents take place, but the wind direction will mean little, if anything, will be visible from Bristol.
When the balloons take off from Ashton Court for the first time on Thursday evening - and for the rest of the next four days - an easterly breeze is predicted to blow the balloons gently away from the city and over the fields of North Somerset towards Long Ashton, Failand, Nailsea and Clevedon instead.
