The Bristol balloon festival is due to begin within hours with mostly dry, settled weather expected across the weekend. West weather forecaster Ian Fergusson said high pressure will dominate, with temperatures rising into the mid to high 20s C by Sunday.
“Overall, it will be a very pleasant set of conditions for this year's fiesta,” Fergusson said. He added that “the fiesta will have escaped any risk of inclement weather.”
That outlook matters because thousands head to Ashton Court for three days of mass ascents and night glows if the weather allows. Jo Bailey, a hot air balloon pilot, wants to break the record for the most ascents by one person.
Ian Fergusson and Friday
Friday should start the weekend on a softer note. Fergusson said temperatures are expected to reach the low 20s C, with variable cloud and sunshine and a very low chance of showers.
He said a few showers are still possible early on Friday moving into North Somerset off the Bristol Channel. That keeps the opening day close enough to the edge of change that crews and spectators will still be watching the sky, not just the timetable.
Ashton Court on Sunday
Saturday is forecast to turn warmer, with temperatures rising into the mid-20s. By Sunday, Fergusson expects the mid to high 20s C, with conditions becoming somewhat breezier during the afternoon.
He also said there is some forecast uncertainty about the possible southward progress of a very weak and decaying front on Sunday. The weather remains broadly favourable, but that front is the one feature that could still complicate the final day.
UV levels and pollen count are expected to stay high throughout the three days. For people heading to Ashton Court and planning to stay for the mass ascents or night glows, the practical reading is simple: the weekend looks usable, but Sunday afternoon carries the most uncertainty.
