Oxford’s annual Double Decker Arts Festival is always a winner, but there’s no denying its scale of greatness has everything to do with the weather.

That’s the one thing Visit Oxford and city planners can’t control, and we’ve experienced a little bit of everything in more than 20 years of Double Decker fun — temperatures in the 50s, light showers, heavy downpours and hot, warm temperatures.

Local weather forecasts have been worked over this week by many in Oxford, with organizers frequently checking for updates to see the latest forecast for this weekend’s Double Decker festival. At times, rain has appeared likely.

But here’s good news: the closer we get to Saturday, the better the forecast looks.

At the moment it appears cloudy skies will prevail Saturday morning and summer-like conditions with partly cloudy skies overhead until at least midnight.

That would be long enough to get the festival in as another big winner.

It’s not that rain will dampen it all if it does come. But we all know Double Decker is best when you don’t need an umbrella.

If the current forecast holds, with temperatures reaching into the upper 80s Saturday, the city may experience more than 60,000 for another Double Decker weekend of greatness.
