Important: we officially know what the weather will be like on Harry and Meghan's wedding day

Warning: the above photo *might* be misleading.

Yes, ahead of Prince Harry and Meghan Markle‘s wedding – taking place on 19 May 2018 at Windsor Castle – there’s one element that remains somewhat unpredictable.

We’ve got a rough idea of what the cake will be, what the flowers will look like, the guests that will be attending and even the potential designers for Meghan’s dress – but what the weather will be like on the day has to be waited to be seen.

With that being said, thanks to the joys of weather forecasting, we can at least make a stab at guessing whether it’ll be rain or shine.

According to the Met Office, 19 May in Windsor is looking largely dry with partial sunshine.

Hallelujah!

The day will see highs of 18 degrees and lows of six, with the sun expecting to set at 8:53 PM – meaning a nice spring evening for all guests attending the reception at Frogmore House.

A spokesperson from the Met Office said: “We have a good indication of what the weather is likely to be for the royal wedding – it is going to be mostly settled this week and that will continue on in to the weekend.

“It will be mostly dry with sunny spells with perhaps a northerly or northeasterly breeze. We can’t rule out a shower although to be honest that’s looking quite unlikely at the moment.

“Temperatures will be about normal for the time of year with highs of 17 or 18 degrees and during the sunny spells it will feel pleasantly warm.

“It’s looking like good weather for a wedding – you wouldn’t want it to be too hot.”

The Duke and Duchess of Cambridge had similar luck on their wedding day on 29 April 2011: it was cloudy with breaks of sunshine over lunchtime and it remained dry all day.

Some even speculated that the couple had used a £100,000 ‘cloud-bursting’ service, offered by luxury travel company Oliver’s Travels which guarantees customers a cloud-free wedding day.

The technique – which uses silver iodide crystals dispersed into rain clouds causing them to disappear – was used to prevent rain during the opening and closing ceremonies of the 2008 Beijing Summer Olympics.

Though the likeliness that the royals actually used this is very, very slim. Still – interesting stuff.

We’ve got all our fingers crossed for you Harry and Meghan.
