RHS Chelsea Flower Show 2017 weather forecast

Bright spring flowers in bloom

Tue 23 MaySat 27 May 2017

Chelsea plays host to one of the biggest flower shows in the country in May, the RHS Chelsea Flower Show. It has taken place at its current location since 1913 although its predecessor in Kensington began in 1862, under its previous guise of the Great Spring Show.

Exhibitors from the UK, and across the world, spend months preparing their displays to take to the show, hoping to be crowned with one of the show's top rosettes.

There are many awards available for those that create a garden or display for show. Awards range from Silver and Silver-Gilt to Gold. Additional awards - for example, Best Show Garden, the President's Award, Best Fresh Garden or Best Construction Award - are also given, some of which are specific to individual shows.

< London last 24 hours Issued at:

23-27 May - Will the displays be in full bloom at this year's Chelsea Flower Show? Check the local weather forecast.

The Chelsea Flower Show includes a wide variety of show gardens, some created by professional gardeners but others by amateurs of all abilities and ages. They will all be hoping to catch the eye of the judges and win an Award.

In 2016 The Telegraph Garden, designed by Andy Sturgeon, won the Best Show Garden gold award at Chelsea. The people's choice was God's Own County: A Garden For Yorkshire, designed by Matthew Wilson.

Exhibitors and spectators alike will be looking for warm, dry weather to keep their exhibitions in top condition and to enjoy all the sites of the show. 

For further information about getting to the ground visit the Royal Horticultural Society official website.

Check the London weather forecast before heading to the Royal Hospital, Chelsea and its extensive grounds, the home of the flower show.

In the video below, Toby Buckland looks at the impact of the weather on our gardens at this time of year. He gives useful tips on which flowers and vegetables to grow, optimal watering and how to harden off young plants.

You can check the weather forecast for other events through the Events Calendar.

If you're looking for content for your own website, take a look at our weather widget.

Whether you are displaying at the show or going along to admire the amazing gardens and floral displays, check the Chelsea weather forecast before setting off.
