Thousands of people were out and about during the weekend enjoying a packed timetable of events across the county.
Agricultural shows, community festivals, flower festivals and vintage car runs were just some of the activities taking place as residents refused to let the showers stop them continuing the party spirit of the jubilee celebrations.
The Nautical Training Corps held their annual founder's celebration and mini tattoo on Hove Lawns on Saturday and Sunday.
Youngsters taking part wrote messages of congratulations in a jubilee book that will be sent to the Queen.
The highlight of the celebrations was a parade along Hove seafront and service of remembrance on Sunday morning, with 1,000 officers and cadets taking part.
On both days visitors got the chance to experience marching bands, drill displays and an abseiling tower.
As scores of football fans across Sussex nursed hangovers after England's victory against Argentina, others braved the pouring rain for Queen and country.
Hundreds of army cadets from Sussex crammed into St Martin's Church in Brighton to mark the jubilee and Cadet Sunday.
After the service, the cadets marched past a group of dignitaries, including the Lord Lieutenant of East Sussex.
The guest of honour was 16-year-old Stephen Menary, a cadet who lost a hand and his sight handling a terrorist bomb outside his barracks in West London.
Stephen has been receiving treatment and advice at St Dunstan's home for the war-blinded in Ovingdean.
Some of the money collected at the service will go towards his continued rehabilitation.
Slightly luckier with the weather were the dozens of tots who enjoyed a sponsored toddle on Saturday.
A puppet show, Harry Potter bouncy castle and a giant teddy bear were among the attractions at Preston Park, Brighton, for the Push 'n' Toddle and teddy bears' picnic.
Organiser Wendy Smith said dozens of youngsters enjoyed the activities and about £500 was raised for the Brighton and Hove branch of the National Childbirth Trust.
She said: "We are now hoping it will be an annual event."
The annual Burgess Hill festival got off to a flying start with Burgess Hill Marching Youth Band playing resounding numbers along Church Road.
The rest of the carnival followed behind with floats from Burgess Hill and District Lions, Tesco social club and Amex.
A carnival was held in St John's Park with displays, attractions, stalls and games, and the Liberal Democrats held an afternoon tea party.
Historian Malcolm Campbell led a guided walk called Haunted Wivelsfield from Wivelsfield railway station and local band the Echotones provided the evening entertainment.
Burgess Hill Theatre Club presented its version of Alice in Wonderland in the Market Place Shopping Centre where the young actors and actresses formed a circle to perform, having made all the props themselves.
The festival continues throughout the week.
Elsewhere, customers said a fond farewell as a family business shut up shop for the final time.
Ted Homewood, who has stood behind the counter of Homewood Stores in Elm Grove, Brighton, for 48 years, struggled to reply due to a sore throat.
The convenience store was bought by his father, Ted Homewood senior, in 1935.
Assistant Ian Rolf said Ted wanted to thank everybody for the cards and good wishes and for all the loyal customers over the years.
In Shoreham, the Beach Dreams festival continued with samba music and guitarist Richard Durrant.
More than 17,000 people visited the last day of the South of England Show at Ardingly on Saturday.
The highpoint of this year's show was a visit from the Queen and Duke of Edinburgh.
Carola Godman Law, chairwoman of the South of England Agricultural Society, said: "We are delighted so many people turned out to support the society, farmers, rural businesses and the countryside.
"The jubilee visit was a wonderful occasion and everyone thoroughly enjoyed themselves."
The nine-day East Preston Festival also began on Saturday, with a grand festival fete.
There are more than 65 events going on during the rest of the festival, including a festival queen contest, carnival procession, art and flowers exhibition, antiques and collectors market and an open gardens' day.
The festival runs until June 16.
Festival-goers were also in carnival mood on Saturday for Durrington Festival's "Big Day".
Events included a colourful carnival procession through the streets followed by the annual village fayre.
The theme of this year's procession was the Golden Jubilee and many floats were decked out with Union Flags.
The procession of about ten floats wound its way on a mile-long journey through the streets from West Durrington to Pond Lane recreation ground.
Gary Davis, on the festival committee, said: "The carnival procession was a huge success. Everyone was wearing red, white and blue and some of the people had dressed up as English kings and queens."
The festival concluded on Sunday afternoon with an inter-pub boules challenge.
In Hailsham on Saturday, a charity toy, cake and book sale at the Central Avenue Community Centre in Eastbourne raised £570.
The event was organised by Julia Lockyer, of The Paddocks, Hailsham, in aid of the Meningitis Research Foundation.
Her son, James, contracted meningitis at three months old.
James, now four, made a full recovery but Julia has helped raise almost £10,000 for the charity.
It was the last day of the Festival of Flowers at Chichester Cathedral on Saturday.
Thousands of visitors converged on the cathedral for the three-day event, which included 50 displays on the theme All Glory Laud and Honour.
Organisers aimed to raise £150,000 from the event towards restorations at the cathedral.
In Henfield, classic car owners revved up for The Golden Jubilee Run to Stanmer Park on Sunday.
The event, organised by The Starting Handle Club, included cars dating back to the Twenties.
The car run started from Henfield High Street at 1.30pm.
The Eastbourne Lions Classic Motorcycle Rally was also held on Sunday.
The rally started from the Wish Tower on Eastbourne seafront at 11am and travelled a 60-mile route around the Sussex countryside.
Sue Holden, fund-raising chairwoman of the club said: "We had 211 classic motorcycles taking part and 260 riders.
"Everybody enjoyed themselves and it only started raining as the last bikes came home."
