Thomson, who is based in Gosport, was due to sail from France to Portsmouth Harbour this weekend after finishing second in the race last month.
But organisers called off the event as heavy rain and gale force winds have been forecast.
They said the event will be rescheduled for 11 or 12 February.
Bangor-born Thomson, 42, crossed the line 15 hours, 59 minutes and 29 seconds after winner Armel le Cleac'h - who set a record time of 74 days, three hours and 35 minutes.
Thomson had threatened to overtake Le Cleac'h with 309 miles left of the race before a malfunctioning autopilot ended his challenge.
He has now matched Dame Ellen MacArthur as the best British competitor in the Vendee Globe. She finished second in the 2001 race.
Thomson is expected to sail his boat Hugo Boss, surrounded by a flotilla of craft, in a parade down The Solent into Portsmouth.
Hundreds of fans are expected to attend the celebrations in the city and at Thomson's team base at Haslar Marina.
Organisers said full details of the rescheduled celebrations will be announced next week.

The Blue Cross charity centre had to throw out all 90 posts when they became saturated by drain water after torrential rain early on Friday.
All the animals were safe, although 15 kittens had to be evacuated from the nursery which was covered in sludge.
The centre has appealed for help to replace the posts and toys.
There are currently 46 cats and kittens looking for new homes at the charity's Garlic Row centre, animal welfare assistant Claire Thomas said.
The animals did not seem "too traumatised" by the torrential downpour or standing water in their pens, she said.
However, staff were "gutted" when they saw the devastation caused by the overnight storm.
The rescue centre was among a number of businesses and organisations in Cambridge affected by the overnight storm.
Addenbrooke's Hospital in Cambridge was forced to declare a "major incident" and cancel all planned surgery until Tuesday after an area where sterilisation equipment is stored was flooded.
The cat rescue centre has now been cleaned up and the destroyed posts, toys and blankets piled on the lawn.
It would not be sanitary to dry them out, Miss Thomas added, so they will all need to be replaced.
The Cambridge branch of charity Blue Cross cares for over 400 cats and kittens every year.

Danielle Marr, who is in her final year at The Waid Academy in Anstruther, Fife, has joined the RNLI crew in the town as a volunteer on local lifeboats.
In addition to her studies, Miss Marr will have to carry a pager and respond to emergency calls throughout the day.
She is following in the footsteps of her older brother Anthony.
She said: "I am delighted to join the crew here at Anstruther.
"I've grown up watching my brother volunteer and the difference the RNLI make in our community and I want to be a part in that.
"I've been on a few exercises on both the D-class and all-weather lifeboat and have really enjoyed the experience and look forward to continuing my learning."
The teenager is not the first pupil at The Waid Academy to be granted permission to leave class and rescue those in difficulties at sea.
Station coxswain Michael Bruce joined the RNLI more than 24 years ago when he was at school, and he said he is "delighted" to welcome Miss Marr to the station.
He added: "Having just completed her first exercise afloat since being enrolled, Danielle's enthusiasm to learn and become a competent member of the crew was clear to see.
"My team are looking forward to training with Danielle and preparing her for the challenges that will undoubtedly lie ahead.
"On behalf of the RNLI I would like to thank the Waid Academy for their supportive approach to pupils volunteering in the community and the benefits that come from doing so."
An event to mark the achievements of sailor Alex Thomson in the round the world Vendee Globe race has been postponed due to forecast storms.
