The first car in the queue at Ikea in Ballymun arrived at 5am.
"I knew I would be one of the first, but I expected to see more people," said Muna Diab, who was sitting at the gate in her car at 5am with her 11-year-old daughter Manal.
"We have a new home in Belmayne so we need furniture like wardrobes, and curtains and kitchen stuff," said Ms Diab.
Behind her in the queue at the car park, but first to the door of the store, was Jalanta Vasiljeva (26), originally from Latvia but living in Ireland for 15 years.
"I have moved house so I need a chest of drawers, bathroom shelves, and pots and pans and things," she told the Irish Independent.
"I expected to see queues so I came early and found I was near the top," said Ms Vasiljeva, who had come from Swords and arrived at 6am.
Behind her in the queue were friends Shannon Roberts (23) and Ceri O'Keeffe (24).
By 10.30am opening time there was a queue snaking around the car park with an estimated 300 people in it.
First out the door, with a trolley full of picture frames, was Suzanne O'Regan from Finglas, Dublin. She said her journey was necessary because her print business, Oregano Designs, depends heavily on her supply of stocks.
"I've been relying on deliveries from Ikea over the past few months but it can take a few weeks to get a delivery slot so it's great to be able to get here in person," said Ms O'Regan, who is expecting her third child.
Traffic levels were moving back towards pre-Covid levels, with more people on the roads.
Dublin Town estimated there were some 100,000 people in the capital yesterday.
Buses and trains were back to a normal timetable, but capacity on public transport is severely curtailed for social distancing purposes.
However, some commuters told of how they feel "uncomfortable" wearing face coverings.
Grafton Street was a hive of activity, even though Brown Thomas has decided not to open until tomorrow.
Summer sunshine helped lift the mood for traders and shoppers.
There were some small queues for coffee and clothing shops, but everyone seemed content to wait and obey the instructions of retail staff clad in masks and gloves.
For Dublin's oldest retailer, Tom Monaghan, reopening his fashion store, Monaghans Cashmere, was "more exciting" than when he first opened its doors 60 years ago.
The family run business on South Anne Street, Co Dublin, shut up shop three months ago due to the pandemic.
The 94-year-old veteran retailer, who has traded through three recessions, said at times he feared he "would never see the premises again".
Mr Monaghan told the Irish Independent: "I think it was a more exciting day than the day we opened in 1960. I could never before imagine that these premises would ever be closed for as long as 12 weeks.
"I have never been out of this shop for more than a week at a time. Hopefully, with a bit of patience, we will overcome this and, financially, we'll be able to support it."
Tailor Louis Copeland said he was glad to be back.
"It's the first time I've put on a suit in about three months and it actually fits me better," he said with a laugh.
"It's great to be back open again, our online shop went off the Richter scale during the lockdown, but it's great to meet people again and feel that interaction and the vibe around town," he added.
Henry Street was busy, despite Arnotts not being open until tomorrow, with shops learning how trade under social distancing conditions.
"People seem excited to be back shopping," said Patrick Obispo as he guided people into Korky's shoe shop.
"People are being patient. It is good. We are sanitising any shoes they handle, and the seats as well, and we have hand sanitiser too," he added.
It was obvious that more people were out and about than in the 10 weeks since mid-March.
Fear in colder times had driven people off the city streets back then, but hope and warmth, and some ice cream, brought summer scenes back to the streets.
