Vitaly Kim, head of the regional administration, said there wasn't even enough time to raise the alarm over the raids "because by the time we announce this tornado, it's already there".
"The (alert) message and the bombings arrive at the same time," he said on social media.
He gave no details about the extent of the damage or on any possible victims.
Authorities have not yet released an official death toll.
Ukrainian authorities say that Mykolaiv, which they describe as being a "shield" to the key strategic military port of Odessa, some 130 kilometres (85 miles) further west, is resisting Russian attacks and pushing back the invaders' assaults.
Here are the latest developments in the war in Ukraine:
- Ukraine calls on China to condemn 'Russian barbarism' -
Ukraine calls on China to join the West in condemning "Russian barbarism", after the US warned Beijing of consequences if it backed Moscow's attack on the country.
"China can be the global security system's important element if it makes a right decision to support the civilised countries' coalition and condemn Russian barbarism," presidential aide Mikhailo Podolyak wrote on Twitter.
- Hypersonic weapons -
Russia says it has used hypersonic missiles for the first time in Ukraine to destroy a weapons storage site in the west of the country.
Hypersonic missiles travel faster than the speed of sound and can manoeuvre mid-flight, making them hard to track and intercept.
Russia's defence ministry says it used the technology to strike an underground arms depot in the village of Deliatyn, around 100 kilometres (60 miles) from Ukraine's border with Romania.
- Air raids on Mykolaiv -
Russian air raids on Mykolaiv were taking place in quick succession Saturday, Vitaly Kim, head of the regional administration, says, a day after a deadly strike on a military barracks in the southern Ukrainian city.
Dozens of soldiers are thought to have been killed after Friday's strike on the barracks, witnesses tell AFP as rescue operations continue. An official toll has not yet been given.
- Russians in central Mariupol -
Russia says its forces have broken through the defences of the besieged southern port of Mariupol and are now inside the war-torn city.
The mayor of Mariupol confirms to the BBC that Ukrainian and Russian forces are engaged in gun battles in the heart of the southern port, which has suffered relentless shelling.
- Zelensky blasts Nestle, banks -
In a live address to a Swiss rally, President Volodymyr Zelensky blasts firms including Nestle for carrying on business as usual with Russia "even though our children are dying" and tells the country's banks to freeze funds belonging to the Kremlin elite.
- Japan presses India to act -
Japanese Prime Minister Fumio Kishida urges India's Narendra Modi to take a tougher line on Russia's invasion of Ukraine, but a joint statement after talks in Delhi falls short of condemning Moscow's actions.
- 'Hundreds' still trapped in theatre -
Rescuers continue searching for people trapped in a bomb shelter buried under the wreckage of a bombed theatre in Mariupol.
Ukraine's President Volodymyr Zelensky says 130 people have been saved but that "hundreds" are still trapped in rubble after Wednesday's strike on the theatre, where people were sheltering from the Russian shelling.
- 'Time to meet', says Zelensky -
Zelensky calls for urgent talks with Russia, saying in a Facebook video they are the "only chance for Russia to minimise the damage done with their own mistakes".
He has been pushing for direct talks with Russian President Vladimir Putin.
Moscow claims that several rounds of negotiations have made progress on one of its key demands -- that Ukraine becomes a neutral state. Kyiv, which is demanding international security guarantees, denies its position has changed.
- Biden warns Xi -
US President Joe Biden laid out to his Chinese counterpart Xi Jinping the "consequences" of any support for Russia in its war against Ukraine, the White House says.
During their first call since the Russian invasion, lasting almost two hours, Xi said that war is "in no one's interest", but he showed no sign of giving in to US pressure to join Western condemnation of the invasion.
- Strikes near Lviv airport -
Russian forces destroy an aircraft repair plant near Lviv airport but no one is hurt, Mayor Andriy Sadovyi says on the messaging app Telegram.
The western city is just 70 kilometres (45 miles) from the border with NATO member Poland.
- 'Dire' situation in east -
The UN warns that the humanitarian needs are becoming ever more urgent across eastern Ukraine, with a potentially fatal lack of food, water and medicines in besieged cities such as Mariupol and Sumy.

Russia warns that "dilapidated" mines that Ukrainians had deployed in the Black Sea against its "military operation" could drift as far as the Straits of Bosphorus and the Mediterranean Sea.
- 3.3 million refugees -
The First Lady of Ukraine, Olena Zelenska, calls on the World Council of Churches to help organise "real" humanitarian corridors.
