2020 Porto Alegre mayoral election
The last mayoral election in Porto Alegre, held in 2020, resulted in the victory of the lawyer and politician Sebastião Melo in the second round. Melo obtained 370,550 votes (54.63% of the valid votes) against the 307,745 votes (45,37% of the valid votes) obtained by his opponent, Manuela d'Ávila (PCdoB).

Approval ratings and 2024 Rio Grande do Sul floods
In a poll conducted in the end of March 2024, Melo's government was approved by 58% of the citizens of Porto Alegre, making him the front-runner in most of the election scenarios. However, after the 2024 Rio Grande do Sul floods that happened in the end of April to May, that also affected the city of Porto Alegre, his lead in polls may be contested. One of the main themes of the 2024 elections will be the reconstruction of the city that is still flooded. The city's protection against floods are responsibility of the mayor of Porto Alegre and during the electoral campaign, his opponents may question his leadership and decisions that've been taken by his government during the floods.

Possible postponement
There was a debate among national political forces about a possible postponement of the elections due to the floods in the state. However, the president of the Superior Electoral Court, Alexandre de Moraes, confirmed on 21 May 2024 that there is no discussions about a postponement. He states that there was no structural damage to the Regional Electoral Court of Rio Grande do Sul and to the electoral courts that would prevent the election from being held in the month of October throughout the state and in the city of Porto Alegre.
