Mind Cymru said it was positive people were coming forward to seek help, but many were unable to access the support they needed in a timely fashion.
Simon Jones, head of policy and campaigns at Mind Cymru, said those working on the frontline were doing an “amazing job”.
“We need to see how we can support people at an earlier stage so they don’t become more unwell and when they do need the help, it’s available quickly,” he said.
He added more robust data was needed for a clearer picture of mental health services in Wales.
“Behind every data point is a person and their experiences, without the data we don’t know how the system is responding,” he added.
