BALLINA received the highest rainfall in the state from Saturday to Sunday, with 118mm falling on the coastal town.
Lennox Head wasn't far behind, with 107mm of rain recorded, according to Weatherzone meteorologist Brett Dutschke.
That was the heaviest rainfall for the towns since February last year.
However, the rest of the Northern Rivers was not so lucky, with relatively minimal amounts falling and farmers still waiting for a decent shower to break the second driest year on record.
Lismore received 17mm and Casino 16mm, while Byron Bay and Murwillumbah saw 55mm and 60mm, respectively.
Mr Dutschke said: "It's unusual for August to be so wet. It's been eight years since Ballina had received similar amounts of rainfall in August."
He forecasts showers and possible thunderstorms throughout this week, but no substantive rain until Thursday and Friday, which could bring about 50mm over the two days.
However, Mr Dutschke said this year's rainfall is still hundreds of millimetres below the average and we'd need continuous falls to make up the difference.
"It won't make up the rain the area hasn't got. We're about 300 to 400 millimetres below the average for the first seven months of the year," he said.
"We need to see a few more substantial rain events coming through yet."
Despite the heavy rainfall, the State Emergency Service Richmond Tweed Region only attended one call out last night to a tree that had fallen in Ballina.
No one was injured and no properties were damaged in that incident.
Richmond police Sergeant Tom Kirk said officers also had a quiet weekend due to the rain.
