Niall McGinn continued his fine goalscoring form with strikes in the 63rd and 81st minutes as Aberdeen moved up to fourth in the Scottish Premier League table.
But Lomas refused to criticise his side as he felt the sodden playing surface and strong wind ruined the game.
"The conditions were farcical today," he said. "I don't want it to sound like sour grapes but that wasn't a game of football.
"The wind spoiled it as a spectacle and I feel sorry for any fan that had to pay. I didn't enjoy one minute of it.
"I don't know about summer football but there have to be measures taken."
Only a fine goalkeeping display from Alan Mannus prevented Saints from losing by a bigger scoreline and Lomas singled him out for praise.
"All credit to Aberdeen second half. They deserved to win," he said.
"Alan was brilliant, it could've been a lot worse. He pulled off four or five great saves."
