Weale, 43, went down 7-4 2-9 2-1, after a tie-breaker against against Australian champion Kelvin Kerkow.
Compatriot Morgan, 63, also had to settle for a silver medal after losing 10-5 9-5 to Malaysia's Siti Zalina Ahmad in the women's singles final.
England's Stephen Farish and Northern Ireland's Margaret Johnston both lost their bronze medal matches.
Farish eased through the preliminary round and quarter-finals, but his winning streak ended in the semi-finals, when he lost to Kerkow 7-7 8-10.
In the bronze-medal match, he took on Canadian Ryan Bester, who had lost his semi-final against Weale 9-9 9-8, but was defeated in a tie-break 9-7 3-11 0-2.
Team England men's lawn bowls manager John Bell said: "Steve was one of the best players in the competition and he didn't deserve to go away with nothing. It just wasn't his day.
"He got a bad result about halfway through the second set, and that took the wind out of his sails.
"In the tie-break he was within an inch from the jack but the Canadian had luck on his side and got a run, which gave him the end."
Llandrindod Wells' Morgan was disappointed at her inability to handle the conditons in the final.
"I'm not disappointed at not getting gold but that I allowed the wind element to get to me," she said.
"I found one end unplayable but Ahmad played it very well, I was always in trouble."
Hereford-man Weale says that the quality of his match with Kerkow compensated for his narrow defeat.
"It was so satisfying to play in such a high-class match as that," he said.
"He drew a magic ball to win. The scenes at the end were amazing, we don't usually see that at bowls!
"I'll be back to try again. The omen is good - bronze in Manchester, silver in Melbourne, perhaps gold in New Delhi!"
