The 34-year-old was signed by the Hammers as cover for Robert Green after falling out of favour at The Emirates.
Almunia is set to deputise for Green once again at Southampton on Tuesday night and admits he is enjoying his spell with the club.
"It's good to feel the game again," he told The Sun. "We will see if I extend my loan. At the moment I am happy - it is a great club with nice people and that's enough for me."
West Ham are currently second in the Championship table following the demolition of Blackpool at the weekend.
