The Swans want more than £20m for the centre-back, who is still getting back to fitness following knee surgery at the end of last season.
West Ham had a number of offers rejected earlier in the summer as they bid for both Mawson and goalkeeper Lukasz Fabianski, whom they signed in June.
Sky Sports News reported earlier this month that Burnley had opened discussions for the defender as they prepare for their first season in European competition.
