The Dockers delivered an 83-point demolition of the Brisbane Lions on a sodden, wintery night at Patersons Stadium on Saturday.
The Lions' total of 3.4 (22) was the lowest score Fremantle has conceded in its history, eclipsing the previous mark of 4.5 (29) which North Melbourne posted on a wet day in round 13 last year.
Lyon did not shy away from the fact that his Dockers' enjoy playing in the conditions.
"I know we are a good wet weather team," he said.
"That's the first thing. We train in the wet during the week. The players are bouncing around and last year in September we played on a wet day so it doesn't phase us.
"We like it dry but we're not a big tall team so there's nothing wrong with living on the ground for us."
The Dockers' win over Geelong at Simonds Stadium in last year's qualifying final also came in the wet.
Ross Lyon's side has worked its way into the top four for the first time this season on the back of five consecutive wins.
Fremantle faces West Coast in the second derby of the season next Saturday afternoon.
Lyon said he is happy with where his team is placed but warned against any complacency.
"We like sitting there," Lyon said.
"You would rather be there than not be there. But at this point in the year anything can happen and there's lots of water to flow under the bridge."
The Dockers also face selection dilemmas further down the track. The current 22 has been fairly settled but senior players Luke McPharlin, Michael Johnson, Matt de Boer, and Michael Walters will all return from injury before the finals.
Lyon indicated that Walters was ahead of schedule coming back from ankle surgery. Anthony Morabito has also been in tremendous touch in the WAFL racking up another 28 disposals and two goals on Saturday.
The coach was cagey about who might be in the team come September.
"The best 22 tends to pick itself," Lyon said.
"There's some pressure around. But the incumbents - I'd rather to be in than out of the team at the minute."
