Taylor Swift powered through some serious rain during her “Eras” tour performance in France this weekend — and so did her fans, which TayTay appreciated … and made known too.

The pop star shouted out the Swifties Sunday who wouldn’t stop dancing during the concert at the Groupama Stadium in Lyon — despite the immense amount of rain.

Here’s what she said … “So it looks like we have officially had a rain show tonight, this is a rain show for sure. And that is set, that is permanent because it doesn’t matter if it rains again, it really did rain during this show.”

Taylor has earned a reputation for battling past bad weather … notably performing all 3.5 hours of her “Eras” tour last year during “a full-on deluge” in Foxborough, Massachusetts.It appears Taylor brought a similar dedication to Lyon … and so did her fans, as she credited them as “absolute champions and heroes for dancing even harder when it started raining.”

She added … “I never could have imagined we would have this much fun on the European tour. It’s just been crazy, you guys and I appreciate you so much.”

As we reported … the singer also took a moment tocheck in on one attendee, who she saw asking for help amid the bad weather. She shared … “Yeah we have to take care of these crowds because you’re just the best and you just dance so wildly and sing so loudly.”
