In an album review for Happy Burstday, Gladys Yeo of NME positively described "Thunder" as a "club-ready banger that dives headfirst into the carefree nostalgia of late-noughties EDM and house-led pop music". Clash Isadora Wandermurem praised the song for its "flawless production", deeming it "worthy of the biggest summer festivals". Writing for Billboard, Jeff Benjamin ranked "Thunder" as the best track of its album, highlighting the track's production and "undeniable" whistle hook. == Accolades ==
