Can somebody explain how people are still paying $23 or over that for gas fees in the second half of 2024?

Hi. I was just following an ETH thread in the cryptocurrency subreddit and various people are claiming they are paying about $30 or even more than that for their gas fees for L1 transactions.

For example, I saw this comment:

Yeah I try to swap $45 worth of ETH for a coin I want and it's costing me $23 gas fees. No thanks.

I have read other comments in the past few weeks of people still paying something like upper $20 range for gas fees, and I assume their transactions were recently?

How is this possible though? Checking the gas fee chart at https://bitinfocharts.com/comparison/ethereum-transactionfees.html#1y, the highest average gas fee in the last 6 months was $14 USD on November 13th. The gas fee has generally been lower than that in the last 6 months for Ethereum.

I haven't seen any average gas fee over $20 USD since March of 2024 according to that chart. So how are people still paying like $23, or even in the upper $20 range for their gas fees lately?
