It is. "ironic" was a French loanword, but when it was shoehorned into English, forms like "ironically" made the redundant addition of "-al" natural for some. Both have been in common use for many centuries. I'm still far more used to the terser "ironic" myself though. "ironical" seems alien and strange to me.
