It may take longer but if you have deep moisture without being soggy they may still come up. I usually just fluff up the soil and put the seeds on top. I keep four o'clocks for beetle control in a pot. They make tubers and drop seeds all the time so I have to rougue out the ones that escape.
Most seeds need light to geminate and I would rather go shallow than deep.
Happy gardening in Hawaii. Gardens are where people grow.
