There are no "tourism seasons" in Hawaii. Hawaii has the strength of being in a location that offers moderate temperatures year round. We have people from all around the world coming when it's colder in their part of the world. While US travelers from the mainland may use their Summer vacation time to visit while kids are not in school, we see just as many -- if not more -- coming in Dec and Mar.
Here are the DBEDT Arrivals figures for 2018:

Total: 9,888,846 people
Average: 824,071/month
As you can see, June, Jul and August are above average, but December (Christmas break) and March (Spring Break) are very close to July (highest number).
Here was 2019:

Overall, I can't see ANY month or 2-3 consecutive months being labeled "peak season" -- not when the maximum in 2018 was 935,017, and the minimum was 716,055.
