All the things you mentioned, temperature, boat traffic, and improved catches, are the reasons that at this time of year many choose night fishing. With some the inconsiderate boaters, skiers, jet skiers, etc. on some lakes nighttime and dawn are your only viable options. There are many C.C. threads with comments from successful nighttime anglers sharing their experience and tips available here. Safety first - wear a PFD - have someone with you - working lights (boat & utility) - checklist. Good luck.
