Nah, we have cold upwells, it can be upper 70's in one spot and 20 feet out there's 55. So this temperature and moisture is certainly coming from the south, where that 59F night came from is likely a cold upwell that happened and faded.
We have hurricane remnants and monsoonal moisture that has crept further North in the last 20 years, it won't be cooler until October at this point, it's been crazy.
Very happy my AC is working. It's on 100% now for weeks.
