Not everyone likes June Gloom, but I personally look forward to it. Great break from all the heat, you don't get so burned at the beach, and the cool breeze is the perfect amount of cool. Not San Francisco cold, but perfectly refreshing. It's always a bit disappointing when it sometimes fades away mid-day.
Of course, if it went on too long, it would grow tedious, and when it is foggy in August and September, you feel robbed of your summer, but right now - this June Gloom is great. Hoping it lasts all month.
