We were in Oahu a few weeks ago and i was surprised to see fog which i now know as vog. I have never seen that before. We had planned a snorkelling trip on that day and was glad that we ended up not going as the weather was just cloudy and "cold" as well.
I'm just wondering, if there is a particular time of the year vog occurs more than another? Planning my next trip back probably in october and just wondering.
