So we had about 24 signed up for a night hike above LA but with all the smoke in the air there was just seven of us that showed.
Looking west, toward the fires which burned the mountains in the distance
Looking south toward downtown LA
For 24 hrs the offshore wind stopped, and the onshore flow normalized, causing all the smoke over the ocean to drift back inland over LA. We could spot absolutely no fires burning in the distance, but they resumed the next morning when offshore wind restarted. The good news is, the Pacific Ocean makes a pretty good firebreak. The bad news is for you if you picked the Malibu coast to live, given that this exact scenario plays out every couple of years.
I've led our hiking club at work since 1997, with members from all over Southern CA. I also volunteer with the Pacific Crest Trail Association as an Area Coordinator in LA County, and since 1998 maintain the local PCT as a member of the Southern California Trail Gorillas.
