I would hit the interior of BC first, get it done before fire season really kicks in and if the smoke does get bad early, you can do a quick bug out to the coast and Vancouver Island. 2017 was one of the earliest fire seasons on record and the fires that year started on July 6th. By the July 7th I was on Evacuation Alert, we stayed at alert until Aug 30 when we went to Evacuation Order til Sept 11. We finally went all clear on Sept 21st. one of the longest ever mobilization or our Emergency Support Services. My wife was a volunteer for ESS and still suffers from the ordeal. She was helping those evacuated and could not do much to help ourselves when we were ordered out. We had one complex of fires that was over 1.2M acres. The fire that ended up about 2.5 miles from my home was 475,000 acres. Typically August is the worst month for fires and smoke, but we are being warned to expect earlier and more severe fire seasons due to global warming.
