Paul - I started my thru-hike on March 17th this year & LOVED the cool temps & tons of water in the SoCal desert sections.
This year had great weather after the first weekend in March until April Fool’s Day. I picked the 17th because it was just after Daylight Savings had kicked in & it happened to be St. Patrick’s Day.
I’m not sure when you’re planning to start, but you can always fairly easily use alternate trails & roads to get around tough snow sections. If there’s heavy snow on the Desert Divide & San Jacinto, you can take the Spitler Peak Trail to Bonita Vista RD to May Valley RD to Saunders Meadow RD to Idyllwild to HWY #243 to Black Mountain RD & back to the PCT just past Black MTN Campground.
Baden Powell & the Big Bear vicinity are not nearly as difficult to traverse as the San Jacninto region & there are alternate route options there as well.
Happy Trails,
