Went up Oak Glen in the past, think it was March, morning was 50 degrees. Breathless Agony in May, cool on the climb up to Onyx but bareable in shorts, jersey and underlayer. Added a windbreaker on the way down and wasn't enough. Froze on the descent, atleast halfway down till it was comfy again. Many riders stuffed newspapers in their jerseys. I was so cold I couldn't smile or move my face.
Ride reports from earlier years mentioned cold, drizzle and heavy fog, also in May. I'd think it's colder this time of the year, and this year overall. Like GMR, it's too unpredictable to call it spot on. But be prepared for the COLD. I've only been there in March and May and it was cold. I'd never descended GMR and been that cold.
As mentioned above, it's the only way up right now and the traffic from the opposite direction was HEAVY, so figure both having to use the same route. The traffic would worry me more than the cold though.
