san diego county with beaches, foothills, mountains (up to 6,000 ft) and deserts checks a lot of boxes.
cycling tucson-tombstone-bisbee-sedona-phoenix gives you access to two airports and tons of desert scenery and mountains if you want 'em.
a purely desert escape flying into las vegas incorporating death valley np and mojave national preserve would offer lots of solitude.
fly into san francisco and ride the coast down to la-again.
fly into la and ride the santa barbara/santa ynez/san luis obispo/paso robles area. great wine country and lots of greenery/flowers. flats and hills.
what mountains are around are relatively easy to avoid-or attack.
the sf > la coastal ride would be the coolest (daytime) temp wise but all of the rides would find you in the mid-60's to low-80's for daytime highs.
overnight lows for all the areas will be in the low 40's to upper 50's.
