If you're looking spring/summer and you need a tie that's shorter than OTR standard lengths, the first things I would consider are Hober's rough Thai silks. They're meant for spring/summer wear but I think they're versatile enough to be worn year-round in California.
In most parts of California, everything is versatile enough to wear year round. I can wear flannel suits in summer and fresco in winter and be perfectly fine. I still try to somewhat stick to seasonal style, but I don't worry about it as much because well, we don't have seasons.
