I’m having an outdoor wedding (both ceremony and reception) in March in So Cal, and it will be quite chilly in the evening.
What would be the best way to let the guests know in advance that they should dress warm?
Should I mention something in the invite? if so, how should I word it?

I was at an outdoor wedding this past August that was at the bride’s family’s summer home in New Hampshire. She included an insert with the invitation that said "Comfortable footwear suggested" on the same paper, etc has the response card. It worked well to let everyone know not to wear heels.
For wording, you could either just make it simple and to the point in the same font as your responses ("Outdoor evening attire suggested") or make it cute/fun ("Don’t forget your sweater!") depending on the feel of your invites.

If you have a wedding website, you could mention it on there. I put it under the FAQ section, so people knew that the wedding was going to be on a lawn (translation: no stilettos).
Otherwise, does the name of your location have a clue as to its outdoor nature? The ___ Gardens, or something similar? Is your wedding small enough that word of mouth would work?
If all else fails, either put it on an insert or print it on the RSVP card. Are most of your guests from SoCal? If so, you can just make sure it’s obvious that your event is outdoors, something like "join us for dinner under the stars." For out of state guests (who often think SoCal is perpetually 78 degrees), you may need to warn them specifically.
