It's possible to figure out when it's the best time to plant parsley by checking out the USDA zone info for Zone 10a.

Planting Calendar for Parsley

Frost tolerance for parsley:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Parsley are moderately cold tolerant which means that you can get them planted earlier than other plants that might not handle the cold.

The earliest that you can plant parsley in Zone 10a is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant parsley and expect a good harvest is probably October. If you wait any later than that and your parsley may not have a chance to really do well. If you are starting your parsley indoors then you might be able to get away with starting them a few weeks earlier.

Half of the time in Zone 10a you get surprised by a frost after January 31 so always be ready to protect your parsley if you have a surprise late frost.
