Do you pay attention to 'planting' seasons?

[SoCal_to_Hawaii]

While perusing seed sites and looking at seed packets they, of course, give a recommended planting season (early spring, etc.) Since we don't have the traditional seasons here does anyone bother to follow the seasonal advice, or do you plant whatever you want whenever you want?

Understood that it is wetter in winter with shorter days, but does that make much of a difference?
