It is hard to come up with a general answer to this question. It all boils down to your own personal preferences. Nonetheless, you should definitely check on conditions before you set out. And you should cancel your camping plans if snow, thunderstorms or extremely hot weather is forecast. As a rule, the best time to camp out is when the temperatures are moderate. If you are planning to make your very first camping adventure, it makes sense to find a campsite that is near home. By doing so, you can always spontaneously decide to go home if you are not particularly comfortable or the weather changes.
