You will find that as you progress through your training, fewer lessons are cancelled due to weather. Unfortunately you'll probably find around the time you'd doing Instrument Flight you'll have endless days of clear skies... and have to wear those awful foggles. As you get used to turbulence your instructor will let you fly in less calm conditions. The same with crosswinds.
My last PPL lesson was on a horrible windy grey day. We were dodging showers, 'hovering' and even flying backwards ... Fortunately the next day was beautiful so I did my GFT.
