As in topic, what is wrong with leaves? I didn't have any frost, so can it be a effect of have rain? The leaves are curled.

Did you have like real warm days recently with plenty of sun? Because that's what it looks to me.

My guess too. Looks to been through several cool days then a really hot day. You have a lot of tender new growth

No, unfortunately I didn't have any hot day, just mild or even cold days as for may days. Few days with heavy rains and lack of sun for few days, that is what I had. 

figpig_66 By tender you mean weak? 

Looks to me they are growing nicely and just stretching out as they adjust to the heavy rain. 
They should perk up nicely when you get some hot sunny days.

mine are doing the same in New York, its happening on my Peters Honey, I am not worried 

My Vistas love to do this when the weather fluctuates.

Glad to hear that. We will have very nice weather for few days so I will see how fig tree will react.

They are fine and look healthy to me

Maris,

Do not think it's a serious problem at all.
Seen figs doing that type of curling - 'cupping' after being given some excessive fertilizer, particularly
phosphate.

I've just check this fig and yea, after nice weather yesterday leaves are becoming straight. So curled leaves was caused by heavy rains and high humidity I think. 

Oh good to know, my little ficazzanna and natalina figlings did that too after some cool wet weather recently.  Things have gotten back to normal, and now my little plants are too.  I was worried they'd been over-stressed or caught something...  My big plants didn't react the same way.

Yeah now I can say for sure that was caused by cool and humid weather. As a proof photo from today, after few very nice days.
