Contrary to popular belief
concrete/mortar etc actually sets better when it's wet. If it's allowed to dry out it won't set properly, because the chemical reaction occurring during curing is a hydration process.

Of course if the rain's so heavy it washes it all away, then it won't work, but cool damp weather is ideal, so long as it's not frosty.

Sorry. Is it too late for science?
