 In warm climates, after about 4 weeks the growth of the shoots starts to rapidly accelerate with the shoots growing in length an average of 3 cm (1 in) a day.In temperate climates, where temperatures can reach above 10 °C (50 °F) in mid-winter, some early budding varieties (such as Chardonnay) can be at risk of premature bud break.This is a potential viticultural hazard in places like the Margaret River region of Western Australia where warm currents from the Indian Ocean can coax Chardonnay vines to prematurely bud in the mid-winter month of July.
