But climate is actually the result of a whole bundle of factors, from altitude to proximity to water, ocean currents to butterflies. Kate navigates the fine line between weather and climate, asks, is there anywhere on earth you can go and be guaranteed year-round idyllic holiday conditions? This film is part of our series that provides the blueprint for a scientifically perfect summer. Taking a different topic each Thursday, the videos will gradually build up an equation for summer perfection; a summer survival guide certified by science.
