Hearth & Horizon has a new story, The Shadow Rule, set on a school sports day in County Waterford in June 2041.
The checkable parts are small. At about 52 degrees north in mid-June the noon sun stands about 61 degrees up, and a shadow is as long as a person when the sun is 45 degrees up, which here is roughly three hours either side of solar noon. Thin cloud can pass much of the ultraviolet, and a label's SPF is measured at 2 mg of product per square centimetre, more than people usually spread.
