The United Kingdom has no hot season, and planning a campervan trip here means accepting that rather than working around it. Across the six Met Office stations below, the warmest month anywhere is July at Keswick in the Lake District, at a mean daily maximum of 19.8 °C. The strip carries no hot band because the country does not produce one. What it produces instead is wind, rain and light that changes every twenty minutes.

BestWorkableToo hotCold or wetTop figure: average daily high. Below it: average rainfall for the month.

Every figure in the strip is a Met Office 1991 to 2020 mean daily maximum and mean monthly precipitation total for the station named in the row, rounded to whole units. The band is our judgement about the region rather than a published figure. July and August read lower than their temperatures on purpose: in the Highlands and the islands they are peak midge season, and everywhere they are the school holidays, which is the busiest and dearest six weeks of the year on British roads.

Wind is the weather that matters to a van. Stornoway, the Cornish headlands and the Antrim coast all sit with nothing between them and the open Atlantic, and the car parks with the best views are the most exposed places in the country. A high-sided vehicle broadside to an Atlantic gale is unpleasant at best. Park nose into the wind, pick the sheltered side of a headland even when the view is on the other one, and treat a Met Office yellow warning for wind as a reason to move rather than as background noise.
