Pressure and weather in Salisbury
Salisbury lies in southern Wiltshire where the Avon and several tributary rivers meet, in a shallow valley beneath the chalk uplands of Salisbury Plain and not far from Stonehenge. Its temperate maritime climate produces some of the most changeable barometric pressure in Europe, because southern England sits at the receiving end of the North Atlantic storm track. From October through March, depressions steered in on the jet stream cross the country in quick succession, and each brings a substantial fall in current barometric pressure followed by a rise as the associated fronts clear — the deepest of these Atlantic lows account for the country’s most extreme low readings and its damaging winter windstorms. The pattern is rarely settled for long in the cold season, and a single week can contain several complete cycles. The counterpart is the blocking high, which can park over or near the British Isles at any time of year and hold the barometer high and almost motionless for a week or more; when this happens in summer it delivers the region’s driest, warmest spells, and in winter it brings frost and fog to the valley. Sheltered inland from the Channel coast, Salisbury sees somewhat less wind than the shoreline but the same pressure swings. For weather-sensitive residents, a barometric pressure forecast matters year-round here, and most of all through the autumn and winter when weather pressure rarely holds still.
What this means for you
Can barometric pressure cause headaches? In southern England the frequency is the issue rather than any single event, because Atlantic depressions can put the barometer through several full cycles in a week. Pairing this barometric pressure forecast with a migraine tracker app like Pressure Pal lets you see pressure change today and what follows it.
