Pressure and weather in Shanghai
Shanghai lies on flat delta land where the Huangpu joins the Yangtze estuary at the East China Sea, and its weather is governed by the monsoon cycle rather than by a steady procession of fronts. Winter is dominated by the Siberian High: cold surges push southeast across China, and the barometer here climbs to some of the highest sea-level readings on earth, often above 1030 hectopascals, with sharp jumps as each surge arrives. In June the plum rains, known locally as meiyu, settle a stationary front across the delta for weeks of grey, saturated, low-gradient weather. Then comes typhoon season. From August into September, systems curving north out of the Philippine Sea can bring the fastest and deepest pressure falls anyone in the city experiences, and even a storm passing well offshore registers clearly on the barometer. The result is an annual pressure range far wider than most coastal cities of comparable latitude.
What this means for you
Shanghai's three seasons behave very differently, so it helps to tag them separately. Winter cold surges are rapid rises, meiyu is a long flat trough, and typhoons are steep falls. Tracking atmospheric pressure today alongside your symptoms in a migraine tracker app will usually show that one of the three, not all three, is your trigger.
