Pressure and weather in Bengaluru
Bengaluru sits on the Deccan Plateau at roughly nine hundred metres, high enough that its elevation is the main reason the city is far milder than the plains below. Two things dominate the pressure record. First, the elevation: station pressure here averages around nine hundred and ten hectopascals, so readings look dramatically low against sea-level figures and the comparison is meaningless unless the values are adjusted. Second, the monsoon. The city is unusual in receiving rain from both branches — the south-west monsoon from June to September, arriving over the Western Ghats and already partly spent by the time it crosses the ghats, and the retreating north-east monsoon from October into November, which brings the heaviest and most intense evening thunderstorms of the year. Across the whole monsoon period the seasonal trough sits over the subcontinent and surface pressure runs several hectopascals below its dry-season level, a slow seasonal shift rather than the rapid frontal swings of temperate latitudes. At thirteen degrees north the twice-daily atmospheric tide is still clearly visible in the trace, and in the pre-monsoon heat of March to May the chart is otherwise close to flat.
What this means for you
Tropical plateau cities like Bengaluru show gentle seasonal pressure change rather than sharp storm-driven falls, so the useful signal is different. Watching a barometric pressure forecast for monsoon onset and for the intense October and November thunderstorm evenings gives you more than watching barometric pressure today in isolation, and a migraine tracker app may well show humidity and heat matter more here than pressure does.
