Bengaluru Weather: Rain Likely Till June 14, Thunderstorms and Cool Temperatures Expected

After a relatively subdued start to the southwest monsoon, Bengaluru is likely to witness a more active spell of rainfall over the next four days, with weather experts forecasting showers across the city till June 14.

The monsoon arrived in Bengaluru on June 6, following widespread pre-monsoon showers that lashed the city and its suburbs between June 1 and June 5. While rainfall activity has continued since the onset, much of it has remained mild across several parts of the city.

Data shows that Bengaluru City weather station recorded 17.4 mm rainfall between June 1 and June 11, while the HAL weather station received 40 mm during the same period. A significant portion of the rainfall was contributed by pre-monsoon thunderstorms.

Meteorologists attribute the upcoming wet spell to a north-south trough extending across Telangana, Andhra Pradesh, South Interior Karnataka and the southern tip of the peninsula. Moist winds from the Arabian Sea moving across Kerala and Coastal Karnataka are converging with this system, creating favourable conditions for rain.

The trough is also expected to oscillate east and west over the next few days, increasing the coverage of rainfall activity across southern India. Bengaluru is expected to remain one of the key locations benefiting from this weather pattern.

Most of the rainfall is likely during the late afternoon, evening and early night hours. Isolated areas may receive moderate to heavy thundershowers accompanied by gusty winds.

Weather enthusiasts monitoring atmospheric conditions noted that Bengaluru could briefly experience a mild break-phase-like pattern. However, low-level jet winds are expected to remain between 13 and 15 knots, which may still support the formation of thunderstorm cells over and around the city.

Atmospheric parameters currently present a mixed picture. While lower-level convergence remains weak, high humidity levels, favourable dew point temperatures and increased atmospheric instability are expected to aid thunderstorm development.

Experts estimate that Bengaluru could receive another 30-40 mm rainfall during this spell. June is typically one of the wettest months for the city, with an average monthly rainfall of around 110 mm.

The rainfall is also expected to keep temperatures comfortable over the next few days. Maximum temperatures are likely to remain around 28°C, while minimum temperatures may hover near 20°C.

While weather conditions are expected to improve briefly at the beginning of next week, forecasts suggest another round of rainfall activity could return by the middle of the week.
