**Weather Forecast for 04 September 2026 – Sri Lanka**

Sri Lanka is expected to experience a mix of showers and thundershowers on 04 September
2026, with rainfall activity mainly developing during the afternoon. Showers or 
thundershowers may occur at several places in the Uva, Central and Eastern provinces,
as well as in the Polonnaruwa and Mullaitivu districts, after 2.00 p.m. Meanwhile,
several spells of showers are expected in the Western and Sabaragamuwa provinces
and in the Galle and Matara districts.

The public is advised to remain cautious during thundershowers, as temporary localized
strong winds and lightning may occur. People should take adequate precautions to
minimize possible damage and avoid exposed locations during lightning activity.

An important astronomical feature will also affect Sri Lanka during this period.
Due to the apparent southward movement of the Sun, it will be directly overhead 
Sri Lankan latitudes from 28 August to 07 September. On 04 September, the Sun is
expected to be overhead near Nittambuwa, Algama, Malwana, Aranayake, Meegahakiula
and Panamkadu at around 12.09 noon.
