# Sri Lanka Weather Forecast for 04 August 2026: Heavy Rain, Strong Winds and Rough Seas Expected

The Department of Meteorology has forecast unsettled weather across much of Sri 
Lanka for **04 August 2026**, with heavy rainfall, strong winds and rough sea conditions
expected in several parts of the country. Residents in vulnerable areas are advised
to remain alert and take necessary precautions as adverse weather conditions continue.

Showers or thundershowers will occur at times in the **Western, Sabaragamuwa and
North-Western provinces**, as well as in the **Kandy, Nuwara Eliya, Galle and Matara
districts**. The heaviest rainfall is expected in **Sabaragamuwa Province** and 
the **Kandy and Nuwara Eliya districts**, where rainfall exceeding **100 mm** is
likely at some locations. Such heavy rain could lead to localized flooding, waterlogging
and difficult travel conditions.

Several spells of showers are also forecast for the **North-Central Province**, 
while **Uva and Eastern provinces** and the **Mullaitivu District** may experience
showers or thundershowers after 2.00 p.m.

In addition to heavy rain, **strong winds of 40–50 kmph** are expected at times 
over the **North-Central, Sabaragamuwa, Southern, Central and North-Western provinces**,
as well as the **Trincomalee District**. The public is advised to secure loose outdoor
objects and remain cautious during thunderstorms, as temporary localized strong 
winds and lightning may pose additional hazards.

### Sea Conditions

Weather conditions at sea are expected to remain hazardous over the next 24 hours.
Showers or thundershowers will affect sea areas extending from **Puttalam to Trincomalee**
via **Colombo, Galle, Hambantota and Batticaloa**.

South-westerly winds will generally range between **30–40 kmph**, but could strengthen
to **60–70 kmph** in the sea areas from **Galle to Pottuvil via Hambantota**. Winds
may also increase to **50–60 kmph** from **Puttalam to Galle via Colombo**.

The sea will be **rough to very rough**, particularly from **Galle to Pottuvil via
Hambantota**, where naval and fishing communities are strongly advised **not to 
venture into these waters until further notice**. Wave heights may reach **2.5 to
3.0 metres** from **Puttalam to Pottuvil** via Colombo, Galle and Hambantota. Mariners
should remain vigilant, as temporarily strong gusty winds and very rough seas are
likely during thundershowers.
