## Rough Sea Conditions and Strong Winds Expected Around Sri Lanka

**Colombo, December 29, 2025** — The Department of Meteorology has issued a **marine
weather advisory** warning of **rough sea conditions and strong north-easterly winds**
in several sea areas around Sri Lanka during the **next 24 hours**.

According to the forecast, **showers may occur at a few locations in sea areas off
the coast from Kankasanthurai to Pottuvil via Trincomalee**, affecting parts of 
the **northern and eastern coastal waters**. In addition, **showers or isolated 
thundershowers** are expected at **a few places in sea areas off the coast from 
Kalutara to Hambantota via Galle**, particularly **during the evening or night**.

**North-easterly winds** will dominate marine conditions, with **wind speeds ranging
between 30 and 40 kmph**. However, **stronger winds reaching 45 to 50 kmph** are
likely at times in **sea areas off the coast from Colombo to Kankasanthurai via 
Puttalam**, as well as **from Matara to Pottuvil via Hambantota**.

Due to these intensified winds, the **sea will be rough at times** in the above-
mentioned coastal stretches. Meanwhile, **other sea areas around the island are 
expected to remain moderate**, though conditions may temporarily worsen during thundershowers.

The **Department of Meteorology advises fishermen, naval operators, and small craft
users to exercise caution**, especially in regions experiencing **rough seas, strong
winds, and thunderstorms**. Coastal communities are also urged to stay alert to 
sudden changes in marine weather conditions.
