The Thai Meteorological Department has warned of hot to extremely hot conditions
across Thailand from April 4–9, 2026, with temperatures reaching up to 42°C, accompanied
by hazy skies and isolated thunderstorms.

## Key Points

 * Temperatures in upper Thailand (North, Northeast, Central, Bangkok) are expected
   to reach **36–42°C** during the day, driven by a heat-induced low-pressure system.
 * **Hazy conditions** are forecast across most regions during the day, with residents
   in the North, Northeast, and upper Central regions advised to wear **N95 masks**
   outdoors.
 * **Thunderstorms and gusty winds** are expected in scattered areas despite the
   extreme heat, with some rainfall (10–20% coverage) forecast from April 7–9.
 * Bangkok temperatures will range from **26–28°C at night to 35–41°C** during the
   day, with southerly winds at 10–15 km/h.
 * Southern Thailand will see **isolated thunderstorms** with wave heights around
   one metre, rising higher during storms.
 * Mariners have been advised to **avoid sailing** in storm-affected areas of the
   Gulf of Thailand and Andaman Sea.
 * Residents are urged to **avoid prolonged outdoor activities** due to health risks
   from the extreme heat.

## Why It Matters

The Thai Meteorological Department has issued a heat warning from today until April
9. Many areas in Thailand could see temperatures exceed 42°C, along with hazy skies
during the day.

Upper Thailand will be affected by a heat-induced low-pressure system, resulting
in widespread high temperatures and reduced visibility. Weak southerly and westerly
winds are also contributing to unstable weather, leading to potential thunderstorms
and gusty winds in certain areas.

The combination of record-level heat, poor air quality from haze, and unpredictable
storms poses significant health and safety risks across Thailand as the country 
moves deeper into its hot season.

Prolonged exposure to extreme heat can lead to heat-related illnesses, while deteriorating
air quality contributes to respiratory issues, particularly among vulnerable populations
such as children, the elderly, and those with pre-existing conditions. Additionally,
the unpredictability of storms raises concerns about sudden flooding, property damage,
and disruptions to daily life, highlighting the urgent need for comprehensive disaster
preparedness and sustainable environmental policies to mitigate these growing risks.
