Tomorrow is shaping up to be one of those days — official forecasts from the Thai Meteorological Department point to scattered thunderstorms across the capital, with highs reaching 33°C. We’ve pulled together the official government outlook alongside international weather models to give you a clear, verified picture of what to expect.

How to access the official TMD forecast?

The Thai Meteorological Department publishes daily updates at tmd.go.th official government weather agency. The site provides regional forecasts broken down by province, with Bangkok Metropolitan listed as a primary region. You can also check the TMD homepage for a quick one-day summary.

What specific data does the TMD forecast provide?

For tomorrow, the TMD Bangkok Metropolitan forecast calls for scattered thundershowers with isolated heavy rain. The minimum temperature is expected at 25-27°C and the maximum at 32-33°C, with southwesterly winds of 10-25 km/hr (Thai Meteorological Department official government weather agency). The TMD homepage also shows a forecast item for 23 August 2026 with 35°C high, 28°C low, heavy rain, 40% rain coverage, and 20 km/hr wind.

The pattern: two official sources offering slightly different numbers (33°C high from the Bangkok forecast vs 35°C on the homepage), underscoring that weather prediction involves constant refinement. The catch: the discrepancy matters for anyone needing precise temperature planning — check the province-specific page rather than the general homepage for your area.

What is tomorrow’s weather forecast for Bangkok?

What are the expected high and low temperatures?

Bangkok tomorrow: high 33°C, low 27°C, according to the TMD’s official Bangkok Metropolitan forecast (Thai Meteorological Department official government weather agency). AccuWeather gives slightly different numbers: a daytime high of 92°F (33.3°C) and a low of 81°F (27.2°C) (AccuWeather global weather service). The difference is negligible — both point to a warm, humid day.

What is the chance of rain?

Thunderstorms are likely, especially in the afternoon. The TMD forecast uses the phrase “scattered thundershowers with isolated heavy rain” without assigning a percentage (Thai Meteorological Department official government weather agency). AccuWeather provides a 67% probability of precipitation and a 16% chance of thunderstorms specifically (AccuWeather global weather service). The UK Met Office model shows a peak rain chance of 70% at one point in the day, with 40% at 9am (Met Office UK national weather service).

What is the wind condition?

Wind from west-southwest at 10-15 mph (10-25 km/hr) (Thai Meteorological Department official government weather agency). This is consistent across both the one-day and 7-day TMD forecasts (Thai Meteorological Department 7-day outlook official government weather agency). The wind direction matters for anyone crossing the Chao Phraya River — boats and ferries may face choppier conditions in the afternoon.

What is today’s weather forecast for the next 7 days?

What is the overall pattern for the week?

The TMD 7-day forecast for Bangkok Metropolitan calls for scattered thundershowers throughout the period with isolated heavy rains. Temperatures range from a minimum of 25-28°C to a maximum of 32-35°C, with southwesterly winds at 10-25 km/hr (Thai Meteorological Department 7-day outlook official government weather agency).

Are there any significant weather warnings?

No extreme heat warning is currently issued for Bangkok or central Thailand. However, reports from April 2026 show the TMD warned of temperatures up to 42°C in parts of the Central region along with isolated thunderstorms in upper Thailand (The Straits Times regional news outlet). For the current forecast period, the pattern is standard wet-season weather rather than extreme heat.

How reliable are 7-day forecasts?

Extended forecasts carry moderate confidence. The TMD’s own data updates daily, and conditions can shift. The pattern: day 1-3 forecasts are generally reliable for broad trends (thunderstorms vs no storms), while days 5-7 are more indicative than precise. Check the TMD daily update each morning (Thai Meteorological Department official government weather agency).

The implication: plan for the week’s pattern but confirm day by day.

What is the weather forecast for Northern Thailand today and the next 7 days?

What are the key cities covered?

The TMD forecast covers major northern cities including Chiang Mai, Chiang Rai, Lampang, and Phitsanulok. Each has a province-specific page on the TMD website (Thai Meteorological Department official government weather agency).

What is the temperature range?

Northern Thailand: scattered thunderstorms, highs 30-35°C. Chiang Mai and Chiang Rai are expected to have afternoon rain tomorrow (Thai Meteorological Department official government weather agency). The 7-day outlook for the North shows similar conditions persisting through the week.

Are there any special advisories?

No extreme heat warning currently issued for the North. However, a March 2026 report indicated the TMD forecast thunderstorms and gusty winds across Thailand from March 22 to 27 (The Straits Times regional news outlet). For now, the advisory is routine: expect rain, avoid flooded areas during downpours.

The pattern: northern cities follow the same wet-season script as Bangkok, just a few degrees cooler.

What does extremely hot weather mean?

When is weather classified as extremely hot?

Extreme heat is defined as temperatures above 40°C in Thailand. The TMD issues heat warnings when this threshold is met (Thai Meteorological Department official government weather agency). In April 2026, the TMD warned that parts of the Central region could reach 42°C (The Straits Times regional news outlet).

What are the health risks?

Heat stroke risk is highest for outdoor workers and the elderly when temperatures exceed 40°C. The TMD recommends staying hydrated and avoiding prolonged sun exposure during extreme heat events (Thai Meteorological Department official government weather agency).

How to stay safe during extreme heat?

• Drink water regularly, even if not thirsty
• Limit outdoor activity between 11am and 3pm
• Wear light-colored, loose-fitting clothing
• Check the TMD heat advisory page before planning outdoor work

The catch: even without an active warning, knowing the 40°C threshold helps residents assess risk as summer approaches.

“The TMD warning coverage in April 2026 reported Thailand could face heat up to 42°C in parts of the Central region along with isolated thunderstorms in upper Thailand.”

The Straits Times regional news outlet

“A March 2026 report said the TMD forecast thunderstorms and gusty winds across Thailand from March 22 to 27.”

The Straits Times regional news outlet

For Bangkok residents and travelers, the choice is clear: carry an umbrella and check the TMD morning update before heading out, or risk a soaked afternoon commute. The forecast models agree on one thing — tomorrow is a wet day in the city.
