About Thời Tiết — Weather Forecasts for Vietnam and the World
Thời Tiết (dubaothoitiet.asia) is an online weather service providing hourly and 14-day forecasts for all 63 provinces of Vietnam and thousands of major cities worldwide. Our goal is simple: help you know the weather ahead quickly, accurately and clearly, so you can plan with confidence — the morning commute, school runs, travel, outdoor work or farming.
What we offer
Every location page brings the essential metrics together in one clean, ad-light interface:
- Current conditions: temperature, feels-like, sky condition, humidity and wind.
- Hourly forecast: the next 24–48 hours with chance of rain and precipitation.
- 14-day forecast: high/low trends so you can plan two weeks ahead.
- Detailed indices: UV index, pressure, visibility, sunrise/sunset and moon phase.
- Air quality: the AQI plus PM2.5 and PM10 fine-particulate levels.
Everything is presented in a modern, mobile-first design that loads fast even on slow networks, because good weather information should reach everyone, everywhere.
Data sources and methodology
Weather data is provided by Open-Meteo under the CC BY 4.0 license. Open-Meteo aggregates leading numerical weather prediction models from trusted national agencies — ECMWF (Europe), NOAA GFS (USA) and DWD ICON (Germany). These run on supercomputers several times a day, and we refresh continuously to keep forecasts current. Place data comes from GeoNames, and air quality is based on the Copernicus Atmosphere Monitoring Service (CAMS).
We don't operate our own weather stations; we aggregate, present and localize open scientific data into something easy to use — in both Vietnamese and English.
Accuracy and limitations
Weather forecasting is inherently probabilistic: accuracy is highest near the present and decreases for longer horizons (especially beyond 7 days). All information here is therefore for reference only. For critical decisions — maritime, aviation, agriculture, storm response — please cross-check official meteorological authorities and follow their guidance. Vietnam's climate is diverse, from northern spring humidity and monsoons to central-coast storms and the two seasons of the south, and we aim to reflect those regional characteristics honestly.
Coverage
Thời Tiết covers all 63 Vietnamese provinces and cities, grouped by familiar regions, alongside major global cities for travel, study abroad, business and keeping up with loved ones overseas.
