Vietnam's weather is becoming more unpredictable, directly affecting people's daily activities. That’s why I created Thời Tiết 4M, a website designed to provide the Vietnamese public with a valuable, superior, and completely free resource to help them adapt to sudden weather changes..
I am Phạm Đức Phương Việt, the founder of Thoitiet4m.com, the leading online weather forecasting platform in Vietnam today.
Vietnam's weather is in constant flux, impacting many industries and aspects of daily life.
In recent years, Vietnam's weather has become increasingly complex and volatile, occurring earlier and more intensely than forecasted. This abnormality is evident through factors such as temperature, rainfall, and flooding.
The shift in weather is often felt dramatically. A clear example is the early days of winter in the North, where temperatures soar above 35°C. The heat feels more like summer, leaving people wondering if winter has disappeared altogether.
However, within just one night, temperatures can drop drastically to 11-12°C as the monsoon low pressure system moves in. Prolonged cold spells bring intense, biting cold that overwhelms the people of Northern Vietnam.

CEO Phạm Đức Phương Việt assesses that weather patterns have experienced significant fluctuations in recent years.
Climate change is causing extreme events to occur more frequently, unexpectedly, and in ways that are hard to predict. This has led to severe damages to both human lives and property.
The fluctuations in climate directly impact humans and production activities:
- Impact on agriculture
- Impact on water resources
- Impact on the economy
- Impact on society
- Impact on human health
Weather 4M - supporting the people of Vietnam in the face of climate change
Given the significant fluctuations in climate, it is crucial to stay updated with daily weather forecasts. This helps people prepare in advance and minimize risks to lives and property.
Understanding this, my team and I developed the Weather 4M website – a free platform that provides weather forecasts for all 63 provinces across Vietnam.

Providing highly accurate data by the hour
The website offers the latest updates on an hourly basis with precision. Users can easily access information on temperature, humidity, rainfall, wind speed, and air pollution levels.
Notably, the website is highly compatible with various devices, including smartphones, laptops, desktops, and iPads. As long as you have an internet connection, you can easily check and update the latest news anytime, anywhere.

The Weather 4M website provides forecasts for each specific location
About CEO Pham Duc Phuong Viet
Pham Duc Phuong Viet is the founder and current CEO of the Weather 4M company. Initially an environmental engineer, he shifted his focus to in-depth weather research before establishing this website.
Previously, he was involved in research work to ensure environmental safety across various production stages. However, Phương Việt realized that this approach was insufficient, as he was often confined to specific projects.
Driven by a deep desire to assist the community, he decided to create a platform that could support millions of people. While working at major corporations, the CEO of Thời Tiết 4M participated in several environmental research projects, focusing on climate change and its impact.

Phạm Đức Phương Việt participated in flood surveys in Central Vietnam (2021)
Additionally, he took part in various training programs to deepen his knowledge of meteorology and enhance his weather forecasting skills during this time.
The meteorological certifications currently held by CEO Phạm Đức Phương Việt include:
- Backyard Meteorology: The Science of Weather (Harvard)
- Tropical Meteorology (MIT)
- Watching the Weather (The Open University)
- Weather Academy
- Introduction to Wind, Clouds, and Weather Services
- Meteorology in a round the World Regatta (University of Barcelona)
After recognizing the perfect moment, Phương Việt decided to establish Thời Tiết 4M with the involvement of long-time collaborators. He also recruited many talented young individuals working in Meteorology, Geology, and Hydrology from across the country to join his team.
He also reached out for partnerships and collaborations with major Meteorological organizations both domestically and internationally to gain access to their massive observational data. These include:
- Vnmha
- Nchmf
- WMO
- NWS
- JMA
Although it has only recently started operations, the website Thoitiet4m.com has already achieved early success. It has been featured by several major domestic newspapers as a promising young enterprise.
A notable mention comes from CafeF, with the article: “Thời Tiết 4M integrates new API technology into weather forecasting” published on May 20, 2024.
Conclusion
Stay proactive in tracking daily weather updates with Thời Tiết 4M, especially in cases of sudden changes, which allows you to make timely plans for response. Make informed decisions about travel, work, and leisure. This, in turn, helps improve the quality of life and minimize unexpected risks.
