The Tokyo Marathon 2024 will be held tomorrow, March 3rd (Sunday) in central Tokyo.
Since marathons are held outdoors, rain, wind, temperature, humidity, sunlight, etc. have a major impact on the competition. Also, people watching the games along the roadside are concerned about the wind and cold.
Weather News not only provides general weather forecasts, but also operates the “Ultimate Weather Forecast (urban weather prediction model),” which takes into account the effects of buildings in urban areas. This time, we will use this high-resolution simulation to explain the weather forecast on the course.
From a synoptic perspective, the weather is perfect for a marathon.
Tomorrow, the winter-like atmospheric pressure pattern is expected to gradually ease, and the weather in Tokyo is expected to be sunny with a minimum temperature of 2°C and a maximum temperature of 13°C. Although it will be cold in the morning, the temperature will rise during the day thanks to the sunshine, and the maximum temperature is expected to be close to normal.
It’s so cold that you need protection during the morning standby time. Please be careful not to get cold by stretching or moving your body lightly while waiting. You can feel the heat while driving during the day. Please drink enough water and salt and be careful of unseasonable heatstroke.
Winds are expected to be calmer than today, with wind speeds of around 3 to 4 m/s even during strong periods. The wind is unlikely to significantly derail the outcome of the competition.
Since the wind will be from the south, there will be a long section of headwinds, especially from the middle to the latter half of the season. Although the wind is not very strong, it can be said that it is a mentally difficult wind direction.
According to urban weather forecasting models, caution is required in the area between Nihonbashi and Ginza.
The Tokyo Marathon is a race that runs through central Tokyo, so it has different weather characteristics than races in the suburbs. Let’s take a look at this using “Ultimate Weather Forecast”.
The “Ultimate Weather Forecast (urban weather prediction model)” operated by Weather News reflects the influence of buildings at an ultra-high resolution of 5 m, and simulates the temperature, heat index, wind direction, wind speed, humidity, etc. in urban areas. This is a next-generation weather prediction model.
In urban areas covered with asphalt, the heat index, solar radiation, and road temperature can also affect the competition, but at this time of year, it is not expected to have much of an impact. The focus this time is on the wind.
Even though the wind is said to be relatively weak from a synoptic perspective, when it passes between buildings in the city center, there are places where the wind is stronger than what was observed by AMeDAS. According to the Ultimate Weather Forecast (urban weather prediction model), this trend is predicted to be most noticeable tomorrow in areas around Nihonbashi and Ginza in Chuo Ward, and around Shiba Park in Minato Ward.
There is a possibility that the headwinds will be stronger than those observed by AMeDAS around the 31-33 km point between Nihonbashi and Ginza, and the 35-37 km point in Minato Ward, so this is likely to be a difficult area in the latter half.
If you are sensitive, take measures against hay fever.
As the temperature rises, it is expected that pollen will fly more easily. Cedar pollen is already in full swing in Tokyo. In a marathon where cardiopulmonary function is important, nasal passages are also important, so you can’t neglect measures against hay fever.
Also, if you are cheering on the runners by the roadside, it will feel colder than the temperature readings if you stand still, so please be sure to protect yourself from the cold by wearing gloves, a scarf, a warmer, etc.
