The weather forecast for Rio de Janeiro today indicates the possibility of irregular rainfall, a common phenomenon during the seasonal transition period. Temperatures can fluctuate between 21.7°C and 29.6°C, showing a thermal amplitude typical of spring. It is important for Cariocas to be attentive to climatic variations throughout the day.
The relative humidity index is expected to be 81%, which is acceptable for the region. However, this humidity can increase the thermal sensation, reaching 28.8°C at certain times of the day. Given this scenario, the probability of rain reaches 86%, forcing residents to take precautions.
How do humidity and UV index affect climate?
Relative air humidity plays a crucial role in climate, directly influencing thermal sensation and precipitation conditions. With 81% humidity, the sensation of heat is expected to be more pronounced than the thermometer may indicate. One ultraviolet index of 3.1, classified as moderate, suggests that sun exposure should be managed with the use of appropriate protection.
In addition, winds blowing at a speed of 14.4 km/h, although not strong, may contribute to a temporary cooling of temperatures during the day, offering relief during the hottest hours of the afternoon.
What are the impacts of unhealthy air quality?
Another relevant factor is air quality, which is expected to be unhealthy. This condition requires additional precautions, especially for the most vulnerable groups such as children, the elderly and people with respiratory diseases. Outdoor exposure should be minimized at critical times, to avoid health problems potentially worsened by air pollutants.
In urban areas, pollutants such as particles and ozone tend to fluctuate depending on weather conditions, influenced by phenomena such as rain, wind and temperature variation. Therefore, the decision to carry out outdoor activities must consider air quality forecasts.
Visibility and astronomical phenomena.
Average visibility is estimated at about 9.9 km during the day, indicating reasonable conditions for travel by land and air, without major restrictions. However, local meteorological factors can influence this parameter.
As for astronomical phenomena, the sun should rise at 5:00 am and set at 6:18 pm, while the moon, in its waning gibbousIt will be born at 23:13 and will hide at 09:17 the next day. These times are ideal for those who want to observe the sky, despite possible weather interference.
Precautionary measures for the coming days
Given the situation presented, the citizens of Rio de Janeiro are recommended to stay informed about possible changes in the weather, equip themselves with appropriate clothing and plan outdoor activities taking into account weather conditions. People sensitive to air quality should be alert and avoid unnecessary exposures.
Therefore, whether to enjoy a walk outdoors or simple urban transportation, it is important to consider all aspects of the climate, guaranteeing safety and comfort during daily activities.
