This paper is on the assessment of temperature variabilities and its implications for health and livelihoods in Abuja metropolis from 2019-2024 as well as the assessment of high temperature and coping mechanisms in Abuja metropolis. High temperature facilitates heat stress, deaths, cardiovascular diseases, mental health, asthma and risk of accidents. Cross sectional survey design techniques were deployed with questionnaire as the primary source of data. Analysis on household size of the study showed that 18.37% accounted for 0-3 households, 41.47% accounted for 4-6, while 39.64% and 0.52% accounted for 7-10 and 11 and above respectively. The result further reveals that males have 81.4% and females 18.6% in terms of sex respondents while bracket ranges from 18-25 (19.69%), 26-35 (23.62%), 31-45 (26.50%), 46-55 (17.59) and 56 above had (12.60%) respectively. Two hypotheses of the study revealed a significant effect of health risk associated with high temperature in the study area and significant effect of the strategies adopted by the residents to cushion the impact of high temperature in Abuja metropolis. Findings of the study amongst others show that the mean yearly temperature (January – December, 2019 – 2023 January- August 2024) are within WHO acceptable limit of 370C in all the months, tall buildings within many urban areas provide multiple surfaces for the reflection and absorption of heat, stony materials absorb solar radiation and thus heat up the environment in the city, climate change causes high temperature and that high temperature causes asthma attacks, respiratory and cardiovascular health conditions. Arising from the above, the study recommended that proper implementation of environmental impact assessment of road construction and high-rise buildings should be taken seriously.
