Abstract: This study determined the effect of wind on temperature variation around a gas flare point. The study location is Odagwa a community hosting Shell Petroleum Development Company’s flow station. Temperature measurements were taken within 400m radius from gas flare point in the North, South, East and West directions during day time. The mercury in glass thermometer, merlin digital anemometer brass model, hand held digital compass model 21E and etrex global positioning system were used to obtain temperatures, wind speed, wind direction and geographical coordinates respectively. Results show the following range of values for temperatures at various distances from flare point; D1; 40m (40.2-52.2 oC), D2; 80m (40.2-49.3 oC), D3; 120m (38.2-43.1 oC), D4; 160m (38.2-41.2 oC), D5; 200m (31.1-31.3 oC), D6; 240m (30.1-31.1 oC), D7; 280m (28.8-32.2 oC), D8; 320m (28.6-32.1 oC), D9; 360m (29.1-32.1 oC) and D10; 400m (28.5-31.1 oC). Wind direction was predominantly South West. A high negative correlation was obtained between distance from gas flare point and temperatures in North, South, West and East directions (R2=-0.88, - 0.92, - 0.89, - 0.877 respectively). Plants and animals within the first 200m from flare point are likely to suffer from heat stress and related impacts. Odagwa is an agrarian community hence the arable land within 500m radius from flare point should be put into use other than crop and animal farming. A forest reserve should be developed around the community to provide natural habitat for migrating animals and create a micro climate to check climate change.
