Abstract : Air temperature, humidity, wind speed and direction, and leaf and canopy surface temperature were observed in a mango orchard 3 times between Dec. 1994 and Mar. 1995. The shelter was provided by a railway running N.-S. on the W. side of the orchard and the coast was parallel to the railway line on the opposite side from the orchard. The canopy surface was 4-5°C cooler than the soil. There was a reduction in wind speed on the E. side of the shelter which could lead to cold injury on clear nights. The air temperature of the orchard was higher than that on the W. side of the shelter when the sea wind was slight. The early morning temperature in the orchard was 3-4° lower than that in a mountainous area, but the orchard was 1-2° warmer than the mountainous area by midday.
