This paper discusses the different types of analyses of climate for Subang. The climate data were calculated using the monthly hourly averaged.

Overall, the temperature distribution, solar radiation, relative humidity distribution, rainfall distribution, wind-speed distribution and pressure distribution were presented. The least square polynomial of degree four and ten were chosen to represent the climate data. The least square error and the norm of the residual for these two polynomials were the smallest among other polynomials. The coefficients of determination were also calculated. The Fast Fourier Transform (FFT) from MATLAB toolbox was also used to disclose the pattern of the climate data. The FFT shows the Fourier coefficient on the complex plane. A peridogram of power versus frequency and a peridogram of power versus period were obtained for the climate data via MATLAB.
