A new simple method was proposed to estimate total effective temperature from the maximum and minimum temperatures of a day. Lines connecting the minimum (5a.m.) and the maximum (1p.m.), temperatures of a day with minimum temperature of the next day formed a triangle. The effective temperature of a day was estimated from the area of the triangle which was above the threshold temperature for development. The total effective temperature was calculated by adding the daily effective temperature. This method was found to give more accurate estimation than others.
