Summer in the tropics means many days are overcast with lots of tropical thunderstorms. my home is about 250 miles south of Melaque. It's much warmer im winter months especially at night. frequently at dawn the temperature in Melaque is in the low sixties Fahrenheit. On the other hand there temperature in our area can be 77 degrees at dawn. Seventeen degrees difference. The lowest temperature I have ever seen in my hometown was 63 degrees Fahrenheit at 6 o'clock in the morning. Locals were shivering and asking to borrow blankets. not one of my neighbors had so much as a light jacket nevermind a heavy coat to wear on those chilly mornings. My last trip northbound found me in Lukeville Arizona in August with a daytime temperature of 122 degrees Fahrenheit and when I arrived in Laughlin Nevada the temperature was 101 degrees at 15 minutes past midnight. with temperatures of 90 degrees at night the rooms become bearable if there is a small air conditioner that can remove the excess humidity. During the day if you stay within a fifty meters of the ocean surf breaking on the beach the climate is very tolerabke but if you will go inland so much as 500 meters the air temperature skyrockets. I remember seeing an air temperature of 40 degrees Celsius in the ithsmus of Tehuantepec in February.
