Broome has a pleasant climate by tropical standards as it is on the dry side of the continent and is cooled by water on two sides. There are usually only around 4 days a year when the temperatures soar over 40 deg C and an average of only 46 rainy days a year, of which 29 are in January to March . The tropical lightning storms and downpours during this period are quite amazing .
