Ranthambore Tiger reserve, with its sub-tropical dry climate, The Park has three very well defined seasons – summers, winters and monsoons. October and March are the time when the weather changes from monsoons to winters and from winters to summers, respectively.

Summers start during the end of March and last through the months of April, May and June. During this season the days are very hot and dry. During May and June the maximum day temperature crosses 40 degrees Centigrade and the minimum night temperature still hovers around 30 degrees Centigrade. During the day, hot and dry winds (loo) blow. The maximum day temperature often crosses 45 degrees C in May and June, when the relative humidity is at its lowest.

The monsoons or the rainy season lasts from July to September. This season is warm and humid, with one or two short thundershowers a week. Often there are long periods (10 to 15 days) with no rains. During such long breaks in the monsoon rains, the weather can get very hot and humid. Droughts are a common occurrence in and around Ranthambore. During monsoons the dangs have good cover grasses and herbs and as a result the ungulates tend to concentrate on the dangs and the larger predators follow them there. The average annual rainfall is 800 mm and there is an average of 38 rainy days per year and nearly 90% of them are in the monsoon months.

The winter season lasts from November to February. The night temperature stays below 10 degrees Centigrade, while the day temperature hovers around the 20 degree Centigrade mark. There is often some rain and fog during the mid winters. During December and January the lowest night time temperature goes down to 2 degrees C.
