The Rainy Season – Start and End Dates

The effects of the rainy season are different in different areas. Understanding these effects can help you make the most of your local environment. Learn about the Start and End dates of the rainy season in your area. Then, plan your vacation accordingly. And remember, rainy season is the best time to travel! For more tips, read the following article. We hope that you’ll enjoy the rainy season to the fullest. We’ll also go over some side effects of the rainy season.

Tropical weather

The climate of tropical areas is characterized by relatively stable temperatures and seasons, with only modest seasonal differences. Although there are four distinct seasons, they usually differ little from each other. In some areas, the weather is consistently hot, with only a few rainy days a year. Other tropical regions experience two seasons, a dry and wet season, with periods of isolated rains during the dry season. However, it is important to be prepared for both types of weather when visiting a tropical region.

The rainy season can start abruptly or a few weeks later than the rest of the year. If daily thunderstorms are expected in a tropical area, a few factors must come together. During this time, temperatures are warm enough to support thunderstorm growth, which then produces rain during the day and overnight. In many tropical regions, rainfall varies significantly from day to day, but generally falls at roughly the same times. As rainfall can be substantial, thunderstorms are common during this time.


For many people, the rainy season is a welcome break from the stifling heat of summer. Cool breezes and greenery are abundant, and the weather cools down dramatically. However, the sudden drop in temperature can also have side-effects, particularly for those with certain health conditions. The humidity locked in the air during the rainy season can encourage the growth of mosquitoes, flies, and other water-borne insects. Those with allergies may experience increased headaches, swollen nasal tissues, and difficulty breathing.

In the United Kingdom, in 2012, excessive rain prevented butterflies from mating. The floodwater also washed away countless families of insects, causing a decline in the population of birds and other creatures that feed on these insects. Farmers rely on rain for their crops to grow. However, excessive rain can damage crops by washing away seeds and topsoil, which encourages the growth of fungus and bacteria. Unusually high rain can also affect the quality and taste of vegetables and fruits.

Start date

In South Florida, the rainy season typically starts around the end of May. But the start date of the rainy season can vary, with some years seeing heavy rainfall before May is over. In other years, it might be a few weeks later. Regardless, the following are the most common days that the rainy season starts. Here are the rainy season dates for Florida cities. This information is only a guide. The exact dates of the rainy season can change, depending on tropical storm systems and droughts.

In recent decades, the ‘normal’ start date of the rainy season in India has shifted by up to 27 days. In fact, the onset of the rainy season in many places has changed by up to 15 days since 1941. This is because of the various factors that contribute to the timing of the rainy season. In addition, rainfall can start up to two weeks later than normal and can last up to a month longer than usual.


Accurate determination of rainy season is crucial to develop strategies for dealing with adverse climate change. A major example is the severe drought of 2001. In the past, the duration of the rainy season varied from region to region and was not consistent with local climate patterns. However, this trend is changing. It is now possible to predict the duration of rainy season more than a century in advance. This paper will explore the factors affecting the length of rainy season in different parts of the country.

When measuring the duration of rainy season, researchers look for differences between positive and negative phases of ENSO. For example, the early onset of rains during an El Nino year is often followed by a longer duration in a La Nina year. Similarly, the late cessation of rains during an El Nino year is more likely to occur in a La Nina year. The duration of rainy season varies according to ENSO phase, although the early onset of the rainy season is accompanied by a corresponding late post-harvest demise.
