We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

The chance that a given day will be muggy in Seychelles is essentially constant during April, remaining around 100% throughout.

For reference, on January 1, the muggiest day of the year, there are muggy conditions 100% of the time, while on August 12, the least muggy day of the year, there are muggy conditions 100% of the time.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

The average hourly wind speed in Seychelles is increasing during April, increasing from 7.0 miles per hour to 8.7 miles per hour over the course of the month.

For reference, on August 17, the windiest day of the year, the daily average wind speed is 17.0 miles per hour, while on April 6, the calmest day of the year, the daily average wind speed is 7.0 miles per hour.

The lowest daily average wind speed during April is 7.0 miles per hour on April 6.

Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere).

Temperatures in Seychelles are sufficiently warm year round that it is not entirely meaningful to discuss the growing season in these terms. We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year.

Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F.

The average accumulated growing degree days in Seychelles are very rapidly increasing during April, increasing by 950°F, from 8,431°F to 9,382°F, over the course of the month.

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series.
