ST. Joseph, Mo. (News -Press now) – It’s official, St. Joseph – summer has arrived! The first day of summer, also known as summer solstice, will take place on Friday June 20, 2025. This marks the point where the northern hemisphere of the earth is most directly tilted towards the sun, which makes it the longest day and the shortest of the year, the reverse will occur in the southern hemisphere.
On June 20, St. Joseph will benefit from 15 hours and 2 minutes of light, with the sun rising at 5:49 a.m. and complaining at 8:52 p.m. from June 21, the days will gradually start to shorten. When the winter solstice arrives on December 21, 2025, daylight will break at just 9 am and 24 minutes away. So absorb the sun while you can – Summer is there, but the daylight clock already turns.
The longer days are positive for many, especially those who have a love for the outdoors. More solar energy also leads to higher temperatures, hence the relationship between astronomical and meteorological seasons. While the duration and intensity of sunlight ultimately lead to seasonal temperature changes, there is in fact a gap between the longest day of the year and the hottest period of the climatologically.
For example, the average average temperature for Saint-Joseph is around 86 degrees during the summer solstice, about a month later, the average peaks 88 degrees from half to the end of July. Of course, each year is different when it comes to the hottest day due to a multitude of factors such as cloud cover and regional weather conditions.
As if it was in time with the start of astronomical summer, the first heat wave of 2025 will cross the heart of America this weekend. High temperatures will probably remain less than 100 degrees locally, although the mid -1990s is in forecast for several consecutive days. Combined with wet air, this first high heat range will be sufficient to present risks for vulnerable populations, especially after relatively soft temperatures so far this season.
