AI Thread Summary
Sunrise and sunset times on May 30th show sunrise at 5:30 AM and sunset at 8:30 PM, indicating a significant lengthening of daylight as summer approaches. However, day length changes little as the summer solstice approaches, with the most rapid changes occurring around the equinoxes. The earliest sunrise and latest sunset do not align with the solstice, occurring weeks before and after. Current weather patterns are influenced by the transition between El Niño and La Niña phases, which can lead to unusual weather events. While the summer solstice is gradually occurring earlier due to the precession of the equinox, this change is minimal, taking about 71 years to shift by one day. Heat waves are not random, but predicting their occurrence remains challenging due to insufficient understanding of their causes, a focus of ongoing atmospheric research.

Sunrise is at 5:30am and sunset is at 8:30pm and it is only May 30th. That is 3 weeks early for summer solstice. Is the first day of summer going to be longer this year? Also on the east coast it was the hottest it has been since 1885. Is there any pattern to the heat waves or is everything just random? Thank you for any answers I can get.

While Evo's link is close it simply does not answer the question.

It is good that you are observing sunrise and sunset times; however you need to make more observations. What you will find is that the day length will change very little between now and the solstice. If fact it will not start changing again until about a month after the solstice. The day length changes rapidly for about a month each side of the equinox in Sept and March. It changes very slowly for a month on each side of the solstices in June and Dec.

If you continue making observations you will discover some interesting things. You will discover that the earliest sunrise and the latest sunset do not occur on the solstice. They are offset several weeks each side. For more info Google the "equation of time".
 
Uh, I would point out that we're currently in the transition period between elNino/laNina phases of the global weather cycle, when weirdness often happens.

What's happening beyond the Arctic Circle is another, much-disputed matter entirely.

This has nothing at all to do with causing when the solstice occurs.

The solstice is getting earlier, but not by much. It will take some 71 years to occur one day earlier. This is due to what is called the "precession of the equinox".

As to your question asking if everything is random. No, it is not. However, we simply don't know enough about what causes such things as heat waves to predict them very accurately. Leaning enough to do so is one of the major purposes of the atmospheric sciences.
 
Hello, I’m currently writing a series of essays on Pangaea, continental drift, and Earth’s geological cycles. While working on my research, I’ve come across some inconsistencies in the existing theories — for example, why the main pressure seems to have been concentrated in the northern polar regions. So I’m curious: is there any data or evidence suggesting that an external cosmic body (an asteroid, comet, or another massive object) could have influenced Earth’s geology in the distant...
On August 10, 2025, there was a massive landslide on the eastern side of Tracy Arm fjord. Although some sources mention 1000 ft tsunami, that height represents the run-up on the sides of the fjord. Technically it was a seiche.
