So, you say in your edited post that 105 until august 21. Then we do an immediate drop to 92 on August 21st.
Of course you also say that's a gradual cool down. Seems like you're just making crap up. Which becomes more evident with each edit.
If we're at 92 on Aug 21, you're king for a day. Of course you say that's from the weather service. I say we're not under 102.
Finally, I posted the article from the weather service front page. Guilty! I'm not smart enough to predict the weather b/c I'm not privy to that type of information, which by the way is extremely expensive information.
From personal experience (age) mainly, I was told by my elders, around the first eight to ten days of Sept the heat pattern does break. That prediction has held fast for many years. So, whomever the weather person was that posted the article, was pretty close to being right. In other words, it is a safe prediction the temperature does break at those dates. In that article, it also said El Niño was getting stronger and that meant an early winter, as in speeded up prognostications. I'd say eight to ten days early as the 21st day of August. Either way, I'm overjoyed the temperatures will be lower than 104.
One interesting note that also is a stable prediction from my elders. At eleven o'clock in the morning, whatever the temperature, add ten degrees to that figure and that will be the high temperature for that day. To make it easy to remember, add ten at eleven..... for the that day's high temperature.
