Temperatures rising

[GottmitAlex]

How are the temps directly under the sun in your garden? My local weather station says it's 24C/75F, my thermometer in the shade says 30C/86C but my thermometer at ground level in the garden  directly exposed to the sun as are the coconut palms currently (10:10am) reads 39C/102F.  This surely must count for something.  Pretty sure that the exposed sun temps  are regarded as "those readings don't count" the only ones that count are the ones from registered stations which have a Stevenson box and can  more accurately read the weather under the proper conditions. 

But don't the direct exposed temperatures count for anything? Or are the "relative"?  I understand that the exposed temps only last (in my case) 3-4 hours until the garden gets partial shade once the suns rays are blocked by whatever obstacle(s).

Case in point, if I take a temp reading with my cheapo laser IR pointer on the leaves it reads 35C and when I point it to the soil it reads 46C.

What are your exposed temps?

I've not measured the precise temp but FL summer sun is absolutely brutal. If I go outside without a hat - almost never! - I can feel the sun start to burn my neck within seconds. And that's through 85 rated sunscreen. From our timeshare front window, I watched tourists romp in the Gulf under cloudless sky for hours. Years from now they will wonder how they could develop melanoma in Minnesota.

I am really quite amazed by how sun lover palms like Coccothrinax, Sabals and coconuts thrive in such ferocious sunny conditions.

June was normal. July was hot! August so far has been cooler than normal. No scientific data here, just what I'm used to traditionally....

 

Oh, and I have Syagrus seedlings popping up EVERYWHERE which is a new one for me.

I'm in Guadalajara, MX and during the springtime, which is our hottest season, the temp reaches and stays at 40° C, or more. all day in the direct sun. I have all of my plants on the rooftop and my building is the tallest thing in it's immediate area, therefore I have no relief from the brutal sun. I manage to raise more that 300 varieties of plants, including many  palms and cycads in this antagonistic climate. http://selva.cabal.mx/ I mix my soil in such a manner as to be able to water very frequently and heavily without risking root rot. Yes the plants suffer somewhat during this period, but not excessively and seem to come back with a vengeance once the cooler summer season comes by. 

I think that the trick is to be able to water frequently and heavily while at the same time avoiding the dreaded root rot which so easily occurs with so much water.
