Don't even joke, no one on the coast has AC, when it's over 85 outside it's miserable inside! lol.
It probably really is about 95 ambient outside right now, but that soil is just soaking up all that heat, and the sun is so intense right now.
Liam are you a gardener? Should I be doing something to protect my plants right now? I feel like this is a bit too intense lol.

throw some sugarcane or straw about over the soil, it'll help keep the soil under it moist, and cool and will breakdown as mulch and improve the soil.
My sister tells me to germinate most seeds , a drink in late afternoon , very fine show from the hose trigger nozzle for maybe 5min to 10min , don't want to drown the seeds or seedlings.
Then once every other or ever few days depending on how sunny / hot / windy it is for seedlings.
If really hot , consider shadecloth over the beds .
A little bit of soil physics
Emissivity of bare soil

Effect of water content and evaporation on soil emissivity
this is why it's best to water in late afternoon , and this is overthinking it but interesting regarding temperatures at different soil depths
And effect of using mulch to protect soil from summer extremes :

This summarises the effect of different types of mulch
This is why I'm starting all my seeds off in seed trays or seed tubs or biodegradable seed pots. If it gets really hot, I can simply bring them inside .
We're moving into the cooler months here in Australia , so we wont see many days over 26 degC from now til about August / September so protecting my plants from being cooked or deccicated by high temperatures and dry winds and lack of rain is not going to be an issue for me for several months ( and fortunately we have had level 2 water restrictions removed locally and now only at level 1 water restrictions ) , we do get some hot days in winter here ( 28 to 30 degC is not unknown in mid winter ) .
Mind you it was 30 degC here yesterday ( people flocked to the only just reopened beaches in Sydney only to ignore social distancing and loiter and refuse to follow life-savers' and cops' instructions forcing the NSW Govt to order those beached back out of bounds / closed to public AGAIN ).
Are you west of the mountains ( between the ocean and the mounts ) hence subject to the orographic effect , or in the rain-shadow zone ( having mountains between you and the ocean ) ?
