Im not sure about hottest ever, but they say the day the park opened it was an unusually high 101. And they poured asphalt recently and it was so hot that the asphault was soft and womens heels were sinking in to the ground lol
After posting I was going to change my high estimate to about 109. So 108 sounds about right.
The low however I'm not too sure about. There are always a couple days at least in the winter when I'm driving to work in Irvine where the temp reads 28 or 29 degrees.
Because temperature can vary from location to location (even as little a city block can have variations of a degree or more), weather records are taken from a single fixed position with the same thermometer every time. This reduces error in the measurements. Historically, before digital, it was taken by the same person each time to reduce error in how different people read and interpret a thermometer.
So while it may have been 28 or 29 where you were when you saw the temperature... the official record sits at 30.
With the advent of modern, networked thermometers being widely used, record keeping doesn't so much use a single fixed position any more, but actually goes by the lowest recorded more often.
Our revels now are ended. These our actors, As I foretold you, were all spirits and Are melted into air, into thin air: And, like the baseless fabric of this vision, The cloud-capp'd towers, the gorgeous palaces, The solemn temples, the great globe itself, Yea, all which it inherit, shall dissolve And, like this insubstantial pageant faded, Leave not a rack behind. We are such stuff As dreams are made on, and our little life Is rounded with a sleep. mycroft16 on Twitter
You were close!!! The research really comes from Anaheim highs. I looked for specific Disneyland figures but all seem to come from the temps in Anaheim! I am sure there is a difference.
My guess is that it is usually warmer in DLR than it is outside the park.
It shouldn't be a large enough difference to be a concern.
The "low" will likely be between 4AM and 6AM. If you wanted "coldest at DL when it was open to the public," that will be quite difficult if no one recorded the temperatures.
Sunny California gets cold at night in the winter. I remember going to Disneyland as a kid during Christmas time when the park was open late. Around 10pm, standing in line for Big Thunder....wondering if I could get away with mugging somebody for their gloves (I am a SoCal native...never thought I needed gloves). Now I know.
I remember it being in the upper 20s to around 30 degrees one morning when I got home from work here in Anaheim at 6am. This was when we had the big cold snap back in January 2006. I remember reading about Magic Mt being in the teens up there with pipes breaking and ice everywhere. Do not think Disneyland had any problems..
