Will the sky be clear over Weston-super-Mare on 2 August 2027?
In Weston-super-Mare the eclipse is NOT total. The Moon covers 42.7 % of the Sun at 09:57, but it never gets dark here.
How the ensemble scenarios split for 2 August
— of the scenarios give usable sky
The European model (ECMWF) forecast for the morning of 2 August starts being published on the evening of 27 July, six days before: no earlier model run reaches that hour.
The Sun will be 38.3° up — high enough that cloud overhead does resemble what blocks it.
Where this falls
Each dot is a place with its own reading. The colour is its scenarios.
Hour by hour colour = low cloud
The bar is CLEAR SKY: the fuller, the better.
Where the Sun will be, and why that changes what can block it
In Weston-super-Mare the Sun will be 38.3° above the horizon — reasonably high. Here the overhead cloud really does resemble what crosses in front of the Sun, so the low-Sun warning does not apply.
What time the model looks at, and what time the eclipse is here
Nearby, and why they read the same
Weston-super-Mare shares its model area with these 8: at this range the ensemble cannot tell them apart, so they all come out with very similar numbers.
