November 2018 Weather Round-Up

The day-to-day weather has very little impact on the volume of visits to Jersey, but can play a major role in influencing the types of activities that visitors who are here do, and thereby, the amount of money that they spend.  Some attractions and activity providers thrive only when the sun shines, others see higher patronage on rainy days.

The following tables show the monthly profile of temperatures, rainfall and sunshine over the past three years, the annual change, and finally the variance to the thirty-year average.  When looking at the monthly figures warmer temperatures, drier weather and higher sunshine hours are shaded green, and when looking at comparisons a warmer, drier and sunnier relative outcome is shaded green.


November was about as warm as one would expect for the time of year, but both drier and sunnier than usual.

The average temperature in November was 10.1°C, which was 0.2°C cooler than the year before but 0.2°C above the thirty-year average.  Rainfall totalled 77mm for the month, 34mm drier than November of last year and 29mm less rainfall than the seasonal norm. 

Looking at the number of hours of sunshine we find that the total of 121.0 hours, meaning that November saw 12 more hours than was the case twelve months before and 36 hours more than the thirty-year average.

Averages can be misleading – you can have many values that are a bit below normal being offset by a single value that is significantly above normal.  In meteorological terms for example you could have a month during which 28 days see not a drop of rain, but three days of torrential downpours.  Statistically this might lead to an ‘average’ amount of rainfall for the month, but most visitors would not have experienced ‘average’ weather.

Looking at November there were three days, the 15th, 20th and 27th with no recorded sunshine at all, and one further day with less than an hour. 

The sunniest day was 2nd November with a shade over eight hours.  The lowest minimum temperature was around 2°C on both the 22nd and 23rd of the month, while 6th November got the accolade for warmest day of the month at 15°C.There were 12 days on which no recorded rain fell with a further six days on which only trace amounts fell.  The wettest day of the month was the 27th with 19mm.
