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 few 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.

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.
