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.
The average temperature in February was 4.9oC, a whopping 3.1oC lower than the year before and 1.6oC below the thirty-year average. Rainfall totalled 56mm for the month, which is substantially less than fell in February of 2017. amount of rainfall in February 2018 was roughly 20% below the seasonal norm.
Looking at the number of hours of sunshine we find that the total of 149.4 hours, some 63 hours up on February 2017 (which suffered from persistent fog) and 53 hours above that which one might expect based on the thirty-year average – indeed it was the sunniest month since September of 2017.
In summary, the February weather was very much sunnier and colder than is typical for the time of year, with the added bonus of also being somewhat drier than could have been expected.
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 February there were just three days when no sunshine was recorded with a further three days when the sun shone for an hour or less.

There were thirteen days with no recorded rainfall and four days with only trace amounts. The wettest day of the month was St Valentine’s Day with 10mm.
