June 2017 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 charts show how the weather in recent months compares with the thirty-year average for that month. Bars are shaded red if, in that particular month, it was colder, wetter or duller than normal, and green if it was warmer, drier and sunnier than normal, but as referenced above not all tourism suppliers will necessarily benefit from the ‘green’ months.

June 2017

The average temperature in June was 18.0°C, some 2.0°C higher than last June and 1.9°C up on the thirty-year average. Rainfall totalled 42.0mm for the month, which was 20mm less than last June, and 6mm below the long-term average.

Looking at the number of hours of sunshine we find that the total of 295.7 hours was a remarkable 105 hours higher than in June 2016 and 39 hours up on the thirty-year norm.

In summary, the June weather was significantly warmer and sunnier than is normally the case, but, on the surface at least, it would appear rainfall was about what could be 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.

June once again helped demonstrate this point. Rainfall totals may have been quite close to the seasonal norm, but rain fell on just six out of the thirty days, and on three of these we are talking about trace amounts only. There were two really wet days, the 5th with 11mm and 27th with 24mm.

Temperatures peaked on 20th with a maximum of around 31°C, whereas back on 6th June temperatures struggled to reach a peak value of 16°C. On only one day during June was there no recorded sunshine (27th) and one day with less than an hour (24th). There were seventeen days during the month when the sun shone for more than ten hours.

In short then, the vast majority of visitors to Jersey during June will have enjoyed fabulous whether for enjoying the outdoors.
