The Copernicus Sentinel-2 captured “satellite cotton clouds” over Munster when it passed over Ireland shortly before midday on Wednesday.

The cumulus clouds are formed when warm air carrying moisture rises and cools, leading to condensation.

Ireland enjoyed widespread sunshine on Wednesday with temperatures rising into the low 20s.

Gurteen in Tipperary recorded 21.8c during the late afternoon.

It also was the warmest day in Dublin since April, with Dublin Airport reaching 21.4c.

Winds will shift westerly during Thursday, and it will be dry once again with long spells of sunshine away from the southwest, which will be cloudy for much of the morning and afternoon before clearing to sunshine by evening. Temperatures will once again range from 14–15°C in exposed coastal locations to 19–21°C further inland.

Friday will mark the final day of what has been an exceptional period of largely dry weather for Ireland that stretches back to the final week of April.
