The Republic of Ireland is on course to have endured its longest heatwave since the famous long and hot summer of 1976.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\n
\n
\n
\n

In that year, there were 14 consecutive days of the heatwave threshold of 25C or above at Birr Castle in County Offaly and Ballybrittas in County Laois.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\n

So far, up until yesterday, Moore Park in County Cork had recorded 12 days in-a-row of the same temperatures and is forecast to do so again on Friday, making it the longest recorded heatwave for 50 years.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\n
\n
\n
\n

A heatwave in the Republic is when 25C or above is recorded at a weather station for at least five consecutive days, while in Northern Ireland that temperature must be reached for three days at the same site.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

The current heatwave in Northern Ireland has lasted five days in-a-row at Castlederg up until Thursday, but with cooler air forecast on Friday, it looks unlikely to make it a sixth day of 25C or above weather.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\n
\n
\n
\n

That would make it the longest heatwave since June this year and well below the Northern Ireland heatwave record of 13 days in both 1976 and 1995. <\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\n
\n
\n
\n

In the summer of 1995, there were four heatwaves in Northern Ireland which is probably the most recorded in a single summer.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

The summer of 1976 is remembered for its long spell of heat as well as lack of rainfall and people had to collect any rainwater that fell to water their gardens.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\n
\n
\n
\n

The UK Met Office say that due to the planet warming, we can expect more extreme weather events including heatwaves and the speed at which our climate is changing is down to human activity.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\n
\n
\n
\n

Met \u00c9ireann say that heatwaves have become more frequent and more intense globally since the 1950s. <\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\n
\n
\n
\n

Human caused climate change is the main driver of this increase in extreme heat. <\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\n
\n
\n
\n

According to climate projections, it is virtually certain that the duration, frequency and intensity of heatwaves will increase over most land areas.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\n
\n
\n
\n

When will the heatwave end?<\/h2>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Temperatures will fall below the heatwave threshold across the whole island of Ireland this weekend, due to cooler northerly winds. <\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\n
\n
\n
\n

It will still be warm in many counties with some clouds in the north but plenty of sunshine elsewhere. <\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

\n
\n
\n
\n

Apart from a very localised shower, no rain is forecast until at least the middle of next week.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n
