Last week most of Wales enjoyed a taste of summer.
At the Royal Welsh Show attendance records were broken and on Thursday in Cardiff the temperature soared to 28 Celsius making it the hottest day of the year so far in the capital.
Since then it has turned cooler and fresher with lower humidity. Daytime temperatures this week between16 to 21 Celsius, 61 to 70 Fahrenheit, which is around average or a little below.
Low pressure near Ireland will also bring us some rain and fresh to strong winds but good news for our wave starved surfers this summer.
Thursday and Friday will be brighter with a mixture of sunshine and scattered showers.
The air will be unstable so the showers could be heavy in places with hail and thunder.
The weekend will continue rather cool and changeable with showers and sunny spells.
So not the best of summer weather this week but at least the pollen count will be low!
Dr Rhys Jones, co-presenter of Royal Welsh Show highlights on BBC Two Wales, blogs specially for BBC Wales Nature this week.
Royal Welsh Show presenters, Rachael, Rhys and Sara.
Well that's it for another year, I've just finished recording the end link with Sara and Rachel, and am now ready to step down from my presenter duties for the Royal Welsh show 2012.
We've had a marvellous time but happy to be on our way for dinner as once again we didn't have time for lunch.
Looking back over the week it's hard to pinpoint single highlights as the whole show has been the most amazing experience.
For me the kindness of the Davies family allowing me to help prepare their champion dairy cows during an incredibly stressful time must top my highlight of my show.
We have all had an amazing time and I hope you have enjoyed watching.
It's a game of two halves weather-wise in Wales today: the south, the east and the Royal Welsh Show have been hot and sunny but it's a different story in the north and west where it's cloudy and cooler.
In Aberporth, there is some fog on the coast with a temperature of 16 Celsius, while in Monmouth the temperature should reach a humid 27C 81F.
The first of the Olympic football matches have been played in very warm conditions in Cardiff, but there is a change on the way.
Over the next few days, it's going to turn cooler and fresher everywhere with a mixture of sunshine, cloud and showers.
On Sunday, the showers could be heavy in places with thunder. Daytime temperatures will range between 15 to 19 Celsius and with lower humidity it will be more comfortable at night for sleeping.
Next week looks more unsettled with some rain on the way with temperatures around the seasonal norm or a little below.
So, after the hottest spell of the summer so far in mid, south and east Wales, temperatures are set to drop.
However, the north and west, which have missed out on the hot weather, will enjoy a few sunny spells.
