I'm just back from filming for the next series of Weatherman Walking.
We went to Llandudno for a walk around Great Orme, a fascinating place with lots of history and wonderful views.
Next we visited the lovely fishing village of Aberdyfi in Gwynedd for a stroll on the beach and up into the hills.
Thankfully, the weather was kind to us and it was dry with sunny spells and warm afternoons.
Last week, temperatures reached the low to mid 20s Celsius but since then it has turned much cooler with some chilly nights.
In Bala, the temperature dropped to 3°C last night with a grass frost - a reminder that autumn is upon us with the longer nights allowing mist and fog patches to form.
This week the weather can be described as changeable; some dry weather and sunshine but also a few sharp showers.
From Wednesday onwards, fronts will move in from the Atlantic bringing rain and drizzle.
Weather chart for 11 September, 2013.
Next week, the signs are that it will turn colder and windier as a deep low pressure near Iceland moves into the Norwegian Sea.
There could even be a little snow on the highest mountains in Scotland. Beyond this, high pressure over the Azores may move towards southern Britain during the end of September - bringing drier, warmer and more settled conditions.
Don’t forget you can get the latest video forecast for Wales and a forecast for where you live.
