It is going to be dry and warm day with plenty of sunshine with temperatures on Thursday set to rise to 23°C in Wales.
Some parts of the UK might even see 24°C as the hottest April in six years continues.
It has been dry, sunny and fairly warm since the lockdown began at the end of March.
Temperatures have been well above the average high of 14°C for the month and records show it is the hottest the UK has been this month since 2014, the Met Office said.
Welsh forecaster Sue Charles warned that the sun in the coming days will be similar to the sort of sunshine we would see in August.
She said: "High pressure continues to keep things fine and settled over the next few days. We lose the brisk easterly wind too… so starting to feel warmer."
Her colleague Derek Brockway said Porthmadog was the warmest places in the UK on Tuesday with a high of 20.9°C.
He added: "Bala dropped to 1.5°C last night. Fine and sunny again on Wednesday. High pressure over Norway and low pressure in France means winds but less breezy than Tuesday."
Pollen levels will be high.
Derek added: "April has been very dry so far and warmer than normal but next week cooler with a threat of showers. Signs of a change in May.
"Low pressure bringing more mixed, unsettled conditions. Rainfall nearer average or above. Useful rain for gardens and crops."
Friday will see temperatures drop slightly to 22°C in Wales and south-west England.
Met Office forecaster Greg Dewhurst said there was also a "low chance" of isolated showers in the west of the UK, but said most areas will remain dry.
There is more of a chance of showers over the weekend and temperatures will see a drop.
The Met Office long range forecast for next week says that while confidence remains low, it looks like it is going to be generally more unsettled.
It says: "There will still be periods of fine and dry weather with sunshine but with a greater chance of showers or at times some longer spells of rain developing, especially in the south at first.
"Following this into early May there is a chance of seeing more organised bands of rain arriving into the west with showers, perhaps heavy and blustery, in the north. Temperatures above average to start but becoming a little cooler."
