If you are going to a pub or restaurant this week you might be wise to pack an umbrella.
After one of the driest Aprils on record, May is set to start damp with showers forecast before heavier rain arrives on Bank Holiday Monday.
The Met Office outlook for Wales from Friday to Monday says: "Sunshine and showers in the day with dry and chilly nights on the weekend.
"A band of rain then arrives from the west on Monday, bringing strong winds and lower temperatures."
Pubs and restaurants are still expected to be busy for the first weekend since they were allowed to re-open outdoor areas on Monday (April 26).
Welsh weather forecaster Derek Brockway said: "The next few days will be cool with sunny spells and scattered heavy showers. Monday more uncertain but low pressure may bring a dose of wet and windy weather. May likely to be wetter than April!"
Met Office forecaster Oli Clayton said: "The pattern of weather remains consistent for the weekend. The bigger change is happening on Monday. The next few days are in a pattern of sunshine and showers. There will be sunshine but pretty much everywhere will be affected by showers at times.
"Temperatures are slowly increasing to closer to average for the time of year. Temperatures will be in the mid teens by Sunday. Overnight temperatures are cool with a chance of frost in rural areas. Everywhere will be cool overnight.
"From Monday an area of low pressure is approaching from the west. It’s bringing unsettled conditions with a period of wind and rain for many. That’ll be welcome for farmers who’ve had a dry spell.
"It’s the first meaningful rain in several weeks. There have been showers around in southeast wales but this will be the first widespread rainfall that impacts people."
The long range forecast from the Met Office shows more "unsettled conditions" with temperatures below average for the time of year.
Not only has it been one of the driest Aprils, it has also been the frostiest in at least 60 years. There have been 13 days of air frost in the past month, making it the frostiest April since records began in 1960, provisional Met Office data shows. The previous record holder was April 1970, with 11.
