AFTER a week of blisteringly hot weather St. Swithin's Day will determine how long we'll keep our sunglasses on for.
The old wives' tale goes that if it rains today (July 15) - it will rain for the next 40 days - while a sunny day will see clear skies for 40 days.
As the temperature peaked at 27C over the weekend, families sat sunbathing in their gardens and headed to the beach to make the most of it.

Although we saw some cloud in Hull yesterday (Sunday) there were still plenty of people strolling through the city centre in their shorts and t-shirts.
Met Office forecasters say the temperature is likely to remain in its 20s this week, after a heat wave alert was issued for East Yorkshire.
The temperature is set to hit 26C later this afternoon as people across the city rush home from the office and slap the sun-cream on once more.
