All set for hottest day of the year Parts of the country are expected to reach temperatures of up to 79F (26C), while forecasters are predicting highs of 86F (30C) by the end of the week. The warm spell will mark a welcome change after a chilly June. It followed one of the coldest springs on record.

The statistics show that the nationwide average this month was 56F (13.4C), 1.4F (0.7C) below normal. It is the country's joint coldest June - equal to June last year - since 1991, when the average temperature was 53F (11.8C). Although it has been cool, there is some consolation.

Forecasters at the Met Office said that after the slow start, this week should bring some signs of a proper summer. The South East is expected to get the best of the weather today and through the week. The North and West should expect cooler and showery conditions.
