London is expected to be as hot as Spain as the capital experiences its first real heatwave of the summer. Temperatures are expected to rise throughout the week until next weekend when the mercury is expected to rise to 30°C in London (Heathrow). That’s good news for picnic-goers, but hay fever sufferers are warned that high pollen counts are also on the way.

The hottest temperatures of the week will arrive just in time for the weekend as Friday (June 17) is set to warm the capital to an impressive 30C, compared to Barcelona which is expected to be 29C on Friday. The outlook for the rest of the week remains positive, with Wednesday June 15 through Thursday June 16 also posting highs of 25°C.

The pollen count is expected to be “very high” according to the Met Office which said: “The risk of grass and nettle pollen will increase significantly when good weather occurs.” Sufferers are advised to close their windows and take a shower before bed to avoid the worst effects.

We could have a heat wave as early as next week

The rest of the week will see blue skies that may be interrupted by cloud cover, but in general the days will be clear and bright. These temperatures are in line with the BBC forecast and if they reach 30C it will mean the hottest day of the year so far.

During the heat, NHS advice recommends people stay cool indoors, stay hydrated and out of the sun between 11 a.m. and 3 p.m., regularly apply sunscreen and avoid doing exercise during the hottest times of the day.

Regarding the weekend heat wave, the Met Office writes: “As we approach the end of June, a period of drier than average conditions is expected for the most part, although some periods of rain or showers remain possible almost everywhere. As we head into early July, temperatures will most likely trend towards or above average, with some very hot spells possible.”
