The weather predictions for the week show sunshine with some clouds. Next weekend (16th-17th), however, showers and storms are predicted. This may be a small setback for trade, but it will no doubt be a welcome break for asthma and alergy sufferers, some of whom have found the increase in air polution associated with the heat has worsened their condition.
The temperature will be around 22C max 13C min, and so still take plenty of water if travelling a long distance, and don't leave any pets in vehicles for any period of time.
