The first 16 days come from weather models — highly reliable for the first 3–5 days, gradually less so after that. Days 17 to 30 for Streatham Park are built from climate averages over the last 60 years, so they show typical weather for those dates rather than a specific forecast.
We compare the forecast with the climate average for exactly the same calendar days, calculated from 60 years of observations. The difference shows how the coming month compares with a typical one.
These are real historical extremes recorded in Streatham Park since 1960: the highest and lowest temperature for each calendar date, with the year it happened.
The forecast portion refreshes every hour. The climate portion is based on long-term data and stays stable.
