A decent Sunday, before the clouds start plotting
Culcheth is waking to clear skies and a brisk 9°C, although the very high humidity may make the morning feel more damp than dazzling. Still, the forecast is treating us kindly today, with no rain expected and temperatures rising to around 20°C.
Cloud will drift in and out through the morning, but the afternoon should remain dry and pleasantly mild. Winds will stay mostly light, with speeds generally between 1 and 8 mph, although gusts could reach 14 mph later on. In other words, ideal weather for getting outside without being ambushed by the usual British side quest: carrying a coat you never use.

The 14-day outlook, or the return of proper North West weather
| Day | Forecast | High and low | Wind |
|---|---|---|---|
| Sunday 23 August | Dry with sunny and cloudy intervals | 20°C / 8°C | 6-14 mph |
| Monday 24 August | Generally mild | 20°C / 10°C | 10-24 mph |
| Tuesday 25 August | Warmer conditions | 22°C / 12°C | 12-29 mph |
| Wednesday 26 August | 90% chance of rain, around 2.5 mm | 24°C / 15°C | 8-17 mph |
| Thursday 27 August | 90% chance of rain, around 4.9 mm | 24°C / 16°C | 9-24 mph |

Monday and Tuesday look fairly respectable, though the wind picks up, with gusts potentially reaching 29 mph on Tuesday. Then comes the wet spell. Wednesday and Thursday may be warm at 24°C, but that warmth appears to arrive with a substantial helping of rain. It is very much the North West arrangement: sunshine offered briefly, then invoiced in showers.
Sun, air and August context
Sunrise is at 06:03 and sunset at 20:20, giving Culcheth a generous 14 hours and 17 minutes of daylight. UV levels are low early and late, rising to moderate around midday, so some protection is sensible if you are outside for long. The air quality reading is 32, rated fair, with ozone measured at 79 µg/m³. Grass pollen is low at 10 grains per cubic metre, which is welcome news for anyone whose nose usually treats August as a personal grievance.
For comparison, August in Culcheth typically averages 16°C, with average highs of 19°C and lows of 12°C. The month usually brings around 17 rainy days and 97 mm of rainfall, with average wind speeds of 14 mph. So while this week begins with a promising sunny spell, the later rain is hardly an outrageous betrayal. It is simply August behaving like August.
