Good and best months depend on more than temperature, rain and events. How they are chosen
Each activity on this page has its own good and best months, rated on twenty years of daily weather records. Which measures count, and how much, depends on the activity: humidity for exploring outdoors, wind for the beach, hiking and skiing, snow for skiing alone. Between them, the activities are rated on:
- Daytime highs
- Night-time lows
- How warm it feels
- Humidity
- How much of the day is sunny
- Hours of daylight
- Monthly rainfall
- How many days it rains
- Days of heavy rain
- Wind
- Snowfall and days with snow
- Major events, such as festivals
The chart shows the good and best months for exploring outdoors.
The event icon marks a month that an event lifts to good or best, such as a festival or a natural spectacle. Choose “Weather only” in the toolbar to rate the months on weather alone.

Air quality
Averaged over a shorter period (2022–2025) than the twenty-year averages above, and not counted towards good or best months.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec | |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Air pollution (PM2.5) 2022–2025 | 7 µg/m³ | 10.7 µg/m³ | 8.7 µg/m³ | 8.6 µg/m³ | 9.1 µg/m³ | 12.4 µg/m³ | 9.4 µg/m³ | 8.5 µg/m³ | 6.8 µg/m³ | 8.2 µg/m³ | 6.6 µg/m³ | 9.3 µg/m³ |
| Air pollution (PM2.5, daily peak) 2022–2025 | 12.3 µg/m³ | 17.9 µg/m³ | 15.2 µg/m³ | 14.4 µg/m³ | 14.6 µg/m³ | 18.2 µg/m³ | 14.2 µg/m³ | 12.8 µg/m³ | 10.7 µg/m³ | 12.9 µg/m³ | 11.5 µg/m³ | 15.6 µg/m³ |
- Good 15 µg/m³ or less
- Fair 15 to 25 µg/m³
- Moderate 25 to 37.5 µg/m³
- Poor 37.5 to 50 µg/m³
- Very poor 50 to 75 µg/m³
- Extremely poor over 75 µg/m³
Each figure is compared with the World Health Organization's guideline for a day's air, 15 µg/m³ or less, and with its interim targets above that. The words are ours: the WHO does not name its steps. The figures are modelled monthly averages, so single days can be well above them. The daily peak is the average of each day's highest hour, shaded on the same scale.
