香港天文台氣溫預報準確率
- 本頁對比香港天文台氣溫預測與最終在天文台錄得的氣溫數字的誤差，從而計算準率
- 天文台官方預測記錄由 1998年05月01日 起
- 只以每日11:30更新的天氣預測作對比
- 由於報文有機會因錯字或其他原因而重發，每日11:30至12:59中最後的更新會被視為11:30天氣預測的最終稿
- 計算準確率的標準如下：
- 先將天文台當日實際錄得的高低溫以四捨五入的方式得出整數，再與之前數天天文台對此日所預測的高低溫比較，得出相應準確率
| 誤差 | 準確率 |
|---|
| 0℃ | 100% |
| 1℃ | 80% |
| 2℃ | 60% |
| 3℃ | 40% |
| 4℃ | 20% |
| ≧5℃ | 0% |
