+---------+------------+------------------+
| Id(INT) | Date(DATE) | Temperature(INT) |
+---------+------------+------------------+
|       1 | 2015-01-01 |               10 |
|       2 | 2015-01-02 |               25 |
|       3 | 2015-01-03 |               20 |
|       4 | 2015-01-04 |               30 |

my solution:

Select w2.Id from Weather w1, weather w2
where w2.date = date_add(w1.date,interval 1 day) and
w2.temperature>w1.temperature;
