Planning is the secret to effective annotation. There is a lot to add so:
Take it slow and think before you write.
Work out where annotations will fit best before adding them.
You should aim to annotate most of the elements listed below. Remember to use DATA to support what you say (ie state the temperature or precipitation values and name the month(s))!
Maximum temperature (the month with the highest average temperature)
Temperature range (the difference between the warmest and coldest months)
Seasons - look carefully at your graph and try to identify seasons. There might be a hot season and a cold season; a wet season and a dry season; spring, summer, autumn, winter. Identify when they are and describe them.
Anomalies - are there any figures which do not seem to fit the overall pattern?
Comparing climate graphs
Climate data for New York
Draw another graph to show the climate for New York.
In what ways is it similar to the climate graph for Jakarta? Think about all of the elements listed above (maximum and minimum temperature and rainfall; temperature range; seasonality)
What are the key differences between the climate of New York and Jakarta?
What aspects of weather and climate are missing from climate graphs? Why do you think this is?
