Hi Dave. The highest dewpoint I can remember seeing in New Zealand is 23 C , and that was at Whangarei in February a few years back. I suppose the sea temperature acts as a moderator of dew point , but seas warmer than 23 C are sufficently close to our northern shores that a well aimed northerly wind could blow in some air moister than dp=23.

Hi Bob, would you know what the highest dew points northern regions like Auckland and Northland have reached while records have been kept?

I’ve seen the DP get up to 22 a number of times in Summer, but haven’t seen it much higher than 23 before.

Thanks Maggiemas. We have kept the layers to a minimum of one. See http://bit.ly/feelslike for more of an explanation.

It will be OK for you to read “1 layer of clothing” as “1 layer of clothing or less” . Bob McDavitt

On the metservice weather forecasts….. where it says “Feels like “27deg”. 1 layer of clothing.” —— shouldn’t that be – ‘no layers of clothing’ to be comfortable’??

Thanks John. Could be guttation — that’s the name of the process which leads to drops of sap on the tips of grass leaves, and occurs when there is an over abundance of sap.

The large drop at the top of the blade of grass would appear to be due to guttation, not dew.
