Fahrenheit	Celsius
Below 32°F	Below 0°C	For swimming this is considered extremely cold. It’s possible you would need to clear surface ice to gain access to the water and unless suitably protected with insulated waterproof clothing hypothermia would very quickly occur.
32 to 46°F	0 to 8°C	The river doesn’t freeze, but it can get down to 37 degrees (F) in the dead of winter. For swimming this is considered very cold and is a risk of hypothermia if exposed for any more than a few minutes.
46 to 55°F	8 to 13°C	This is the range of temperature in the Spring and Fall. Take note: for swimming this is considered cold and any more than a few minutes in the water will be uncomfortable. Low outside temperatures can quickly get a person into hypothermia danger.
55 to 61°F	13 to 16°C	This is the range at the start of summer on the Clackamas. For swimming this is considered cool and for most would feel bracing.
61 to 66°F	16 to 19°C	This is the range for most of July and August on the Clackamas. For swimming this is considered relatively cool but enjoyed by many if outside temperatures are high (above 90 degrees (F))
66 to 72°F	19 to 22°C	Savor these days in August (and sometimes in July) for the most favorable conditions for swimming.
72 to 79°F	22 to 26°C	For swimming this is considered warm and would be enjoyed by all, even those who would normally suggest the water was ‘to cold’ for a swim.
Above 79°F	Above 26°C	For swimming in this is considered very warm and would be enjoyed be all. With this temperature you can stay active in the water for extended periods of time without feeling uncomfortable.
