While the East Coast is staring down snowpocalypse 2015, the high hit 70 degrees in Newport, Oregon on Sunday. In January!!!
As the article explains though, it's not totally unusual. Extreme, but not weird.
This prompted me to think... The average high in August in Newport is a mere 66 degrees. Their coldest month's record high is higher than their hottest month's average. The same is not true here in the valley. Our record highs in December/January are somewhere in the mid-60s, while our July/August highs are about 80. Does this happen in your location? Do warm winter temps ever surpass your average summer temps?
Getting warmer than average summer daytime highs in the winter is not unusual at all on the West Coast. Most of L.A's coastal microclimates average highs in the 70s in summer, yet all have recorded highs in the 90s in the winter. Santa Monica has an average high of 70 in July; in July of 2010, it failed to get above 80 F, yet it got 95 F in that November and 84 F in that December. The central coast of California (Monterey, Carmel, etc), summer highs average in the mid 60s with fog. Those locations got highs in the 80s over this past weekend in the dead of winter, much warmer than their typical summer day.
On a side note, we experienced a very unusual phenomenon here in inland Orange County yesterday. Normally, the mornings are much cooler than the afternoons due to dry air. But yesterday, it was in the 70s at 9AM and hit the low 80s by noon. Then the rain came and dropped our temperatures down into the 60s at what is usually the warmest time of the day, 3PM. It rained most of the afternoon and evening with temperatures in the low 60s after a "warmer than a typical summer early morning." These kind of inverted diurnal ranges are exceedingly rare on the West Coast but without fail, rain drops our temperatures due to oceanic influences. Rain is naturally paired with cooler temperatures here so that's the only circumstance that 3PM can be cooler than 9AM.
The West Coast has very different weather patterns than what are seen in most parts of the world. One thing though, when we do get our heat waves on the immediate coast, the dew points are often very low making the "feels like" temperature much lower than in a humid climate. A 100 F on our beach feels cooler than a 90 F in Florida.

70s at 9 AM in summer is the norm for summer here.
average lows are +/- 65 F here in summer and the low is usually reached about 6 AM, then it starts to climb. 70s by 9 AM are a sure thing, especially in Mission Viejo which warms up much faster than the coast. on a normal summer day Laguna Beach would warm from a 65 F low at 6 AM to a high of 80 F at 3 PM, Mission Viejo would warm from a 65 F low at 6 AM to a high of about 93 F at 3 PM.
Now in winter, 70s by 9 AM are not the norm.
just to note, in recent summers the lows have been in the 70s, throughout parts of the area, so what does that say about 9 AM in summer compared to January?
Its impossible here at the coast, the warmest record high in the coldest month is 13°C/56°F, while the average high in the warmest month August is 21°C/70°F.
But it is possible in rare cases though in high lying Alpine valleys which get föhn winds, some places had highs up to 21°C/70°F in early January, while their average max in the warmest month is about 20°C/68°F.
The average high on 1st June at Heathrow is 20c, so a cool summer day may be colder than a record high winter day. Our January record is 17.2c, which can happen on a few days in June, but rarely in July/August.
So would that mean that on June 30th the average high in London is 22C to get a monthly average of 21C?

That's the nature of oceanic climates. There is a shorter range in temperatures
